Kylian Mbappe could yet feature against Lyon on Sunday having already returned to Paris Saint-Germain training following his midweek injury.

Having created PSG's goal in a 1-1 draw at Club Brugge, Mbappe hobbled off on Wednesday with an ankle issue.

Any lay-off would have represented a blow to Mauricio Pochettino, with five matches before the October international break – starting against Lyon and including a Champions League encounter with Manchester City.

Mbappe has been involved in seven goals in all competitions so far this season – the most of any PSG player and joint-sixth across Europe's top five leagues.

The World Cup winner also has a fine record in matches with Lyon, with his eight goals against them in Ligue 1 his most versus any side currently in the division.

But Mbappe could still improve that tally further on Sunday, with PSG reporting "good evolution" of his injury on Saturday.

And Pochettino added in a news conference: "Kylian trained with the group this morning. We'll see how he is tomorrow morning to see if he's part of the group."

With this frantic period of the campaign not aided by a hectic international break for many of his players, Pochettino said PSG would "try to use all our players while striking the right balance".

That could mean a debut for Nuno Mendes, but the PSG coach still has "no date or specific information" on Sergio Ramos' return to fitness.

Meanwhile, Lionel Messi is set for his home bow.

"Leo is calm," Pochettino said. "He knows he can make his debut in front of his fans.

"The team is focused on the game and improving on our Champions League performance and winning the game of course."

Mbappe, Messi and Neymar started together for the first time at Brugge, but none of them were on the scoresheet, with the Argentina great waiting on his maiden PSG goal.

"Players need time, to know each other, to find affinities," Pochettino added. "It will happen with time. We have a very talented squad."

Plenty will be expected this weekend, with Lyon's 1-0 win at the Parc des Princes last December their first victory in 13 league visits.

Mauricio Pochettino admitted he is lost for words when it comes to describing Lionel Messi but said the six-time Ballon d'Or winner has settled in quickly at Paris Saint-Germain ahead of his Champions League debut for the club.

PSG signed Messi in August when financial issues left Barcelona unable to retain him, and he played 24 minutes of his new club's Ligue 1 victory over Reims before the international break.

Messi, who won the Champions League four times with Barcelona, is set to make his bow in the competition for PSG against Club Brugge on Wednesday, and Pochettino told UEFA.com that he is preparing well.

When asked to describe his compatriot, Pochettino said: "I may not be the most appropriate person to describe him. There are many more people who have a wider vocabulary to describe him closer to the reality Leo deserves.

"He will always be considered among the best in the world. Since he arrived, he has really adapted very quickly and he's been training very well, trying to achieve his highest level as soon as possible to compete at his best.

"I didn't think it was possible [that he would sign for us], and when an opportunity appears and everything goes so fast, you can't immediately process it. However, there's that connection: we both are Argentinian, we both support Newell's [Old Boys], we both come from Rosario.

"I have also admired him for a long time when facing him as an opponent, so having him now training with us is really nice. We hope that, together, we will be able to achieve what the club desires."

Messi's experience in the Champions League is matched by team-mate Sergio Ramos, who won the competition four times before joining PSG from Real Madrid in July.

Pochettino, who admitted that most of the players in his squad deserve to be in his starting line-up, said Ramos would be able to guide younger colleagues through the pressurised environment of Europe's top competition.

"Sergio is also a player that we think can, given the possibility, convey his experience, his competitiveness," said Pochettino.

"He's a player that has also won everything, just like Leo.

"It's good having him at the club for all that he can share with his team-mates: all that experience he gained at Real Madrid."

Mauricio Pochettino insisted Kylian Mbappe has plenty of love for Paris Saint-Germain after the speculation surrounding a move to Real Madrid last month.

PSG reportedly rejected three bids - the last one said to be worth up to €200million - from Madrid for the 22-year-old, whose contract with the Ligue 1 giants runs out at the end of the season.

Mbappe has so far turned down the opportunity to sign a new deal, though the speculation has not affected his form, and he scored with a typically composed finish in PSG's 4-0 rout of Clermont on Saturday.

The France forward has now scored against 26 of the 27 teams he has faced in Ligue 1, while he has also directly contributed to a goal in each of his last 10 appearances in the competition.

Mbappe, who was taken off with 11 minutes remaining, ended Saturday's match with a game-leading five attempts, with three of those on target, including a shot that was parried out to Idrissa Gueye for PSG's fourth goal.

However, prior to his strike against Clermont, there appeared to be something of a mixed reaction from the PSG faithful at Parc des Princes, with some sections of the home fans appearing to whistle and jeer the youngster.

Pochettino claimed not to have heard anything untoward, but was adamant that Mbappe has nothing but respect for PSG.

"I didn't hear the whistles, but I heard the ovation he received when he went to take a corner in the second half with the affection of all the supporters of Paris," Pochettino told a news conference.

"He is a great professional, a great player and a good boy, he has a lot of love for this club. He has shown it since he got here.

"He is focused on improving every day, helping the team and fulfilling the club's goals. He shows great respect every day for this club, you have to salute him."

Next up for PSG is a Champions League encounter with Club Brugge. Lionel Messi and Neymar, who were both absent for Saturday's match, are likely to return and may well start in a front three with Mbappe for the first time.

Mauricio Pochettino has confirmed Lionel Messi and Neymar will not play against Clermont, while reaffirming that Kylian Mbappe is perfectly happy at Paris Saint-Germain.

Messi, who made his PSG debut at Reims before the international break, and Neymar both played as late as Thursday in respective World Cup qualifiers for Argentina and Brazil.

While Neymar scored and provided an assist in Brazil's 2-0 win over Peru, Messi netted a hat-trick against Bolivia, surpassing Pele as the all-time leading goalscorer for a South American nation in the process. Argentina subsequently celebrated their recent Copa America triumph with fans finally allowed back into the stadium in Buenos Aires.

Angel Di Maria and Leandro Paredes also featured for Argentina and Pochettino said a common-sense approach dictated none of the players would be involved in Saturday's home match against newly promoted Clermont.

"Di Maria, Paredes, Neymar and Messi, due to common sense, they are not going to be involved in the squad tomorrow," Pochettino told a news conference, though PSG's coach is hoping to have Mauro Icardi, Presnel Kimpembe and Mbappe – who suffered a calf injury while on France duty – will be fit to feature.

Mbappe was at the centre of one of the biggest stories of the recently closed transfer window, with PSG rejecting three bids from Real Madrid for their star striker.

The 22-year-old only has a year left to run on his contract and reports have suggested Madrid are confident he will sign for them as a free agent in 2022. For now, though, he remains at PSG, where Pochettino insists he is content.

"Mbappe is happy. He is emotionally stable. Before the end of the transfer window and now, he has stayed in the same positive mindset with the desire to play and enjoy himself," he said.

"So we are happy with how he is feeling. He has been training and recovering from the injury that he picked up on international duty. We hope he can be available tomorrow."

While PSG have incredible star power in attack, Pochettino has been keen to point out there is a balance to be struck. Indeed, his side conceded five goals across their opening three Ligue 1 fixtures and though they sit pretty on 12 points from four matches, the former Tottenham boss knows there is work to do.

"I think all the players at PSG are stars. Some might play more or less, but they are all stars," added Pochettino, who is also set to be shorn of Marco Verratti on Saturday.

"PSG as a club is bigger than any individual. We have a squad of around 35 players, they all need to feel important. In terms of managing the squad, which is our job, we need the tools so that the 35 players can feel at home and accept their place but at the same time, there are some fantastic names.

"We have to make sure they work as a team because this is a team sport and that is a big challenge that we face. I have been saying that since the start, so we are going to work hard so that it is not just about the names of Kylian, Neymar or Messi, but so that everyone feels comfortable.

"They all need a team, a structure and an organisation to win games so that has to be our main thought. We all drive towards that."

Two of PSG's latest arrivals are yet to make their debuts. Euro 2020 winner Gianluigi Donnarumma has been on the bench for the last two games, while Sergio Ramos is still working his way back to fitness.

Asked if Donnarumma could make his bow against Clermont, Pochettino replied: "We haven't decided yet who is going to be in goal. We have different options – Donnarumma is one of those options."

Pochettino also confirmed Saturday's game, as well as next week's Champions League meeting with Club Brugge, would come too soon for former Madrid captain Ramos.

"Ramos is still undergoing recovery and will not be available for that match," he explained.

"He is following the steps. We want all the players to be available as quickly as possible but it is not something that worries me. I am sure Sergio will recover well and be available soon."

The transfer window does not close. It slams shut, and on Tuesday, it slammed shut with a flurry of late activity.

LaLiga champions Atletico Madrid were heavily involved, with Antoine Griezmann re-joining the club on loan from Barcelona while Saul Niguez left for Chelsea.

It marked the end of a difficult window for Barca, who of course lost Lionel Messi to Paris Saint-Germain, who rounded off a stellar three months by not only keeping Kylian Mbappe, but also adding promising left-back Nuno Mendes.

Earlier in the day, Cristiano Ronaldo's sensational return to Manchester United had been confirmed, perhaps putting the Red Devils right in the mix for the Premier League title, while Chelsea - buoyed by Romelu Lukaku's comeback - cannot be ignored.

Here, Stats Perform looks at the winners, and losers, of what has been a chaotic transfer window.

THE WINNERS

Paris Saint-Germain

Let's start with the obvious. Achraf Hakimi, Mendes, Sergio Ramos, Gianluigi Donnarumma, Georgino Wijnaldum and, of course Messi. Oh, and PSG kept hold of Mbappe, too, rebuffing three bids - the final one reportedly worth €200m - from Real Madrid for the 22-year-old superstar who is out of contract next year. Speaking of out of contract players, Ramos, Donnarumma, Wijnaldum and Messi were all brought in for combined fees of €0, although their wages are sure to be astronomical even by PSG's standards. In Mbappe, Neymar and Messi, PSG have, on paper, what could be the most feared attacking trident of the modern era, not to mention Angel Di Maria in reserve. Mauricio Pochettino's side look suspect defensively but have Ramos to come in, while Donnarumma will compete with Keylor Navas. If they do not win the Champions League this season, will they ever manage it?

Manchester United

It remains to be seen whether United really needed to go out and buy Ronaldo, but the temptation – and reportedly, the requirement to get one over on noisy neighbours Manchester City – was just too much. However, there is no doubting Ronaldo brings a focal point you could argue was still missing from the Red Devils' attack, though with so much quality at his disposal the pressure will be on Ole Gunnar Solskjer to deliver a trophy. United spent big on Jadon Sancho and also brought in a world class defender in Raphael Varane. A title tilt might not be expected just yet, but silverware in some form must be the goal now. After fan protests during the botched Super League proposals earlier this year, the Glazer family seem to have gone all out to prove they want success.

Chelsea

When it comes to Premier League title contenders, Chelsea have surely put themselves well in the running. The European Champions have brought in two major additions in the form of Lukaku and Saul, both players with a wealth of experience at the highest level, and both on the back of title-winning campaigns last season. The Blues did sell Tammy Abraham, Olivier Giroud and Kurt Zouma, among others, but the strength in depth Thomas Tuchel has to play with is remarkable. A deadline day move for Sevilla's Jules Kounde did not materialise, but Saul adds another fantastic option in midfield to go alongside N'Golo Kante, Mateo Kovacic and the in-form Jorginho.

Tottenham

For a long while, it looked as though Tottenham would be one of the big losers from this window. A prolonged managerial search eventually resulted in Nuno Espirito Santo's appointment, but the main saga was over Harry Kane's future. City reportedly made one bid, during Euro 2020, which was dismissed out of hand. The champions never did return with an improved offer, despite huge speculation, and Kane ultimately stayed put. Older players such as Joe Hart, Toby Alderweireld, Erik Lamela and Moussa Sissoko were moved out, while Bryan Gil, Pierluigi Gollini, Cristian Romero and Emerson Royal – a deadline day arrival from Barca – arrived to fill the gaps. Serge Aurier's contract was terminated, while three wins from three means Spurs sat top of the league heading into the international break.

Atletico Madrid

While Saul was a deadline day exit, Atleti have given themselves a great chance of retaining their LaLiga title. With rivals Madrid failing to land Mbappe, as well as losing two of their stalwarts, and Barca seemingly in disarray, there has never been a better opportunity for Diego Simeone's team to really assert themselves as top dogs in Spain. Griezmann's arrival, on a season-long loan with the option for either club to extend the switch, has bolstered a fearsome attack that already included Luis Suarez, Angel Correa, new signing Matheus Cunha and Joao Felix - though the latter may now find chances to play in his preferred position, nominally off the front man, even harder to come by. Saul was struggling to nail down a regular spot in the first team, but Atleti showed greater desire to keep Kieran Trippier, who stayed despite interest from the Premier League. Rodrigo de Paul also arrived from Udinese.

THE LOSERS

Barcelona

The chickens have finally come home to roost at Camp Nou. Years of mismanagement, and the impact of COVID-19, has left the club's finances in a shambolic state. Barca had agreed to a new deal with Messi only to then announce the deal could not be completed due to "financial and structural obstacles". Barca ended the window by selling promising youngster Ilaix Moriba to RB Leipzig and shipping off Emerson to Spurs. Then, late on Tuesday, Griezmann, who cost Barca €120m in 2019, was sent back to Atleti. Luuk de Jong, a target man Ronald Koeman worked with during his stint as the Netherlands' coach, was drafted in from Sevilla as a replacement. Memphis Depay seems ready to step up after his arrival from Lyon, while Eric Garcia and Sergio Aguero also came in on free transfers, though Gerard Pique, Sergi Roberto, Jordi Alba and Sergio Busquets were among the players who took pay cuts in order for Barca to register their latest acquisitions.

Inter

Serie A champions Inter were dealt a blow when, just after ending their 11-year trophy drought, coach Antonio Conte left the club. Financial difficulties meant the Nerrazurri had to cash in on prized assets, and Hakimi and subsequently Lukaku followed Conte out of the door. Lautaro Martinez did stay, however, with Inter reinvesting some of the funds to sign Netherlands right-back Denzel Dumfries, Roma striker Edin Dzeko and Lazio forward Juan Correa. Hakan Calhanoglu, meanwhile, joined from rivals Milan on loan, though it is difficult to see that being enough for Inter to challenge on all fronts this season.

Juventus

While Inter were weakened, it has to be said that Juventus – surely their closest rivals in the Scudetto hunt – also had a disappointing window. Like many European clubs, they have been hit hard by COVID-19, though appeared well set to challenge again after reappointing Massimiliano Allegri. However, Ronaldo decided he wanted out late in the window, and Juve did not stand in his way. An initial fee of £12.86m (€15m), payable over five years, was agreed with United, and Ronaldo left just like that. Moise Kean returned from Everton on a two-year loan with an obligation to buy as a replacement, while Manuel Locatelli was their other major acquisition and Weston McKennie's move from Schalke was made permanent. Based on the performance in Sunday's defeat to Empoli, however, Juve are far from the force they were during Allegri's last spell in charge.

Real Madrid

For a time last week, it really did look as though Madrid were going to end the window in sensational fashion. Three bids were lodged for Mbappe, but PSG did not buckle. Madrid did move for another French youngster – Edouardo Camavinga, who joined from Rennes on Tuesday – but overall it must be considered a poor window. Los Blancos allowed Ramos to leave on a free and sold long-time defensive partner Varane - just the eight Champions League winners' medals between them. Martin Odegaard was deemed surplus to requirements by Carlo Ancelotti and sold to Arsenal, though no buyers were found for fringe players Luka Jovic or Dani Ceballos. David Alaba's arrival on a free transfer from Bayern Munich at least softened the blow of Ramos' departure, and Mbappe may well be on board in 2022.

Manchester City

City broke the British transfer record to sign Jack Grealish from Aston Villa, who in turn have made smart acquisitions such as Danny Ings, Leon Bailey and Emiliano Buendia. While another attacking midfielder was more of a luxury than a necessity, City did miss out on Kane and then seemingly saw Ronaldo snatched from under their noses by United, though the club have claimed it is they who pulled out of the deal. Pep Guardiola went into the window wanting an out-and-out number nine following Aguero's departure, but for now the Premier League champions will have to carry on with makeshift forwards, it seems. Not that it did them much harm in 5-0 routs of Norwich City and Arsenal last month. Meanwhile, wantaway playmaker Bernardo Silva is still at the club, though he will remain a first-team regular.

Liverpool 

Unlike their league rivals, Liverpool never seemed focused on spending big. The Reds instead turned their attention to tying down the futures of key players, with Jordan Henderson, Virgil van Dijk, Trent Alexander-Arnold, Alisson, Fabinho and Andrew Robertson signing new deals. Ibrahima Konate came in from RB Leipzig to boost the defence – a clear area of weakness last season during an injury crisis – though Jurgen Klopp's squad does seem weaker. They have started the season well, but it remains to be seen how they cope without Wijnaldum and even Xherdan Shaqiri should injuries trouble them again.

Mauricio Pochettino revealed how Lionel Messi has already had an impact on his Paris Saint-Germain team-mates after the new superstar signing made his long-awaited debut for the club.

Messi was introduced as a 66th-minute substitute during PSG's 2-0 win over Reims on Sunday, coming on to replace former Barcelona colleague Neymar in the Ligue 1 fixture.

His brief cameo saw him complete 20 of his 21 attempted passes while he was also fouled three times, the six-time Ballon d'Or winner having received a rousing reception upon his introduction from both the home and away fans inside the stadium.

Pochettino was pleased to see his fellow Argentinian settle in quickly to life in French football, revealing how the 34-year-old's presence has lifted his squad as they bid to reclaim the league title.

"He brought serenity to the team. It's important to get off to a good start, even for him," the PSG head coach said after Messi's maiden appearance.

"He was happy and he is well integrated into the group. It was a matter of common sense not to start him in this game.

"The welcome was something very beautiful to see and hear, from our supporters but also from the fans of Reims. Messi was very happy about it.

"The motivation for competition is there for everyone, but his presence brings optimism. Everyone feels it, he has an influence on the other players."

While Messi may have been the main attraction heading into the fixture, Kylian Mbappe stole the show with both goals.

His brace amid speculation over his future helped PSG make it four wins from four at the start of the new league campaign, leaving them top of the table heading into the international break.

Pochettino was particularly pleased to keep a first clean sheet this term too, albeit they benefited from a VAR check that ruled out a possible Reims equaliser for offside.

"It is a significant success for us. We didn't concede a goal, which was one of our main targets before this match," the former Tottenham boss told the media.

"This is not always obvious because the fitness levels are very different from one another. Some players were returning today.

"We are at 12 points. I'm happy before these two weeks of international break."

Mauricio Pochettino described it as a "gift" to have Kylian Mbappe after the forward demonstrated his abilities with both goals in Paris Saint-Germain's 2-0 win over Reims.

Mbappe has been the centre of much transfer speculation having apparently told the club he wants to leave. Real Madrid are seemingly the only runner in the race to sign a player who is in the final year of his current contract at PSG.

There was no questioning his commitment to his current employers on Sunday, though, as the 22-year-old scored twice at Stade Auguste Delaune, in the process overshadowing a debut appearance off the bench for new recruit Lionel Messi.

Madrid have reportedly had two bids rejected for Mbappe, with sporting director Leonardo making clear PSG hope he stays in the French capital.

"Kylian is our player," Pochettino said in his post-match interview on Amazon Prime after a fourth straight win at the start of the new Ligue 1 season.

"You know in football there are rumours, but I think our president and our sporting director are very clear, he is here. 

"We are very happy to have him here, that is. He is one of the best players in the world. It's a gift to have him."

Mbappe has scored or assisted a goal in each of his past nine games in Ligue 1 (10 goals, three assists). 

Both goals against Reims came from crosses, with the opener headed in from Angel Di Maria's delivery. Achraf Hakimi was the provider for number two in the second half, albeit only after the home team had seen a potential equaliser ruled out by VAR for offside.

"Of course we like to play with the strongest and Kylian has shown that he's a great striker," PSG midfielder Marco Verratti told Amazon Prime after the final whistle.

"It's not today that we discover Kylian. He's a phenomenon, everyone expects a lot from him. Sometimes we wait until he misses a game to fall on him but we know him, we are very happy with him."

PSG are unbeaten in 11 Ligue 1 away games (W10 D1), their longest unbeaten run away from home in the top flight since a 17-match streak between February 2018 and January 2019.

A home clash with Clermont is up next for Pochettino's squad, albeit not until after the international break, by which time Mbappe could well have departed for Spain.

Lionel Messi is poised to make a brief Paris Saint-Germain debut after being left on the bench for their Ligue 1 game at Reims.

Neymar and Kylian Mbappe, the latter heavily linked with a move to Real Madrid, were both included in Mauricio Pochettino's starting XI at the Stade Auguste-Delaune.

Pochettino opted to leave Messi out of PSG's win over Brest last time out despite the former Barcelona star training with his new team-mates following his sensational exit from Camp Nou.

However, he confirmed to Amazon Prime on Sunday that Messi would at least play a cameo role against Reims.

He said: "He's [Lionel Messi] is going to be on the bench.

"He arrived late in the pre-season. He's working hard, he can have a few minutes today to start helping the team."

Kylian Mbappe is at the centre of one of the biggest transfer stories as the deadline approaches, but he was still named in Paris Saint-Germain's squad on Sunday as Lionel Messi looks set for his debut.

Mbappe has been the subject of two bids from LaLiga giants Real Madrid, though PSG are reportedly refusing to enter negotiations for the 22-year-old, who only has a season left to run on his deal.

Whether PSG buckle before Tuesday's deadline remains to be seen, but Mbappe trained as usual this week and Mauricio Pochettino insisted on Saturday that the France star had not told him he wished to leave the club.

Pochettino also confirmed Mbappe, along with Messi and fellow superstar forward Neymar, would travel for the clash with Reims and all three were subsequently named in the 22-man squad revealed on Sunday.

Mbappe scored his first goal of the Ligue 1 season in last week's 4-2 win over Brest, while Messi is still awaiting his debut since a shock move from Barcelona earlier this month.

Neymar, who guided Brazil to the Copa America final – a clash that Messi's Argentina won 1-0 – also makes his return to the fold having missed PSG's first three matches this season.

Angel Di Maria scored Argentina's winner against Brazil and also netted on his comeback against Brest, and with Mauro Icardi injured, Pochettino seems likely to pick three of the aforementioned players to start at Stade Auguste-Delaune.

"Kylian Mbappe is working very hard and is preparing for [Sunday's] game," Pochettino said on Saturday.

"In terms of communications with our president and sporting director, they have made it clear what the club's stance is in this regard."

Asked for an update on the situation after Madrid's win over Real Betis, Carlo Ancelotti told reporters: "We should stick to talking about the game because the rest is a matter for the club, who are working on it.

"I don't know the details at this stage."

Lionel Messi could be in line to make his Paris Saint-Germain debut as Mauricio Pochettino confirmed the former Barcelona star will be in the squad for Sunday's meeting with Reims.

PSG, who have won their opening three Ligue 1 fixtures, travel to Reims for their final match before the international break.

Messi, signed on a free transfer from Barcelona earlier this month, did not feature against Brest last time out despite having trained with his new team-mates, while Neymar was also absent.

As speculation continues over the future of Kylian Mbappe amid interest from Real Madrid, Pochettino confirmed that Messi, Neymar and the aforementioned France star would all be involved in some capacity on Sunday.

"They will certainly all be in the squad, so we will see if they are in the starting 11 tomorrow," Pochettino told a news conference.

"We will assess how he is doing and then see if he is in the squad or not. I haven't given a precise answer yet, so I think it is normal for there to be doubts about that.

"When we sign a player, we try not to have big expectations, but to discover and find out information when we are together. Every club is different so you cannot make comparisons.

"What we are finding out about Leo is that he is a professional and a great player, although we do not need to say that. He is adapting very well to his new club, new team-mates and a new environment."

Asked how Messi will fit into PSG's style of play, Pochettino said: "We are a team that likes to play on the front and keep possession. So, I think that is also what he is used to doing.

"For a player like him, he will certainly play a key role in the French league – regardless of the different attributes that the league has compared to England and Spain – because we are talking about one of the best if not the best player in the world.

"I don't think there will be any issues of him settling in, and he is looking forward to making his debut and helping the team reach its objectives."

With Messi and Neymar waiting to feature, Mbappe opened his account for the season in the 4-2 win over Brest. The 22-year-old has been involved in four of PSG's past seven goals against Reims in Ligue 1 (two goals, two assists).

While goals had escaped him until last week, Mbappe has attempted (25) and completed (13) the highest tally of dribbles in Ligue 1 so far this term, as PSG look to extend an unbeaten run on the road in the league to 11 matches.

Kylian Mbappe has not asked to leave Paris Saint-Germain and will be involved in Sunday’s trip to Reims, head coach Mauricio Pochettino said.

Mbappe has been heavily linked with a blockbuster move to Real Madrid during this transfer window.

According to widespread reports, Madrid have offered €170million plus €10million in add-ons to sign the 22-year-old, who is in the final year of his contract with PSG.

Mbappe, who has scored 133 times in 174 games for the French giants, trained on Saturday ahead of the clash with Reims.

Pochettino also revealed that Lionel Messi and Neymar would play a part at Stade Auguste-Delaune.

"They will certainly all be in the squad, so we will see if they are in the starting 11 tomorrow," the head coach said.

"Kylian Mbappe is working very hard and is preparing for tomorrow's game.

"In terms of communications with our president and sporting director, they have made it clear what the club's stance is in this regard."

When asked whether Mbappe had expressed his desire to leave the club, Pochettino replied: "No."

PSG have made a 100 per cent start to the Ligue 1 season, winning all three of their matches so far.

Goalkeeper Gianluigi Donnarumma said he has not joined Paris Saint-Germain to sit on the bench, but will "stay humble" in his bid to oust Keylor Navas. 

Donnarumma left Milan upon the expiration of his contract at the end of June, subsequently joining Ligue 1 giants PSG on a free transfer.

The 22-year-old – who made his Milan debut at the age of 16 in 2015 – is one of five recruits PSG have made this transfer window, including Lionel Messi.

After making 30 Serie A appearances in 2015-16, Donnarumma missed just five league games for Milan over the past five campaigns, establishing himself as one of the world's best goalkeepers.

He only helped his reputation at Euro 2020, playing a starring role as Italy won the competition – indeed, Donnarumma made two saves in the penalty shoot-out victory over England in the final on July 11.

However, he has found himself starting the 2021-22 campaign behind Navas having been an unused substitute in the first game he was available for - a 4-2 win over for PSG over Brest last Friday.

"I came to Paris to play. PSG sought me and wanted me. And I wanted PSG,” Donnarumma told Canal Plus.

"I came here to play, so I will give my best to be a starter, but there must be competition. I am ready to play.

"I want to become one of the best goalkeepers in the world and in order to do that, it’s necessary to sacrifice and be humble. Being humble is the most important thing."

Donnarumma's switch to Paris has raised some questions given Costa Rica's Navas has shown himself a more-than-capable goalkeeper.

In Ligue 1 last term, excluding penalties and own goals, Navas let in 17 goals from an xGOT conceded total of 24.1, giving him a figure of 7.1 goals prevented.

Meanwhile, Donnarumma conceded 35 from an xGOT of 34.1, giving him a goals prevented figure of -0.9 in Serie A last season.

Navas might be feeling the heat, though, when he flapped at a relatively weak shot from Franck Honorat in the game against Brest when PSG were 2-0 up. 

Donnarumma insisted his rivalry with Navas, who has yet to keep a clean sheet in three Ligue 1 appearances this season, will be strictly a professional one and will not impact upon his relationship with his PSG team-mate.

"Competition doesn’t scare me. Keylor is a big goalkeeper, but I am here to play. The competition is good and can help us improve," Donnarumma added.

"There won’t be problems, Keylor is a great person, we are friends and there are no problems, competition is normal in big clubs."

The wait is over. A week-and-a-half after joining Paris Saint-Germain, Lionel Messi could be set to make his debut against Brest on Friday.

Following his shock exit from Barcelona as a free agent, Messi became the Ligue 1 giants' fifth major signing of the transfer window, joining the superstars Mauricio Pochettino already had at his disposal.

Messi, alongside his former Barca star Neymar, has been training this week, and though Pochettino refused to confirm his squad during Thursday's news conference, it is expected the duo will play a part.

With Kylian Mbappe already back, here's how Pochettino could set out at Brest.

GK: Keylor Navas

Navas has been one of Europe's outstanding goalkeepers in recent seasons, ranking third for goals prevented (8.1, using expected goals on target data) in the top five leagues in 2020-21. Gianluigi Donnarumma – the Player of the Tournament at Euro 2020 – did not leave boyhood club Milan just to sit on the bench and, at 22, represents the long-term option, but after only just returning to training, it is likely Pochettino will stick with the former Real Madrid goalkeeper for Friday's game, though the ex-Spurs boss did suggest Donnarumma may be available. 

RB: Achraf Hakimi

Alessandro Florenzi headed back to Roma at the end of his loan, but PSG identified just about the best replacement on the market. Over the previous two seasons, Robin Gosens (34) was the only defender with more goal involvements than Hakimi (30), who scored on his first Ligue 1 appearance.

CB: Marquinhos

PSG won 72.5 per cent of the games Marquinhos played last season in all competitions, conceding 0.7 goals on average. Those numbers altered significantly in his absence, with a winning percentage of 52.9 while shipping 1.1 goals per game. Even with the club's superstar signings, their captain remains one of the key men. Even though he has just returned from an extended break following Brazil's Copa America exploits, it would not be surprising to see the former Roma man thrown straight back into the fray given PSG have conceded three times across their opening two matches.

CB: Presnel Kimpembe

Sergio Ramos, another freebie, may no longer be able to play every game – he appeared only 15 times in LaLiga for Real Madrid last term – but PSG better hope he is there for the big ones. However, the 36-year-old will not be available until September, meaning France defender Kimpembe is likely to continue in the heart of defence for now. He made a game-high four clearances in last week's 4-2 home win over Strasbourg.

LB: Abdou Diallo

This is perhaps the one position on the pitch where PSG lack a genuine world-class option. Even if Pochettino were to bring in Kimpembe as a third centre-back, there is no outstanding left-sided wing-back. Diallo, a defensive full-back in an attacking team, gets the nod by virtue of starting the season fit and ahead of Layvin Kurzawa in the pecking order, while he also assisted Mauro Icardi's opener against Strasbourg.

CM: Ander Herrera

At the end of a season in which Marco Verratti was restricted to only 16 Ligue 1 starts, Euro 2020 provided a reminder of his talents. The Italy midfielder created a tournament-leading 14 chances across just five games while still completing 93.1 per cent of his 417 passes. However, it seems likely we will have to wait to see the playmaker link up with Messi, as he too is only just easing his way back into training. In his place, Herrera seems set to carry on in midfield and, in truth, is a more than able back-up. He attempted 100 passes on matchday two, completing 94 of them.

CM: Danilo Pereira

Leandro Paredes, Messi's international colleague, was trusted for the big occasions in the Champions League. However, he has just returned to training after helping Argentina win the Copa America, while Idrissa Gueye has been out due to COVID-19 protocols. Youngster Eric Ebimbe started against Strasbourg but was replaced by Pereira after an hour, and the towering Portuguese would add some presence in the middle of the park.

CM: Georginio Wijnaldum

Angel Di Maria would be very unfortunate to miss out on a full-strength XI and undoubtedly still has a part to play even with Messi in place, but he too is only just back from international duty. Wijnaldum has featured in both of PSG's Ligue 1 games so far and across his Liverpool Premier League career, led all Reds midfielders in recoveries (951) and duels won (645) and ranked second in interceptions (115) and third in tackles (181).

RW: Lionel Messi

Of course, Messi can play across the front three, but starting from the right – with Hakimi in the Dani Alves role outside him – will bring back memories of Barca teams of old. It is the role he occupied in 2014-15, forming part of perhaps the Blaugrana's most exciting attacking trio, which of course Neymar was also part of.

CF: Kylian Mbappe

Mbappe has the Luis Suarez role, providing the direct runs in behind that create space in front of the defence for Messi and Co, and a video of the two stars linking up in training went viral this week. Last season's 53 goal involvements did not quite match the forward's career-high of 54 in 2018-19, but Mbappe can expect to break all sorts of records in this thrillingly creative line-up this term. He already has two Ligue 1 assists to his name this season, and that is without playing alongside two of the world's best players.

LW: Neymar

Still the world's most expensive player if no longer the biggest name in his own dressing room, Neymar was the third member of that 2014-15 front three. Having decided to step out of Messi's shadow, the Brazil superstar wanted his old friend back. During their four years together at Barca, Neymar assisted Messi 22 times, while the six-time Ballon d'Or winner returned the favour on 20 occasions, and surely the chance to have this sensational front three starting together will be too tempting for Pochettino to turn down – even if it is harsh on the in-form Icardi.

Paris Saint-Germain coach Mauricio Pochettino insists he did not hear the jeers directed at Kylian Mbappe before and during Saturday's 4-2 Ligue 1 win over Strasbourg.

Mbappe – making his 150th Ligue 1 appearance – was a leading light for PSG at the Parc des Princes, getting an assist for Julian Draxler and also finding the net via a massive deflection off Ludovic Ajorque in the first half.

He was a regular threat to the Strasbourg defence but will likely be frustrated not to have added more goals as he was denied by Matz Sels twice in the second period.

Despite consistently being the biggest danger in a PSG side that faded badly in the second half and saw their 3-0 lead cut to 3-2, Mbappe was targeted by certain sections of the crowd.

The France international is into the final year of his contract at the club, and although president Nasser Al-Khelaifi said Mbappe had no reason not to extend his deal following the signing of Lionel Messi, an agreement still eludes PSG as Real Madrid circle.

However, Pochettino is convinced Mbappe remains utterly focused.

"Kylian is focused on our goals. He did well and I am very happy with his performance. He must continue like this," said Pochettino.

"I didn't hear the whistles against Mbappe."

Earlier in the evening it was all cheers for the fans in the Parc des Princes, which welcomed a capacity crowd for the first time since February 2020. Those in attendance got their first glimpse of Messi following his arrival from Barcelona.

Messi and his fellow new signings – including former Real Madrid captain Sergio Ramos – were presented on the pitch before the game to a raucous ovation, though neither of those two actually played.

Pochettino wished he could have joined in the celebrations.

"It was a great day for the PSG family, there was an amazing atmosphere," Pochettino said.

"I was not present during the presentation of the signings, but the feedback we got was that it was incredible.

"All players need to feel this affection from the fans. I want to congratulate the whole club again. We experienced something moving. I would have preferred to be outside the changing rooms to experience this.

"It's always nice to see our supporters up close. Football is different with the public. A year and a half later, it feels good."

Lionel Messi will be given time by Paris Saint-Germain coach Mauricio Pochettino to regain his fitness before making his debut following this week's shock switch from Barcelona.

The six-time Ballon d'Or winner ended his 21-year association with Barca on Tuesday by penning an initial two-year deal at the Parc des Princes with the option of a third.

Messi has not played since helping Argentina to a 1-0 win over Brazil in the Copa America final on July 10 and has had just two training sessions with his new club.

PSG host Strasbourg at the Parc des Princes in their second Ligue 1 game of the campaign on Saturday, but Pochettino is not prepared to risk using Messi too soon.

"Today was his second training session since the Copa America final," Pochettino said at a pre-match news conference on Friday. "The priority for him is to feel better and better.

"Only then will we see if he is ready to play matches."

Messi departed Barcelona having scored 672 goals and assisted 265 more in 778 appearances for the cash-strapped Catalan giants across a 17-season stay in the first team.

The 34-year-old's arrival in the French capital has understandably dominated the headlines and Pochettino is just as excited as the PSG supporters with the high-profile signing.

"We share the same feelings that the fans are experiencing, a great positive energy," he said. "Every coach in the world wants to have the best players.

"It's nice to have a roster of excellent players here to increase competition and help us achieve our targets."

Questions have been raised as to whether PSG can keep the likes of Messi, Neymar and Kylian Mbappe on their books without breaching financial fair play regulations.

Mbappe is into the final year of his deal and has been linked with a move to Real Madrid, but Pochettino reiterated the club's stance that the World Cup winner is not going anywhere.

"He is one of our players and will continue to be our player," Pochettino said. "Our president has already said so and this is what counts."

Messi is not the only big name to join PSG in this window, with Sergio Ramos also signing on a free alongside Gianluigi Donnarumma, Georginio Wijnaldum and Achraf Hakimi.

However, ex-Real Madrid captain Ramos has yet to play for his new club due to a calf problem that will keep him out of action until after September's international break.

PSG provided the latest update on Ramos' fitness on their official website on Friday, while also confirming full-back Juan Bernat is back in full training.

Asked if integrating the former captains of rivals of Barcelona and Madrid into the same side will be a challenge, Pochettino replied: "They will be like brothers in a PSG shirt.

"It has been like the Big Brother house here this week with all the attention. But Leo has a great relationship with everyone and has had a good welcome."

The influx of more superstar players has only increased the pressure on Pochettino to reclaim the Ligue 1 title and win a first Champions League, a challenge that he is up for.

"It's no more or less responsibility than in other projects I've had at Espanyol, Southampton and Tottenham," Pochettino said.

"The responsibility here is to win games. If you don't, you're in trouble. The challenge is to make sure the stars that shine on their own can work well as a team."

PSG kicked off their Ligue 1 campaign with a 2-1 comeback win at Troyes last week.

The Parisiens are unbeaten in their 30 Ligue 1 home games against next opponents Strasbourg (W23 D7), a French top-flight record for one team at home to a specific opponent.

With question marks over the fitness of numerous players, Pochettino is unsure how he will line up on Saturday.

"Let's take it slowly. There are still things to be resolved in terms of who will play. That's something we will establish later," he said.

"The priority tomorrow is to win the game. We need to find the right balance between concentration and the general excitement that has surrounded the club for a few days."
