Paris Saint-Germain capped a busy transfer window with the loan signing of highly rated left-back Nuno Mendes from Portuguese champions Sporting CP, with Pablo Sarabia moving in the other direction.

Mendes joins PSG on a season-long loan, while the Ligue 1 giants have the option to buy the Portugal international at the end of the season.

The 19-year-old had previously been linked with the likes of Manchester City and Liverpool, but he has made the move to PSG alongside fellow recruits Lionel Messi, Sergio Ramos, Gianluigi Donnarumma, Achraf Hakimi and Georginio Wijnaldum.

A product of Sporting's famed youth academy, Mendes played a key role as the club ended their 19-year title drought last season.

The teenager amassed a total of 47 appearances across all competitions, scoring once and tallying three assists for Sporting, who also won the Taca da Liga in 2020-21.

Last season, Mendes ranked fourth in the league in expected assists (3.44), third in duels won (186) and second in dribbles attempted (88).

Mendes made two Primeira Liga appearances this term, leaving an unbeaten Sporting side second in the standings and two points adrift of rivals Benfica through four rounds.

He joins a PSG team that standing two points clear at the top of Ligue 1 with four wins out of four and craving a first Champions League triumph.

Spain midfielder Sarabia will spend the remainder of the season on loan with Sporting.

The 29-year-old has scored 22 goals and provided 12 assists for PSG since his move from Sevilla in 2019.

A whirlwind day last Friday saw Manchester United reach an agreement with Juventus to bring Cristiano Ronaldo back to the club.

The deal was confirmed just hours after it had looked likely the Portugal star would be heading to Premier League champions Manchester City instead.

According to reports, United manager Ole Gunnar Solskjaer encouraged the club to enter the race when it began to seem inevitable Ronaldo would head to the Etihad Stadium. Contact from Bruno Fernandes, Rio Ferdinand and even Alex Ferguson helped persuade Ronaldo that a return to Manchester could mean only one thing.

It all made for a short-lived but extraordinary transfer saga that ended with United re-signing a player who made history with the club between 2003 and 2009, winning three Premier League titles, the Champions League and the first of his five Ballons d'Or.

Here, Stats Perform looks at some other deals that caused a shock in the sporting world...

Lionel Messi: Barcelona to Paris Saint-Germain, 2021

In the most sensational free transfer of all time, PSG again laid down a marker to the football world with the signing of Lionel Messi on a two-year contract. Just as he looked to sign a new Barcelona contract, the club informed him that their dire financial situation meant they could not bring their greatest ever player back under LaLiga's salary restrictions after his previous deal expired in June. A tearful Messi said farewell to the only club he had ever played for before heading to the fanfare of Paris and a reunion with Neymar.

Neymar: Barcelona to Paris Saint-Germain, 2017

The Brazilian had formed a potent attacking trio with Messi and Luis Suarez at Camp Nou but a move to PSG was inevitable when the French side met his world-record buyout clause of €222million. He has played an important role in their continued dominance of French domestic football but has so far been unable to guide them to Champions League glory. He was reduced to tears by his side's 1-0 defeat to Bayern Munich in the 2020 final and then failed to inspire the team in the 2021 semis as Manchester City knocked them out.

LeBron James: Cleveland Cavaliers to Miami Heat, 2010

Basketball icon James announced he would sign with the Miami Heat instead of returning to his hometown team, the Cleveland Cavaliers. Then a two-time NBA Most Valuable Player and a six-time All-Star, James added to the spectacle of the stunning move by announcing it on a special television broadcast called The Decision. He enjoyed four years in Miami, where he won a pair of NBA titles, before returning to the Cavaliers in 2014. 

Tom Brady: New England Patriots to Tampa Bay Buccaneers, 2020

Few people expected Brady to leave the Patriots after 20 years and six Super Bowl victories. Not only did one of the game's greatest ever quarterbacks leave, but he joined one of the least successful franchises in NFL history and instantly guided them to glory, leading the Buccaneers to the franchise's second Lombardi Trophy with a 31-9 triumph over the Kansas City Chiefs in Super Bowl LV.

Luis Figo: Barcelona to Real Madrid, 2000

Should Messi ever return to Camp Nou as an opposition player it is unlikely he will be on the receiving end of the kind of abuse that greeted Figo. Barca fans threw bottles, lighters and even a pig's head at the Portuguese star when he went back to Camp Nou with Los Blancos in the seasons following his controversial move.

Wayne Gretzky: Edmonton Oilers to Los Angeles Kings, 1988

In 1988, the Edmonton Oilers and Los Angeles Kings agreed a deal that shook the NHL to its core. The trade left Canada in disbelief, with a member of the country's parliament even proposing the federal government block the trade or buy Gretzky's contract and sell it to another Canadian team. "The Great One" would go on to enjoy eight successful years in Los Angeles before spells with St. Louis Blues and New York Rangers.

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."

Crack open the bubbly. In France's City of Kings, at the heart of the Champagne region, Lionel Messi made his Paris Saint-Germain entrance as footballing royalty arrived in the 'farmers' league'.

There's a new king in town and although we saw only half an hour of Messi at Reims' Stade Auguste-Delaune, you could hardly take your eye off the man.

Incongruous in the blue of PSG as he was, this is Messi's lot now, the future he has chosen since his Barcelona career ended in a flood of tears.

Ligue 1 gets a rough rap but Messi's arrival instantly makes it box office, and those beholding this spectacle were given a peak into what we should expect.

There was a word in the ear from Mauricio Pochettino and then a hug for Neymar, as Messi replaced the world's most expensive footballer midway through the second half, moments after Kylian Mbappe scored his and PSG's second goal of what turned out to be a 2-0 win.

There was to be no Messi goal, as much as it appeared many inside the stadium were willing there to be one, particularly the pogoing PSG ultras.

His entrance and then his first touch, a simple 10-yard pass deep inside his own half, were cheered loudly, and it was not long before Messi was collecting the ball and charging forward, driving at pace through midfield and darting towards the penalty area.

Such a familiar sight, and here Messi had the luxury of being able to offload to Mbappe on the right. Mbappe, the player Real Madrid desperately want and might yet get before transfer window closes.

Then came notice from the union of Ligue 1 hardmen that Messi would not have it easy in France.

As Mbappe collected the pass, Messi was given the no-nonsense treatment twice by backtracking Reims players as he sought the return ball, Marshall Munetsi practically grabbing the six-time Ballon d'Or winner around the collar in a fruitless effort to halt his progress.

Mbappe could not quite pick the pass, with Messi surrounded, but it was a moment where you wondered what a rich harvest of goals that combination might produce, and whether we might see its potential come to fruition this season.

Munetsi hacked down Messi again later as the game reached stoppage time. Naturally, Messi has seen it all before. It was handshakes all round at the end.

It might be a different shirt, but this was the same old Messi. There was the thrill of one of those delicious give-and-go movements, and referee Francois Letexier played six minutes of stoppage time too. Why not see a little more?

Deep beneath the streets of Reims lie 200 kilometres of cellars and tunnels housing the finest bottles of bubbles, produced in these parts and maturing underground before being dispatched worldwide.

It pays to be patient, the subterranean conditions bringing the best out of the local delicacy before it reaches its fullest flavour. Bring a bottle out too soon and the product will fall short of the exacting standards 

Messi's 65 minutes on the bench allowed him to size up the pace of the French game at close quarters, and then he was ripe to be released. The cork is out of the bottle now though, and the thrill of Messi at provincial stadiums such as this is one fans will drink in for as long as this stop-off lasts.

He was fouled three times in all, a joint team high alongside Neymar, had 26 touches, and made 95.2 per cent of his passes (20 of 21). He won four of his five duels – those within the laws of the game – and no doubt delighted Pochettino and his Qatari paymasters.

PSG brought their imported grandes marques to a city that exports its homegrown fizzy finery, where the cathedral has witnessed 31 coronations, and they won with goals from a young player they might be dispatching to foreign climes within a matter of hours in return for a king's ransom.

Perhaps Mbappe might just fancy a full season of this, though. Will his partnership with Messi really be a one-night stand?

As jarring as watching this all unfold must have felt in Barcelona, as bitter an aftertaste as it must have left, all it lacked for the Parisians was the crowning glory of a Messi goal, and they will soon be flowing.

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.

Paris Saint-Germain president Nasser Al-Khelaifi dismissed the possibility of Cristiano Ronaldo joining fellow superstar Lionel Messi at the Ligue 1 giants, insisting "we haven't even thought about it".

Ronaldo is expected to leave Juventus before the transfer window closes, with the former Manchester United star reportedly in talks to sign for Premier League champions Manchester City in a stunning deal.

PSG have also been linked with the 36-year-old and five-time Ballon d'Or winner, who is in the final year of his Juve contract in Turin – where the Portugal captain arrived from Real Madrid in 2018.

The possibility of former Madrid and Barcelona foes Ronaldo and Messi joining forces in Paris has excited fans, but Al-Khelaifi slammed the door shut on the Portuguese forward moving to the French capital.

"We haven't even thought about it," Al-Khelaifi told beIN Sports.

Since turning 30 in February 2015, Ronaldo has been directly involved in 392 goals in 356 games for club and country.

Ronaldo has scored 263 goals and supplied 63 assists in 295 club appearances, while he has managed 57 goals and nine assists in 61 international fixtures during that period.

It comes as PSG star Kylian Mbappe looks to leave the club, with Madrid reportedly closing in on the France international.

Despite Mbappe being out of contract at the end of the season, Madrid are believed to have offered €180million.

Al-Khelaifi said: "The club's stance is clear, nothing has changed.

"Everything is still the same, we will not change [our stance] or repeat it."

Mbappe has scored 133 goals and provided 58 assists across 174 games over four years at PSG since arriving from Monaco.

The 22-year-old's 191 goal involvements since his debut rank third among players in Europe's top five leagues in that time, behind Messi (236) and Bayern Munich superstar Robert Lewandowski (213).

Mbappe was on target as Mauricio Pochettino's PSG overcame Brest 4-2 in Ligue 1 last week.

PSG's Mbappe scored his fourth Ligue 1 headed goal, his first with for club and his first since March 2017 with Monaco at Caen.

Mbappe has been decisive in eight consecutive Ligue 1 games (eight goals, three assists), his second-best run in the top-flight, behind February-November 2020 (10).

Pep Guardiola and Lionel Messi will go up against each other in the Champions League after Manchester City and Paris Saint-Germain were drawn into the same group.

Messi and Guardiola enjoyed a close relationship during their time together at Barcelona, but for the first time they will meet with neither of them representing the Catalans.

Six-time Ballon d'Or winner Messi left Barca at the end of June when his contract expired, and while he was expected to sign on with them again, the Blaugrana's hands were tied due to financial restrictions.

As such, Messi was swiftly snapped up by PSG despite previous links with City and a potential Guardiola reunion.

Another narrative could yet enter the conversation with respect to City versus PSG, as Juventus forward Cristiano Ronaldo – Messi's long-time rival – has been strongly with a move to the Etihad Stadium.

If Ronaldo does not leave Juve, he will go up against the holders Chelsea – who beat City in last season's final – in Group H.

There will be a repeat of the 2020-21 Europa League final in Group F as Manchester United have been offered the opportunity for revenge against Villarreal, who defeated Ole Gunnar Solskjaer's men in a remarkable penalty shoot-out in Belfast at the end of May.

Three of Spain's other representatives have tough groups to contend with: Barcelona were drawn with Bayern Munich, Benfica and Dynamo Kiev; Real Madrid will again face Inter and Shakhtar Donetsk as they did in 2020-21; and Atletico Madrid must go up against Liverpool, Porto and Milan.

Sevilla, on the other hand, are in the seemingly even Group G with Ligue 1 winners Lille, Salzburg and Wolfsburg, the latter of whom are back in the competition for only the third time.

First-time qualifiers Sheriff of Moldova joined Madrid, Inter and Shakhtar in Group D.

Group A: Manchester City, Paris Saint-Germain, RB Leipzig, Club Brugge

Group B: Atletico Madrid, Liverpool, Porto, Milan

Group C: Sporting CP, Borussia Dortmund, Ajax, Besiktas

Group D: Inter, Real Madrid, Shakhtar Donetsk, Sheriff

Group E: Bayern Munich, Barcelona, Benfica, Dynamo Kiev

Group F: Villarreal, Manchester United, Atalanta, Young Boys

Group G: Lille, Sevilla, Salzburg, Wolfsburg

Group H: Chelsea, Juventus, Zenit, Malmo

Lionel Messi is yet to play for Paris Saint-Germain this season, but has been called up to Argentina's squad for their World Cup qualifiers next month, with Paulo Dybala making a long-awaited return.

Having led Argentina to Copa America glory, Messi made the shock switch from Barcelona to Paris earlier in August, though he is yet to make his debut for Mauricio Pochettino's team.

The 34-year-old, along with fellow former Barca star Neymar, is expected to make his bow against Reims in PSG's final game before the international break.

Messi, along with club-mates Angel Di Maria and Leandro Paredes, would then travel to South America for matches against Venezuela, Brazil and Bolivia.

However, despite Pochettino having given his blessing for Messi to play for his country next month, this could result in the trio missing up to four of PSG's September fixtures.

Argentina and Brazil are both on the French government's 'red list' for travellers, meaning arrivals must quarantine for 10 days once they return to France, unless they have been fully vaccinated. It is unknown if the players in question have yet received both doses.

PSG face Clermont on the second weekend in September, with a tussle against Lyon following a week later. A 10-day quarantine period would mean Messi and team-mates would certainly miss those matches, as well as the opening round of the Champions League group stage, which is to be played on September 14 and 15, while an away trip to Metz in Ligue 1 could also come too soon.

Travel restrictions could well change in the coming weeks, though PSG will not be the only team fretting over possible mandatory quarantine for players in Lionel Scaloni's squad.

Premier League players Emiliano Martinez and Emiliano Buendia, both of Aston Villa, and Cristian Romero of Tottenham would have to isolate regardless of their vaccination status under the current travel restrictions imposed by the UK government.

Meanwhile, Juventus forward Dybala has earned a recall after almost two years out of the picture.

Dybala, who endured an injury hit 2020-21 but scored in Juve's 2-2 draw with Udinese on Sunday, last featured for Argentina in November 2019.

With Sergio Aguero and Mauro Icardi both unavailable due to injury, and Lautaro Martinez a doubt despite being included, Dybala has made the cut to round off Scaloni's attack.

Argentina squad in full:

Franco Armani (River Plate), Emiliano Martinez (Aston Villa), Juan Musso (Atalanta),Geronimo Rulli (Villarreal); Marcos Acuna (Sevilla), Juan Foyth (Villarreal), Lisandro Martinez (Ajax), Lucas Martinez Quarta (Fiorentina), Nahuel Molina Lucero (Udinese), Gonzalo Montiel (Sevilla), Nicolas Otamendi (Benfica), German Pezzella (Real Betis), Cristian Romero (Tottenham Hotspur), Nicolas Tagliafico (Ajax); Rodrigo De Paul (Atletico Madrid), Nicolas Dominguez (Bologna), Alejandro Gomez (Sevilla), Giovani Lo Celso (Tottenham Hotspur), Exequiel Palacios (Bayer Leverkusen), Leandro Paredes (Paris Saint-Germain), Guido Rodriguez (Real Betis); Julian Alvarez (River Plate), Emiliano Buendia (Aston Villa), Angel Correa (Atletico Madrid), Joaquin Correa (Lazio), Angel Di Maria (Paris Saint-Germain), Paulo Dybala (Juventus), Nicolas Gonzalez (Fiorentina), Lautaro Martinez (Inter), Lionel Messi (Paris Saint-Germain).

Lionel Messi was the topic of plenty of speculation in recent weeks before inking a two-year deal with Paris Saint-Germain.

The 34-year-old left Barcelona as a free agent after two decades with the Catalan club, unable to stay despite wanting to continue his career there.

But rumours are swirling already about Messi's next move after PSG, even though he has yet to even make his debut for the Ligue 1 side.

TOP STORY - BECKHAM HOLDS MESSI TALKS

Inter Miami owner David Beckham has held talks with Messi about joining the MLS club after his PSG contract expires, reports The Mirror.

The former Manchester United and Real Madrid midfielder has promised to bring a superstar player to the club, with links to Cristiano Ronaldo in the past.

According to the report, Messi purchased six luxury penthouse apartments in Miami a few weeks ago, adding fuel to the fire.

ROUND-UP

- Manchester City will need to up their bid for Harry Kane to Tottenham by £50million to convince Spurs to sell, reports The Mirror. City have reportedly tabled an improved bid since their £100m offer and are said to be willing to go as high as £120m.

- Newcastle are ready to make a move to sign Everton's Colombian midfielder James Rodriguez, according to fichajes.net.

- Milan are interested in a move for Manchester City midfielder Bernardo Silva for £45m (€52m) according to Star on Sunday.

- The Sun claims that Southampton are looking to complete a bargain deal for Celtic midfielder Ryan Christie, who is out of contract at the end of the season.

Lionel Messi will not make his Paris Saint-Germain debut against Brest on Friday after being left out of the travelling squad.

Messi has been training this week alongside former Barcelona team-mate Neymar, but neither have made the group for PSG's third Ligue 1 match of the season.

The wait for free signing Messi's PSG bow will now extend at least until next week's trip to Reims, the club's final match before the first international break of the 2021-22 campaign.

Mauricio Pochettino has still been able to call upon a stronger, more experienced squad than in previous weeks, though.

Euro 2020 Player of the Tournament Gianluigi Donnarumma is included for the first time since his own free transfer from Milan, although he has competition from regular goalkeeper Keylor Navas.

Club captain Marquinhos, midfielder Marco Verratti and creator Angel Di Maria are also all back involved again.

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.

Lionel Messi and Neymar have been training together for Paris Saint-Germain, but Mauricio Pochettino refused to comment whether the pair would feature against Brest.

PSG travel to Brest on Friday fresh from back-to-back Ligue 1 wins against Troyes and Strasbourg, the first time in three years they have begun a new domestic season in such fashion.

Despite a positive start to their campaign, interest continues to centre around Messi, who arrived in Paris after a shock exit from Barcelona amid the club's financial difficulties in August.

However, it remains unclear whether the highly anticipated pairing of Messi and Neymar will be reunited to form a formidable trio with Kylian Mbappe at Stade Francis-Le Ble.

"We haven’t decided the squad yet but we will do so shortly," Pochettino responded in Thursday's news conference when asked about Messi.

"We will analyse whether he can be in the squad. In terms of what Lionel Messi brings, everybody knows that.

"His presence here in terms of what he represents is something we have talked about a lot in recent days.

"I am pleased with how he has settled in and how he has connected with squad. When you have talent at this sort of club, the understanding is not just in the dressing room but also on the pitch."

As part of a fearsome frontline with Luis Suarez at Barcelona between 2014 and 2017, Messi and Neymar between them created 2.1 chances for one another per 90 minutes, resulting in 22 assists for the duo.

But, like Suarez when he moved to Barcelona, it is Messi who will have to quickly link-up with an already established pairing, Mbappe and Neymar.

Neymar's injury troubles have meant that he and Mbappe have only played 3,552 minutes together – less than half as many as Messi and Suarez – though they have combined for 102 chances (2.6 per 90) and 21 assists (one every 169 minutes).

However, as with questioning over Messi's inclusion, Pochettino kept his cards close to his chest as to whether Neymar would feature.

"As I said, we are assessing that and of course, we take physical and footballing attributes into account," the head coach reiterated. "Within the squad, we have to find the right balance."

Mbappe, who is the only player to have recorded more than one assist following a ball carry in Ligue 1 this term (two), is the third part of Pochettino's forward puzzle, but his future remains in question.

With just a year left on his current deal, links to Real Madrid were expected to be quashed by Messi's arrival as the Frenchman realises his opportunity to challenge for Champions League glory at the Parc des Princes.

"I think he [Kylian Mbappe] is very motivated and working hard ahead of this season," the former Tottenham boss added. "We are thinking the same things we have been thinking in recent weeks. He is our player and I want him to be here this season."

"The most important thing is Kylian Mbappe is calm and knows what he is doing. He knows what he wants to do. We know that he is our player. We want him to be here.

"My conversations with Kylian Mbappe are all about football. He has another year on his contract and even if he doesn’t renew, he is still a PSG player and we are pleased with him, and from what I understand, he is pleased with us."

Real Madrid star Toni Kroos appeared to tease the possibility of Kylian Mbappe joining the LaLiga giants following Lionel Messi's move to Paris Saint-Germain.

Mbappe continues to be linked with a blockbuster transfer to Madrid as he enters the final year of his PSG contract and the France international is no closer to signing a new deal.

PSG have no intention of selling Mbappe, who was jeered by sections of the crowd before and during Saturday's 4-2 Ligue 1 win over Strasbourg.

With Barcelona great and six-time Ballon d'Or winner Messi now in Paris, Kroos mischievously suggested his presence in the French capital could lead to Mbappe's departure.

"We will see how everything goes [regarding the signing of Messi to PSG]," Kroos said on Einfach mal Luppen – a podcast he runs with his brother.

"The move may be good for us because our biggest rivals have lost their best player.

"And something even better may come out of it as a consequence. Maybe a player from Paris [Saint-Germain] will join us... I don't know."

Mbappe was on target as Mauricio Pochettino's PSG overcame Strasbourg, with the World Cup winner having now either scored or assisted in seven consecutive matches in Ligue 1 (eight goals, four assists).

It was Mbappe's 150th Ligue 1 appearance – in the past 40 seasons, only Zlatan Ibrahimovic (113) scored more goals in his first 150 games than the Frenchman (108).
