The more things change, the more they stay the same.

So that proved in Tuesday's Champions League clash at the Allianz Arena, a match billed as Robert Lewandowski's reunion with Bayern Munich, the club he left for Barcelona in a €50million deal just two months ago.

Yet in the end, the Poland international failed to make the impact many had predicted on his return to Bavaria, on a night of disappointment for Barca against opponents they must simply hate the sight of.

Two goals in the space of four minutes early in the second half from Lucas Hernandez and Leroy Sane proved the difference between the sides as Bayern made it five wins in a row against the Catalans by an aggregate 19-4 scoreline.

Going further back, this was Barca's ninth Champions League loss to Bayern, which is now more than twice as many as they have suffered against any other opponent in the competition (four v Milan, Paris Saint-Germain and Chelsea).

Julian Nagelsmann had called on his Bayern side to "put on a show" amid growing doubts over his own future on the back of three successive league draws, Bayern's longest wait for victory in the Bundesliga in four years.

For 45 enthralling minutes, the hosts were second best and rather grateful that their former hero Lewandowski had stage fright on his first trip back to this ground.

The prolific striker had five shots alone in the first half, which was one more than the entire Bayern side, equating to an expected goals (xG) return of 0.5 compared to 0.3 for the hosts.

Lewandowski would have expected to capitalise during his time at Bayern – he scored 344 times in 375 appearances for the German giants – but this proved to be a rare off-day.

He also failed to get his head on Joshua Kimmich's delightful corner that was instead met by Hernandez for the opening goal of the contest. At that point, Barca had conceded 16 goals from the past 30 shots on target faced against Bayern in the Champions League.

That soon became 17 goals from 31 shots on target thanks to Sane's goal after the winger was played in by the ever-improving Jamal Musiala, who himself would not look out of place in the Barca side Xavi is desperately attempting to mould.

Going down 2-0 to Bayern is far from irreparably damaging from Xavi's perspective, even if it does end an unbeaten start to the season spanning six matches. If ever there was a game to truly gauge how far his side have come this season, this was very much it.

It was only a little over nine months ago that Xavi described a 3-0 loss in this fixture as "a harsh reality" for his side. Just weeks into the job, the club legend acknowledged Europa League-bound Barca could not consider themselves among Europe's elite clubs at that point.

The performance produced by Barcelona in the first half on Tuesday offered plenty of promise. They may not be back at their very best just yet, but the signs of improvement on the back of a busy transfer window are clear to see.

And while this game did not quite follow the script from Lewandowski's perspective, the former fan favourite – who finished the match with seven attempts and an xG of 0.8 – will have a second chance to inflict some pain on his old side when they face off again at Camp Nou next month.

Yet on the basis of this latest tussle between the heavyweight clubs, it seems no matter what ploy Barca take – even if that means nabbing their opponents' best player – the outcome will remain the same. Now that is a harsh lesson.

Simone Inzaghi was in no doubt as to the importance of Inter's 2-0 Champions League win at Viktoria Plzen, as he looks to navigate a path through a group containing Barcelona and Bayern Munich.

Having fallen to a 2-0 loss against Bayern last Wednesday, Inter were faced with the prospect of starting a Champions League campaign with back-to-back defeats for just the second time (after doing so in 2006-07).

But Edin Dzeko's cultured first-half finish put the Nerazzurri in control, and Denzel Dumfries made the points safe after Pavel Bucha was dismissed on the hour mark.

Inter have now won three of their last four Champions League away games, as many as they had in their previous 12 such matches.

Having triumphed 1-0 at Liverpool in the second leg of a last-16 tie in March, meanwhile, the Nerazzurri have won back-to-back away games in the competition for the first time since October 2011. 

Inzaghi, who began his news conference by labelling Barcelona and Bayern "the two best teams in the world at the moment", was aware of the importance of taking maximum points in the Czech Republic.

"We know we will face them, today the goal was to bring home the points," he said.

"We made easy a match that was not, no Italian team had won here in Plzen. It's a well-deserved victory, wanted by the boys, I'm happy.

"We are happy, because we knew that the opponent could not be underestimated. We knew the path of all the Italian teams that came here in Plzen. 

"The boys were good, they remained focused, and I congratulated them in the locker room."

Inter never looked likely to surrender the points after Dzeko swept into the bottom-right corner. The former Manchester City and Roma striker has now recorded 20 goal involvements in his last 21 Champions League appearances (14 goals, six assists).

While praising the forward's contribution, Inzaghi highlighted the importance of competition in the Inter attack as he revealed Romelu Lukaku should return from injury after this month's international break.

"Edin was good, like all his team-mates. I need everyone in defence, in midfield and in attack," he added.

"After the break Lukaku will return, and from match to match I will choose the attacking couple who will enter the field."

Plzen coach Michal Bilek, meanwhile, rued the ruthlessness of the Bosnia and Herzegovina international, declaring: "I said yesterday that a shot on goal was enough for him to score.

"He is a very good player and even today he managed to score like this. For the rest of the match I think that our players managed to control him well."

Joel Matip was the Liverpool hero as his thumping late header handed the Reds a much-needed 2-1 win over Ajax at Anfield on Tuesday.

The defender secured three priceless Champions League points with his 89th-minute heroics, a huge relief for boss Jurgen Klopp after last week's 4-1 humbling by Napoli.

Mohamed Salah earlier ended a seven-game goal drought in the competition to nudge Liverpool ahead, but Ajax were level before the half-hour mark as Mohammed Kudus capped a 26-pass spell of possession.

Ajax went close through Daley Blind late on, but Matip was more precise as his header crossed the line despite Dusan Tadic's desperate attempts to keep it out. 

The hosts edged ahead in the 18th minute as Alisson's kick reached Luis Diaz, who found Diogo Jota. From a central position, Jota fed the eager Salah, who lashed past Remko Pasveer and into the bottom-right corner.

Diaz and Jota went close as Liverpool threatened to add to their opener, but the Reds were caught out by a rapid Ajax break down the left, which culminated with Kudus' sublime finish into the top-left corner. 

Pasveer saved well from Virgil van Dijk's header, and then denied Trent Alexander-Arnold twice in quick succession before the interval.

Both Van Dijk and Matip then headed over the crossbar from set-pieces as Liverpool kept up the pressure after the break, but Blind almost stunned Anfield from Tadic's right-wing cross when he nodded a foot wide of the right-hand post. 

Liverpool Substitute Darwin Nunez shot wide with seven minutes remaining, but Matip came good with time running out, rising to meet Tsimikas' corner and power the ball towards goal.

While Tadic nodded away, the former Southampton man was was a foot behind the line when doing so, and the relief inside Anfield was obvious as the goal was awarded.

Bayer Leverkusen scored twice in the last seven minutes to condemn Atletico Madrid to a 2-0 defeat in the Champions League.

A scrappy clash at BayArena appeared to be heading for a stalemate until Robert Andrich broke the deadlock when he swept past Ivo Grbic.

And Moussa Diaby then rounded off a quickfire counter to secure Leverkusen’s first points on the board in Group B on Tuesday.

There were familiar frustrations for Atletico, who have now lost seven of their last eight Champions League away matches in Germany.

Robert Lewandowski's return to Bayern Munich was not a fruitful endeavour as a wasteful Barcelona were swept aside in a 2-0 Champions League defeat.

Second-half goals from Lucas Hernandez and Leroy Sane condemned Xavi's side to yet another loss in Bavaria, a historically poor hunting ground for the Catalan giants.

Barcelona were unable to capitalise on a dominant first half, with Lewandowski spurning some fine opportunities, while Pedri struck the post after the visitors had fallen two behind.

A fightback never appeared likely, with Bayern producing a stellar display in the second period after a frustrating first 45 minutes.

After an end-to-end start, Barcelona looked the more threatening, with Pedri forcing Manuel Neuer to make a smart save and Lewandowski passing up a chance on the volley.

Lewandowski, ever the threat, then saw a header from close range saved well, while Raphinha dragged a low shot wide from outside the box.

Marc-Andre ter Stegen was belatedly called into action early in the second half as Leon Goretzka tested his compatriot from distance, and the resulting corner provided the breakthrough.

Joshua Kimmich's delivery to the near post was met by the head of Hernandez, escaping Marcos Alonso's attention and applying contact ahead of Ter Stegen.

And the lead was doubled four minutes later when Jamal Musiala fed Sane, who raced away and poked a deft finish into the net.

Pedri clipped the upright after a one-two with Lewandowski created space in the area, yet that was as close as Barca would come on another difficult night.

Antonio Conte did not believe Tottenham deserved to lose to Sporting CP but suggested their late collapse was a reminder of the limited room for error in the Champions League.

Tottenham were below par in their Group D encounter but looked set to settle for a share of the spoils at Estadio Jose Alvalade. 

However, Paulinho's 90th-minute header from a near-post corner and a fine individual goal from Arthur Gomes gave Sporting a win that puts them in control of the group on six points.

Spurs now have plenty of work to do in a pair of games with Eintracht Frankfurt after falling to a result Conte did not view as reflective of their performance.

"I think the game in the first half was in balance between the two teams," Conte told a media conference. 

"Honestly, in the second half, we felt the opportunity to get the three points and win the game. We had the chances to score, but in the end we are talking about a loss.

"For sure, we can do much better in those last few minutes. We conceded a counter-attack with a one-versus-one. It was the player who shot and Hugo [Lloris] made a really good save, maybe the most difficult save of the game.

"After this, the corner we conceded a goal. I always say to my players that the details move the final result. I think that maybe we didn't deserve to win, but at the same time we didn't deserve to lose this game tonight.

"We try to analyse the game very well with the players to understand what were the positive things that we did and what are the negative situations that we can improve for the future.

"For sure, this level is a high level, the Champions League. Against Marseille was another tough game. Tonight was another tough game. We need to know that if we want to have the ambition to go to the next round, we have to fight, we have to fight a lot, especially in this group, because in this group I see a lot of balance between the teams.

"The Champions League level is high. You know that you have to reduce the mistakes because in the end you can pay. Tonight we paid a lot.

"Now we are talking about a loss, a loss against a team that showed they are used to playing this competition. It's a pity, and we have to analyse the game well, and all the players they know very well that this level is an important level.

"It's right to continue to improve this process. Don't forget that last season we lost against Mura in the Conference League, and I think we made an important step forward."

A small minority of Liverpool fans interrupted a pre-match silence to honour Queen Elizabeth II ahead of the Champions League game against Ajax.

Liverpool legend Kenny Dalglish had urged all supporters to respect the silence after the Hillsborough Survivors Support Alliance made a similar plea.

Some in Liverpool hold strong anti-monarchy views, but the club had hoped those represented among their fanbase would manage to respect a short silence before Tuesday's fixture.

Sporadic shouting at Anfield began with a "Liverpool, Liverpool" chant that was hushed by many other supporters, and the silence was halted after 25 seconds by referee Artur Manuel Soares Dias.

It had not been specified as a minute's silence, with Liverpool describing it on their website ahead of the game as "a period of silence".

The Premier League club laid a wreath at the stadium to mark the death of the long-reigning monarch, while captain Jordan Henderson signed an official book of condolence in the city.

Bayern Munich defender Bouna Sarr has confirmed he will miss Senegal's World Cup campaign after undergoing surgery on his left knee.

The 30-year-old has struggled with the problem for the past couple of years, restricting him to just 12 appearances for Bayern last season and none in the 2022-23 campaign.

Sarr started all seven of Senegal's games in their Africa Cup of Nations triumph earlier this year, but the versatile right-sided player will play no part for his country in Qatar.

"I don't know how to express my disappointment to be away from the pitch for the coming months and especially to miss a World Cup," Sarr, capped 13 times, posted on Instagram.

"It was not an easy decision to make, but after many months of thinking, I understood it would be the wisest, and above all the most reasonable, decision for the rest of my career."

Sarr joined Bayern from Marseille in October 2020 and has played 27 times for the German giants in all competitions, 10 of those being starts.

Robert Sarver, the owner of the Phoenix Suns and the WNBA's Phoenix Mercury, has been suspended by the NBA for one year and fined $10million after an investigation found he engaged in racist and sexist conduct at the workplace. 

The report was published Tuesday and was initiated after the NBA commissioned a law firm to investigate Sarver's behaviour after ESPN reported last November allegations of racism and misogyny during his 18 years with the Suns.  

The investigators interviewed 320 people, and Sarver, team management and employees "cooperated fully with the investigative process", according to the NBA. 

The investigation found Sarver ''repeated or purported to repeat the N-word on at least five occasions spanning his tenure with the Suns,'' though added there is "no finding that Sarver used this racially insensitive language with the intent to demean or denigrate", concluding he said the word "when recounting the statements of others".

The study also determined that there were "instances of inequitable conduct toward female employees," including "sex-related comments" and inappropriate comments made toward a pregnant woman. 

He also made inappropriate jokes about sex and anatomy, as well as yelled and cursed at employees in a manner that would be considered bullying ''under workplace standards".

Based on the findings by the probe, the NBA punished Sarver by banning him from any NBA or WNBA team facility, including any office, arena, or practice facility; attending or participating in any NBA or WNBA event or activity, including games, practices or business partner activity; representing the Suns or Mercury in any public or private capacity; or having any involvement with the business or basketball operations of the Suns or Mercury. 

The league said it would donate his $10m fine ''to organisations that are committed to addressing race and gender-based issues in and outside the workplace".

''The statements and conduct described in the findings of the independent investigation are troubling and disappointing,'' NBA Commissioner Adam Silver said in a statement.

"We believe the outcome is the right one, taking into account all the facts, circumstances and context brought to light by the comprehensive investigation of this 18-year period and our commitment to upholding proper standards in NBA workplaces.'' 

Sarver said he will ''accept the consequences of the league's decision'', though also stated he disagreed with some of the investigation. 

"While I disagree with some of the particulars of the NBA's report, I would like to apologize for my words and actions that offended our employees," Sarver said in a statement through the Suns.

"I take full responsibility for what I have done. I am sorry for causing this pain, and these errors in judgment are not consistent with my personal philosophy or my values."

As part of his punishment by the NBA, Sarver will have to complete a training programme ''focused on respect and appropriate conduct in the workplace."' 

''On behalf of the entire NBA, I apologize to all of those impacted by the misconduct outlined in the investigators' report," Silver said. "We must do better."

T.J. Watt could return to action sooner than expected after the Pittsburgh Steelers refused to put a timescale on his absence beyond the Week 2 clash with the New England Patriots.

The reigning NFL Defensive Player of the Year winner suffered a torn pectoral in the fourth quarter of a wild 23-20 overtime opening victory over the Cincinnati Bengals.

According to NFL Network' Ian Rapoport, Watt tore a muscle but not the tendon, which could mean his absence is as short as six weeks. There had been concerns Watt's season could be over already.

The prospect of Watt avoiding surgery will be welcome in Pittsburgh, where Steelers head coach Mike Tomlin also pointed to positive news regarding the pass rusher.

Tomlin has yet to add Watt to the injured reserve list and said: "We're not in hurry to gather information too quickly. We will see how his body responds, we'll get second and third opinions and then at the end of the week or at some point we will do what's appropriate."

He added: "I can definitively say that T.J. won't play this week, but I won't make any commitments beyond that."

The clash with the Patriots takes place on Sunday, by which time the picture regarding Watt's likely return should be clear.

Watt shared an image on social media on Tuesday of Arnold Schwarzenegger's famous "I'll be back" catchphrase, from the Terminator movie. That has been interpreted as the 27-year-old suggesting his season is not over.

Tomlin further explained Pittsburgh's stance, adding: "Let me say this, we're probably in a lot better place than we were after the game and usually that's the case.

"That's why I don't always say too much after the game, even though there might be speculation out there."

Tottenham crashed to defeat in their Champions League encounter with Sporting CP as a stunning late show condemned them to a 2-0 defeat in Lisbon.

Spurs had produced a largely uninspiring performance at Estadio Jose Alvalade and appeared happy to settle for a share of the spoils.

But there was a twist in the tale in the closing stages when Paulinho turned home a corner at the near post in the 90th minute.

Sporting then made sure of the points in the third and final minute of injury time as Arthur doubled their tally with a superb individual effort on his debut.

Edin Dzeko and Denzel Dumfries guided Inter to a much-needed 2-0 win over 10-man Viktoria Plzen, kick-starting the Nerazzurri's Champions League campaign.

Defeat to Bayern Munich last Wednesday meant Inter needed to respond in the Czech Republic, and they never looked likely to drop points after Dzeko swept home in the first half.

Pavel Bucha's straight red card cemented Inter's superiority, with Dumfries making the points safe when Dzeko turned provider with 20 minutes remaining.

With Simone Inzaghi's men facing criticism after an inconsistent start to the season, the win provides a welcome boost ahead of the daunting prospect of back-to-back meetings with Group C rivals Barcelona.

Inter needed just 20 minutes to turn their dominance of possession into a deserved lead - Dzeko tucking a neat finish into the bottom-right corner.

Dzeko could have had a second when Marcelo Brozovic slipped him through on goal, but the forward's low effort was well saved by Jindrich Stanek.

Plzen were unable to test Andre Onana despite improving before the break, and were indebted to Stanek for saving Milan Skriniar's glancing header at full stretch three minutes into the second half. 

Dumfries missed a golden chance when he nodded over the crossbar from six yards out, but Plzen's chances of a comeback were left in tatters by Bucha's reckless challenge on Nicolo Barella, which saw him receive his marching orders following a VAR review.

The depleted hosts were put out of their misery in the 70th minute, Dumfries making amends as he latched onto Dzeko's pass and lifted a finish beyond Stanek.

What does it mean? Nerazzurri off the mark

Inter's meek defeat to Bayern led to an apology from chief executive Giuseppe Marotta, and the presence of two European heavyweights in Group C meant the Nerazzurri were under genuine pressure ahead of the trip to Plzen.

But Inzaghi's side produced the goods to boost their qualification hopes, ensuring Inter have still only started one Champions League campaign with back-to-back losses (under Roberto Mancini in 2006-07) in the process.

Dzeko steps up

With Romelu Lukaku injured and Lautaro Martinez starting on the bench, Inter's back-up strikers were handed an opportunity to shine on Tuesday.

Dzeko became the oldest player to play a Champions League game for Inter for over a decade last time out (since Javier Zanetti v Marseille in March 2012), but his cultured finish demonstrated the former Manchester City and Roma striker still has the quality to contribute.

Since Dzeko joined Inter in August 2021, only Martinez (28) has bettered his tally of 19 goals for the club in all competitions.

No joy for Plzen 

Few would have held out any hope for Viktoria Plzen after they were drawn into a group containing Inter, Barcelona and Bayern, and their back-to-back defeats have done little to reverse perceptions of them being Group C whipping boys.

Plzen have shipped 51 goals in just 20 Champions League matches, becoming just the second side to bring up an unwanted century in so few games; Malmo conceded their 50th Champions League goal in their 18th outing.

What's next?

Inter travel to Udinese for their next Serie A outing on Sunday, while Plzen host Slavia Prague in the Czech First League.
