Bayern Munich's sporting director Hasan Salihamidzic believes Robert Lewandowski's return to the club in the Champions League with Barcelona will not be a "distraction".

The Poland international departed the Bundesliga champions during the transfer window, bringing an end to a trophy laden eight-year spell in Bavaria.

Lewandowski has quickly settled into life in his new surroundings, scoring nine goals in six games for Barca in all competitions – including a hat-trick in the Champions League victory against Viktoria Plzen last week.

All eyes are now firmly focused on the midweek clash between Bayern and Barca in Munich, but Salihamidzic is not worried about the prospect of Lewandowski affecting the preparation of Julian Nagelsmann's team, though he admitted better performances are required after a run of three straight Bundesliga draws.

"We have to go up one or two more gears. Even three. We need to play much better against Barca than we are currently doing," he told Sport.

"Barca have top-level players with Lewandowski at the helm and they will take advantage of every opportunity.

"We don't think Robert's return can be a distraction, we don't think so."

Bayern conceded a last-gap equaliser on Saturday against Stuttgart, Matthijs de Ligt giving away a penalty, while Barca swept aside Cadiz in a 4-0 win.

Robert Lewandowski has paid tribute to "great champion" Iga Swiatek following his compatriot's US Open triumph.

Swiatek became the first Polish singles champion at Flushing Meadows after defeating Ons Jabeur in straight sets on Saturday.

It was the world number one's second grand slam success of a brilliant season, having won a further six WTA titles including the French Open in June.

The 21-year-old became the first woman to triumph at Roland Garros and Flushing Meadows in the same campaign since Serena Williams in 2013.

Swiatek and Lewandowski are among the pre-eminent Polish sports stars of this generation and shared an embrace on Court Philippe Chatrier following the former's success in Paris.

The Barcelona striker, who was on target in the Blaugrana's 4-0 win at Cadiz this weekend, celebrated his compatriot's latest victory, hailing the 10th WTA title of her career on social media.

"Congratulations Iga!" he tweeted. "You're a great champion, and you've proven it yet again on the biggest stage. I am so happy for you."

Robert Lewandowski continued his brilliant start to life in LaLiga to help seal a 4-0 win for Barcelona at lowly Cadiz, though a medical emergency in the crowd marred Saturday's match.

Introduced by Xavi just after Frenkie de Jong's first goal of the season had put Barca ahead in Andalusia, Lewandowski slid in to wrap up the points.

It marked Lewandowski's sixth LaLiga goal in his fifth appearance in the competition, with no player having managed as many goals in their first five games in Spain's top flight in the 21st century.

Yet a routine win was soured in the closing stages, with play halted and the players taken off the field following a medical emergency in the stands.

When the match eventually resumed after a 40-minute delay, Lewandowski turned provider for Ansu Fati and Ousmane Dembele scored as Barca saw out a rout that moves them top of LaLiga with four wins from their five games.

Cadiz relied on the woodwork coming to their rescue in the 10th minute, when Raphinha's low effort hit the right-hand post.

Raphinha blazed over from Barca's next chance, with Memphis Depay showing a similar lack of composure after connecting with Ronald Araujo's knockdown.

De Jong tried a cheeky lob early in the second half, but it never came close to testing Jeremias Ledesma. Yet after a warning shot from Fede San Emeterio at the other end, the Barca midfielder was presented with a simple chance.

It was one he took, thumping a first-time finish into a gaping net after Ledesma had parried Gavi's cutback.

On from the bench, Lewandowski needed just eight minutes to put the game to bed – the 34-year-old's poacher's instincts on show as he tucked in a loose ball from a yard out.

The match was already over as a contest, but Barca added two more after the restart, with Lewandowski squaring for Fati to tap in before Dembele's shot squirmed home.

Bayern Munich head coach Julian Nagelsmann believed his side "absolutely deserved the win" as they beat Inter 2-0 at the San Siro to kick off their Champions League campaign.

A brilliant first-half goal from Leroy Sane set the German champions on their way to victory, before a Danilo D'Ambrosio own goal as he clumsily tried to block a Sane shot killed the game off.

The Bundesliga side saw out the remaining minutes to earn a clean sheet and all three points to make it 11 games unbeaten against Italian teams in the Champions League, as they look for their first European title since the 2019-20 season.

And Nagelsmann was delighted with his team's performance, telling reporters: "I'm happy with the performance today. We had a good intensity throughout the 90 minutes.

"In both halves, we had a spell of 10 minutes where we gave the opponent space and our opponents can obviously play.

"But overall we absolutely deserved the win. It was important to start with three points.

While Nagelsmann was pleased with his players, he believes there is much work to be done as they hunt for trophies.

"I enjoy it when we win. But there are many areas of improvement, we want to exploit them and we will try to do it on a daily basis."

Elsewhere in Europe, former Bayern striker Robert Lewandowski scored a hat-trick as his new side Barcelona opened up their Champions League group stage with a 5-1 thrashing of Viktoria Plzen.

Lewandowski returns to the Allianz Arena next week as his old and new teams face off, and Nagelsmann says he hopes the fans give him a good reception despite his somewhat acrimonious departure.

When asked about facing him, Nagelsmann added: "I am looking forward to it, yes. Not so much to facing him, because he is very dangerous in front of goal.

"But as a person I will be pleased to see him. I hope the fans will honour that too, regardless of how things were with his departure."

Barcelona coach Xavi is overjoyed by Robert Lewandowski's start at the club, referring to him as "insatiable" after terrorising Viktoria Plzen.

The 34-year-old was in ruthless form on Wednesday, scoring a hat-trick as Barca thrashed their visitors 5-1 at Camp Nou.

Playing his first Champions League game for Barca, Lewandowski netted two sumptuous 20-yard strikes either side of a stooping header, with the hosts comfortable throughout.

Wednesday's treble ensured Lewandowski became the first player to net a Champions League hat-trick for three clubs, having scored four for Bayern Munich and one with Borussia Dortmund.

But Lewandowski's display was not a real shock given his strong start to life in LaLiga, and everything about his first few weeks at Barca has left Xavi amazed.

"Robert is like that, he's insatiable. I'm delighted with how he trains, how he improves the team," Xavi told Movistar.

"He's humble, he expects [of his team-mates] and he does a great job of pressing.

"It's not just the hat-trick anymore, it's his work and how he dominates."

Lewandowski was not the only Barca player to impress, however – had the Pole not scored a hat-trick, most would have seen Ousmane Dembele as the standout performer.

The France international was dazzling at times on the right flank.

It was only the second time in a Barcelona shirt that Dembele has laid on five key passes in a single game, and two of those resulted in assists.

Dembele was in devastating form in the second half of last season, and Xavi feels the winger is having fun at Camp Nou.

"He is happy, enjoying himself," the coach added. "He is a player who makes a difference – he assists and scores goals. He is a dagger down the wing."

Barcelona's three first-half goals on Wednesday ensured they have already scored more than the two they managed in the whole group stage last term.

But a tricky trip to face Bayern Munich at the Allianz Arena awaits next week.

Robert Lewandowski made history with his maiden hat-trick for Barcelona against Viktoria Plzen, becoming the first player to hit Champions League trebles for three different sides.

The Poland international found the target twice in the first half at Camp Nou on Wednesday, with Franck Kessie and Plzen's Jan Sykora also netting in a frantic opening 45 minutes.

Lewandowski capped a scintillating performance with his third after 67 minutes, firing a 20-yard finish past Jindrich Stanek after a neat interchange with Ferran Torres, who then struck to seal a 5-1 victory for Barca.

The latter strike for Lewandowski made him the first player to ever score Champions League hat-tricks for three different teams, having previously hit trebles for Bayern Munich (four) and Borussia Dortmund (one).

Lewandowski was level on Champions League goals with Karim Benzema (86) heading into the game but moved to third in the all-time scoring charts – only Lionel Messi (125) and Cristiano Ronaldo (140) have more.

The Barca forward has been in fine LaLiga form as well, scoring five times in four league appearances, and will look to continue his scoring run when the Blaugrana visit Cadiz on Saturday.

Robert Lewandowski scored his first Barcelona hat-trick as the Blaugrana met expectations with a dominant 5-1 win over Viktoria Plzen to open their Champions League campaign.

Barca's three first-half goals were more than they managed over the whole group stage last season (two) when they were dumped into the Europa League, though sterner challenges await.

Plzen had moments against an unconvincing Barca defence, with Jan Sykora netting just before the break, but the hosts were already ahead thanks to Franck Kessie and Lewandowski, who made it 3-1 on the stroke of half-time.

Although the tempo slowed slightly, Barca remained dominant after the break and Lewandowski ensured he became the first player to net a Champions League hat-trick with three different teams before Ferran Torres got in on the act.

Barca deservedly went in front early when Jules Kounde's header from a corner set up Kessie to nod in on his first start for the club.

Plzen looked set to level when Andreas Christensen clumsily tripped Jhon Mosquera in the box, but a foul on the Dane was spotted following a VAR review.

That reprieve was added to soon after as Lewandowski ruthlessly found the bottom-right corner from 20 yards.

Plzen at least appeared to be going into the break within touching distance thanks to Sykora converting from close range, but the excellent Ousmane Dembele teed up a stooping Lewandowski header to swiftly restore the two-goal lead.

Ansu Fati surprisingly sliced well wide in the first minute of a second half that was significantly less intense, but his wastefulness mattered little.

Lewandowski increased the deficit and cap his hat-trick with another sumptuous 20-yard finish after a neat interchange with Torres.

The Spain winger then rounded things off with a thumping strike from Dembele's cross.

What does it mean? Barca starting to right wrongs

Barcelona's Champions League campaign last season was dreadful – while they were paired with Bayern Munich in the group, they also finished below Benfica. Dynamo Kiev were the only team they beat.

Granted, their group this season is even tougher given Bayern and Inter are the other two teams Barca will face, but this was clearly a much greater showing than they produced against anyone in 2021-22. This was not a season-defining showing by any stretch, but the fact Barca made it look so straightforward at least shows progress.

Dembele ouses class

Lewandowski will obviously hog most headlines with his exceptional treble, but Dembele was still the best player on the pitch.

His five key passes – and two assists – were match highs, but he was just an absolute terror in general. A tremendous display.

Fati finding his feet

Xavi has been patient with Fati this season following his injury woes. This was his first start of the campaign and there was certainly some rustiness on show, as one might expect.

None of his four shots were on target, though Barca will be happy to see him come through the game unscathed, and he was lively in the first half.

What's next?

Barca go to Bayern next Tuesday as Lewandowski returns to the Allianz Arena, while Plzen will host Inter the same day.

Simone Inzaghi set Inter a 10-point target for their daunting Champions League group as Hakan Calhanoglu warned of the danger of shipping more gift goals.

A sleepy Inter defensive display saw the Nerazzurri toss away an early lead to lose 3-2 to Milan in Saturday's Serie A derby, with goalkeeper and captain Samir Handanovic having an off day.

While that is a recent concern, Calhanoglu pointed the finger at costly errors in Champions League games against Real Madrid and Liverpool last season.

A 1-0 group-stage home defeat to eventual champions Madrid was tough to take after Inter missed a host of chances before leaking an 89th-minute Rodrygo goal; then another dominant display at San Siro against Liverpool in the first knockout round proved worthless as two late goals gave Jurgen Klopp's team one foot in the quarter-finals.

Inzaghi's team face Bayern Munich in a tricky opener on Wednesday, and with Barcelona also in Group C, along with likely whipping boys Viktoria Plzen, the battle for places could be fierce. Only the top two go through to the knockout rounds.

Inter have home advantage for the first meeting with Bayern, and Inzaghi said: "We have to score 10 points in this group. which is objectively very difficult even compared to last year. But we are Inter and facing Bayern is an opportunity: they are one of the three to four candidates to win the trophy."

Last season saw Inter scrape together 10 points from their six group games, but the opposition, along with Madrid, was provided by Shakhtar Donetsk and Sheriff.

This time around it looks tougher to plot a route to double figures.

Midfield playmaker Calhanoglu said: "Last year, we dominated against Real Madrid and Liverpool. We had the games in our hands but lost due to small mistakes that changed the way they went.

"We need to be more focused and united on the pitch. We've analysed our mistakes and are ready. This year, we're in another difficult group, but this is what the Champions League is like. It's great to be involved and play against strong sides to see what point we're at."

In the Bundesliga, Bayern have drawn consecutive games against Borussia Monchengladbach and Union Berlin. This might be the time to face them, though Bayern have often punished teams in the past who thought that way.

"I have seen Bayern's last two games," said Inzaghi. "In terms of numbers, there has been no competition. The opponents have been good at limiting them with continuous aggression. Bayern have such intensity and aggressiveness as to be one of the best teams in Europe."

Inter and Bayern have met seven times in European competition, both sides winning three apiece, with one draw. Inter got the better of Bayern in the 2010 Champions League final on neutral ground at the Santiago Bernabeu, but the Germans have a 100 per cent winning record in away games in Italy in the rivalry (W3).

Bayern's Sadio Mane could become the fourth African player to reach 25 goals in the Champions League. He is currently one away, looking to join illustrious company in Didier Drogba (44), Mohamed Salah (36) and Samuel Eto'o (30).

The former Liverpool forward came in effectively to replace Robert Lewandowski, ahead of the Pole transferring to Barcelona.

Having to face both in the group stage will test Inter's fragile backline, but Inzaghi is backing his players.

"We met Mane already last year, he is a great player with a crazy intensity," Inzaghi said. "Lewandowski is another great player. In a month and a half we will meet them both: they are very difficult but very stimulating matches."

Xavi believes Barcelona can end an eight-year wait for Champions League glory this season as he told his players to "dream" of lifting the trophy.

The head coach sends his side into their opener against Viktoria Plzen on Wednesday, desperate for them to avoid a repeat of the last campaign's group-stage exit.

Barcelona finished behind Bayern Munich and Benfica, with Xavi appointed midway through that group campaign after Ronald Koeman was sacked.

The serious damage had been done by a 3-0 loss at Benfica, and Xavi could not drag Barcelona through to the knockout rounds.

However, he has had two busy transfer windows since then and Barcelona are a new-look and refreshed team, with much of their previous baggage shaken off.

Last season's failure in Europe inevitably hurt more when Barcelona's great rivals Real Madrid went on to beat Liverpool in the final, but Xavi wants to move on.

"The main target now is to get through the group stage," said Xavi, "then we'll see.

"Dreaming is free so why can't we win this competition? But we have to start by taking the three points tomorrow."

Xavi was a substitute in the final of the 2014-15 Champions League when Barcelona beat Juventus 3-1 in Berlin, thanks to goals from Ivan Rakitic, Luis Suarez and Neymar.

Now directing matters from the touchline, he is reluctant to predict how Barcelona will fare, but says there is no harm in having lofty goals.

"We are going to compete and dream of winning the Champions League, otherwise I wouldn't be here," Xavi said. "I want to win. We have to be very humble. Since 2015 we haven't won the Champions League and last year we went into the Europa League.

"You have to think that every game is going to be a war. We have had a very difficult group."

With Bayern and Inter alongside Barcelona and Plzen in Group C, Xavi's remark certainly stands up to scrutiny. Although it may not play out this way, Plzen will be seen as the team the big three must beat, before thrashing out the top places.

Xavi spoke highly of Plzen's counter-attacking qualities, but anything other than three points at Camp Nou would be majorly anti-climactic.

"This is the Champions League and we want to start well. It is the most difficult group in recent years, but we want to go through and reach the last 16," Xavi said.

The Barcelona boss will look towards Robert Lewandowski to propel the Catalans through to the knockout rounds, after his previous success for Bayern in the competition.

Lewandowski has scored more goals than any other player in the Champions League across the last three seasons, with 33 goals in 26 games.

Should he score against Plzen, it would make him only the third player to score for both Barcelona and Bayern in the competition, after Mark van Bommel and Philippe Coutinho.

Lewandowski netted nine goals in five home games for Bayern in the Champions League last season, which might augur well for Wednesday.

Xavi will be without Miralem Pjanic, with the midfielder bound for Sharjah FC, and is set to make changes from the side that beat Sevilla 3-0 in LaLiga on Saturday.

"There will be rotation," Xavi said, confirming the likes of Jordi Alba and Ansu Fati could step up from their weekend substitute roles. "There is tiredness and discomfort. The match against Sevilla was a war.

"Let's compete in the Champions League and dream of winning it. In our history we have won it five times. We'll try to compete to go as far as we can."

Erling Haaland has revealed he felt "sorry" for Robert Lewandowski after Bayern Munich attempted to sign the Norway international from Borussia Dortmund.

Haaland joined Manchester City from Dortmund in July after being linked with the majority of the biggest clubs in Europe.

Bayern played down reports they wanted the striker as a successor to Poland captain Lewandowski, who got his wish to join Barcelona.

Speaking in the documentary Haaland: The Big Decision, City's prolific frontman stated that he felt uncomfortable over talk that he could join Bayern while Lewandowski was still with the Bundesliga champions.

"If I try to imagine how Lewandowski thinks... I don't know how many goals and titles he has for the club," he stated.

"Then I do actually feel a little sorry for him. At the same time it's a chance for him to take the next step in his career.

"It feels disrespectful, but at the same time it is an opportunity for him."

Haaland has made a blistering start to life at City, with 10 goals in his first six Premier League appearances, while Lewandowski has scored five in four LaLiga games for Barca.

Robert Lewandowski scored his fifth goal in three LaLiga games and Raphinha opened his Barcelona account in a 3-0 victory over fragile Sevilla.

Raphinha opened the scoring with a simple header and Lewandowski capitalised on Sevilla's defensive frailties to double Barca's lead in the first half.

Eric Garcia got in on the act with his first senior goal in the second half and Jules Kounde provided two assists against his former club on his return to the Ramon Sanchez-Pizjuan, where Barca cruised to a third consecutive victory.

Angry Sevilla fans turned voiced their disapproval during a defeat that leaves them with just one point from four matches.

Sevilla made a promising start and Marc-Andre ter Stegen produced an excellent one-handed save to deny Ivan Rakitic when the former Barca midfielder went one-on-one with the goalkeeper after some slack defending.

The Blaugrana sparked into life and produced a devastating counter-attack to take the lead after 21 minutes, with Fernando clearing off the line after Lewandowski dinked the ball over Yassine Bounou but only onto the head of Raphinha, who could not miss from point-blank range.

Lewandowski made Los Rojiblancos pay for leaving him unmarked nine minutes before the break, taking a pinpoint pass from Kounde on his chest and volleying inside the bottom-left corner with his right foot.

Kounde somehow failed to add a third against his former club when he headed wide unchallenged from only five yards out with Sevilla all at sea at the back.

Defender Kounde turned provider for a second time early in the second half, heading Raphinha's delivery from the right across goal unmarked to give Garcia a tap-in.

Bounou showed sharp reflexes to keep out another Lewandowski volley after Sergi Roberto picked the striker out with a whipped cross from the right.

Lewandowski failed to chip Bounou when he was sent clear again as the busy keeper stood tall and stuck out a palm and Frenkie de Jong was unable to finish following up on a painful evening for Julen Lopetegui's struggling side.

Barcelona head coach Xavi heaped praise upon "natural leader" Robert Lewandowski, highlighting other aspects of his game beyond the goals after the 4-0 win against Real Valladolid.

The recent acquisition from Bayern Munich scored a brace for the second game in a row to take his tally to four in three games and was unfortunate to have not secured a hat-trick, hitting the frame of the goal twice.

Lewandowski's goals were always going to be the most valuable outcome of his lucrative transfer, but Xavi believes he offers more than his devastating impact in the final third.

"Apart from the goals, I would highlight his timing. Everything that the fan does not see so much, is extraordinary," he told DAZN.

"He is a natural leader; what he sees he says. It's wonderful how he has adapted to the group. He is a born worker, an example."

Having started the campaign with a goalless draw against Rayo Vallecano, Barcelona have secured back-to-back wins against Real Sociedad and Real Valladolid, scoring eight goals in the process – more than any other side to have completed three matches.

While Xavi made it clear there are areas for improvement, he hailed the team for a "remarkable" performance.

"Perfect no, but it was a great match. The first 40 minutes were very good. Then we relaxed. In the second part we started well as well," he added.

"Overall, it was a perfect match, but not a complete one. You don't have to relax and you have to keep squeezing. We wanted to give back to the fans the illusion. 

"This is good for the team and for the fans. We should not relax as has happened with the 2-0. I have to watch the game repeated but there are things to improve. There is no perfect match, but it was remarkable."

Barcelona's next test is against Sevilla before commencing their Champions League campaign, having been handed a tough group that includes Bayern Munich and Inter.

Robert Lewandowski struck a brace for the second game in a row as Barcelona strolled to a comfortable 4-0 win against Real Valladolid.

The game saw Jules Kounde make his long-awaited debut for the club following his move from Sevilla, having had his registration postponed, but it was another of Barcelona's marquee additions who stole the show.

Poland international Lewandowski struck in both halves of Sunday's contest at Camp Nou, a poacher's finish at the far post for his first and a deft backheel for his second.

Pedri and Sergi Roberto were also on the scoresheet for Xavi's side, who stand unbeaten in LaLiga with seven points from a possible nine.

The hosts started strong but were foiled by the frame of the goal, Lewandowski heading into the post before Ousmane Dembele smashed a ferocious effort against the crossbar.

A breakthrough came after 24 minutes, though, Lewandowski on hand at the far post to stab home Raphinha's inviting cross.

It was two before the break, Pedri finding space around the penalty spot to comfortably steer Dembele's pass beyond the helpless Jordi Masip.

Barcelona's dominance continued in the second period, boasting 66 per cent possession on the hour mark, and, while fans had to be patient for a third goal to capitalise on their dominance, it was worth the wait.

Dembele cut inside from the right to tee a pass through to Lewandowski, who expertly backheeled a finish past his marker and the keeper – taking his tally to four goals in three matches for his new side.

Lewandowski was denied a hat-trick in stoppage time, striking the frame of the goal from close range, but Sergi Roberto was on hand to tuck away the rebound.

Barcelona head coach Xavi is "pretty sure" defender Jules Kounde will make his LaLiga debut for his new team against Real Valladolid this weekend.

Kounde joined Barca from Sevilla for a reported fee of €55million this transfer window, after the Catalan club beat Chelsea to the France international's signature.

However, Barcelona's financial situation meant Kounde could not be registered to play in LaLiga, although other new arrivals Robert Lewandowski, Raphinha, Franck Kessie and Andreas Christensen have each made their debuts.

But Xavi believes the situation is finally sorted and is confident Kounde will feature against Valladolid at Camp Nou on Sunday.

Xavi told reporters at his pre-match news conference: "It's a negotiation with LaLiga. We are pretty sure that Jules can play tomorrow. We are optimistic."

Kounde is sure to be a big help for Barcelona in Europe as they compete to lift their first Champions League trophy since beating Juventus in the final in the 2014-15 campaign.

Xavi's team will first have to get out of a tricky Group C that includes Inter and Viktoria Plzen, as well as Bayern Munich, who infamously thumped Barcelona in a humiliating 8-2 defeat in the 2019-20 quarter-finals.

And Xavi knows the size of the task ahead of his team, saying: "It's a very difficult group, perhaps the toughest. 

"We've made very good signings this season, we've invested a lot. The Champions League and the league, we want to go through and fight for the trophies. But the challenge is massive. It's perhaps the group of death."

Robert Lewandowski will be reunited with Bayern Munich in the Champions League on September 13, with Erling Haaland facing former side Borussia Dortmund the following day.

Following his move to Barcelona in July, Lewandowski is set for a swift reunion with Bayern after the European heavyweights were drawn together in Group C.

The same can be said for Haaland, who departed Dortmund for Group G opponents Manchester City.

Lewandowski will return to the Allianz Arena on matchday two; 24 hours before Haaland and City welcome Dortmund to the Etihad Stadium, with the return fixture at Signal Iduna Park taking place on October 25.

Reigning champions Real Madrid launch their title defence away at Celtic on September 6, though the standout fixture of the opening day sees Paris Saint-Germain and Juventus lock horns at the Parc des Princes.

The following day sees last season's finalists Liverpool begin their quest to go one step better away at Napoli, whose Serie A rivals Inter meet Bayern at San Siro.
