Jude Bellingham’s dream start to his Real Madrid career continued after he fired home a stoppage-tine winner against Champions League debutants Union Berlin at the Santiago Bernabeu.

The hosts looked destined to be heading for a frustrating goalless draw after failing to find a way past the resilient Bundesliga side.

But England international Bellingham converted from close range with virtually the last kick of the Group C clash to claim his sixth goal in as many matches and land all three points for Carlo Ancelotti’s side.

Harry Kane scored from the penalty spot in Bayern Munich’s 4-3 win against Manchester United.

Absentee-hit United began brightly enough at the Allianz Arena, only for Serge Gnabry to score shortly after former Manchester City forward Leroy Sane’s effort squirmed past summer signing Andre Onana.

Rasmus Hojlund scored his first goal for the club, but Kane quickly slammed a penalty, with Casemiro scoring either side of Mathys Tel’s stoppage-time strike as the Red Devils suffered a fourth defeat in five matches.

In Group A’s other fixture, Galatasaray scored two late goals in a 2-2 draw against 10-man Copenhagen.

The Danish side went 2-0 at half-time through Mohamed Elyounoussi and Diogo Goncalves. Elias Jelert was sent off in the 73rd minute for two bookable offences and Galatasaray took advantage with Sacha Boey and Tete earning a point.

Arsenal enjoyed a fine return to the Champions League as they cruised past PSV Eindhoven at the Emirates Stadium.

Six years of absence were brushed to one side as a scintillating attacking display saw Bukayo Saka, Leandro Trossard, Gabriel Jesus and Martin Odegaard all score in a one-sided 4-0 win.

The result puts Arsenal top of Group B after Angelo Fulgini cancelled out Lucas Ocampos’ opener as Lens secured a 1-1 away draw at Sevilla.

In Group D, Lautaro Martinez salvaged a 1-1 draw at Real Sociedad with a 87th-minute equaliser following Brais Mendez’s early goal, while Red Bull Salzburg cruised to a comfortable 2-0 win at 10-man Benfica.

Karim Konate missed a third-minute penalty for Salzburg before Antonio Silva was sent off 10 minutes later. Roko Simic scored from the resulting spot-kick and Oscar Gloukh wrapped up the points.

Elsewhere, Sikou Niakate put through his own net with just two minutes remaining as Napoli secured a late 2-1 victory at Braga. Napoli captain Giovanni Di Lorenzo opened the scoring in first-half stoppage time before Bruma headed home a deserved equaliser in the 84th minute.

Lautaro Martinez’s late equaliser rescued disappointing Inter Milan a 1-1 Champions League draw against Real Sociedad at the Estadio de Anoeta.

Last year’s beaten finalists Inter had failed to have a single shot on target in their opening Group D tie when captain Martinez fired home in the 87th minute.

Brais Mendez had given Sociedad an early lead but the Spaniards, back in the Champions League for the first time since 2013-14, were cruelly punished after twice hitting the woodwork.

Inter thrashed city rivals AC Milan 5-1 on Saturday, but were a shadow of the side which have won their first four Serie A matches.

Sociedad lost 2-1 at Real Madrid on Sunday and have won only one of their first five LaLiga games, but went straight on the offensive.

Ander Barrenetxea had already hit the crossbar before Inter defender Alessandro Bastoni slipped in possession, allowing Mendez a free shot on goal, which he buried.

Marko Arnautovic headed Inter’s best chance before the break wide, but Sociedad went close to extending their lead.

Robin Le Normand’s diving header from Takefusa Kubo’s excellent cross flew inches over the bar and the impressive Kubo forced Inter goalkeeper Yann Sommer into a low save just before half-time.

Sommer made an even better save early in the second period to keep out Mikel Oyarzabal’s header as Sociedad chased another goal.

Le Normand’s header was blocked before Inter were given a reprieve in the 65th minute after referee Michael Oliver had shown Inter’s Nicolo Barella a straight red card.

The Italy midfielder appeared to stamp on goalscorer Mendez, but Oliver rescinded his decision after being asked to check the pitchside monitor by VAR.

Mikel Merino then headed another cross from Kubo against the bar for Sociedad as Inter failed to pose an attacking threat.

Simone Inzaghi’s side had mustered one attempt on goal throughout the game when they thought they had equalised.

Carlos Augusto side-footed home Alexis Sanchez’s low cross into the area in the 79th minute, but his effort was ruled out for offside.

But in the 87th minute the Italians levelled it up with their first shot on target.

Martinez raced on to Davide Frattesi’s low diagonal ball into the box and lifted a superb first-time shot over Sociedad goalkeeper Alex Remiro.

Manchester United’s Champions League return ended in disappointment as Harry Kane struck from the spot for Bayern Munich in an entertaining 4-3 win kicked off by Andre Onana’s clanger.

The European heavyweights are at very different stages right now, with the perennial Bundesliga champions second favourites to win a competition that the Red Devils did not even feature in last season.

Absentee-hit United began brightly enough at the Allianz Arena, only for Serge Gnabry to score shortly after ex-Manchester City forward Leroy Sane’s effort squirmed past summer signing Onana.

Rasmus Hojlund scored his first goal for the club but Kane quickly slammed home a penalty, with Casemiro scoring either side of Mathys Tel’s stoppage-time strike as the Red Devils suffered a fourth defeat in five matches.

Few could argue with the eventual outcome, but United had started brightly in Bavaria and should have gone ahead through Facundo Pellistri or Christian Eriksen inside four minutes.

Bayern, who were without suspended boss Thomas Tuchel on the touchline, shook off initial sluggishness, with Sane’s strike beating distraught Onana before Gnabry fired home four minutes later.

Hojlund’s effort off the heel of Kim Min-jae shortly after half-time brought hope to Erik ten Hag’s men, only for Eriksen to soon be adjudged to have handled.

Ex-Tottenham team-mate Kane scored the resulting spot-kick, with Casemiro’s brace sandwiching Tel’s strike during a dramatic conclusion to the Group A opener.

Arsenal enjoyed a fine return to the Champions League as they cruised past PSV Eindhoven at the Emirates Stadium.

Six years of absence were soon brushed to one side – as were PSV – as a scintillating attacking display saw Bukayo Saka, Leandro Trossard, Gabriel Jesus and Martin Odegaard score in a dominant 4-0 win.

The club’s hiatus from the top table of European football was so long someone felt it necessary to print the words to the Champions League anthem in the matchday programme and Arsenal’s players were certainly singing from the same hymn sheet.

Mohamed Elneny, back on the bench for the first time since a serious knee injury in January, was the only member of the current crop to have experienced Champions League football in an Arsenal shirt.

It did not take any of the tournament debutants long to make their mark on a new stage, however, as Saka struck inside eight minutes before Trossard doubled the lead, Jesus added a third before the break and Odegaard capped off a fine evening.

David Raya retained his place in the Arsenal goal having replaced Aaron Ramsdale for Sunday’s Premier League win at Everton.

Kai Havertz and Jesus came in for Fabio Vieira and Eddie Nketiah while Trossard deputised for the injured Gabriel Martinelli.

Saka set the tone for the evening, the England winger finishing after PSV goalkeeper Walter Benitez pushed an Odegaard shot into his path.

Jesus should have doubled the lead moments later but could not make contact on Ben White’s low cross but the second came soon after as the Brazil forward led a counter-attack and played in Saka, who crossed for Trossard to strike.

It was one-way traffic at the Emirates as Havertz fired over before Jesus forced Benitez into a good stop and then got on the scoresheet himself with a fine effort from a deep Trossard cross.

With Arsenal hosting north London neighbours Tottenham on Sunday, boss Mikel Arteta took advantage of the big lead to take off his key men as the second half progressed.

All three goalscorers, as well as Oleksandr Zinchenko, were replaced before the 70-minute mark with the Gunners in complete control of proceedings at a rain-soaked Emirates.

There was still time for more goals, Odegaard not to be outdone as he angled home a fine finish to further widen the gap.

Under Arsene Wenger, Arsenal progressed from the group stages of the Champions League for 17 successive seasons, but the last seven of those ended in defeat in the last 16.

Arteta’s team have started Group B in fine style but the Spaniard will be under no illusions that his side will face more challenging tests if they are to go deep into the competition and successfully juggle European football with a Premier League title bid.

Jude Bellingham’s fairytale start to his Real Madrid career continued after he fired home a stoppage-time winner against Champions League debutants Union Berlin at the Bernabeu.

The hosts, winners of the biggest prize in European football on 14 occasions, looked destined to be heading for a frustrating draw after failing to find a way past the resilient Bundesliga side.

But Bellingham converted from close range with virtually the last kick of the Group C clash to claim his sixth goal in as many matches following his summer transfer from Borussia Dortmund, and land all three points for Carlo Ancelotti’s side.

Los Blancos arrived for their opening Champions League fixture with a 100 per cent record in LaLiga to see them sit two points clear of rivals Barcelona after five matches.

Bellingham has been key to their strong start and the 20-year-old – the sixth English player after Laurie Cunningham, Steve McManaman, David Beckham, Michael Owen and Jonathan Woodgate to feature for Real in the European Cup – was again central to his side’s pursuit of a win under the lights.

After just three minutes it was Bellingham’s cross which Joselu nodded straight into the arms of Frederik Ronnow – the first of a hat-trick of headers he was unable to score during a tepid opening period.

Following the interval, Joselu then saw a header tipped on to the post by Ronnow.

Ancelotti’s men were starting to up the ante, and Rodrygo had two good opportunities to hand his side the lead – first drawing a good save from Ronnow, and then blasting an effort off the woodwork.

But as the clock ticked down, Real were staring down the barrel of a disappointing point with Ancelotti’s annoyance etched all over his face. That was until Bellingham saved the night.

Following Real’s 16th corner of a one-sided contest, Federico Valverde’s shot from the edge of the area was blocked, before falling perfectly into the path of Bellingham.

The unmarked England international could not miss as he prodded home from a little more than a yard out before wheeling away in celebration and lapping up the adulation of the adoring home crowd.

Julian Alvarez is revelling in his partnership with Erling Haaland in Manchester City’s attack.

The Argentinian World Cup winner continued his strong start to the season with two goals as the holders began their Champions League title defence with a comfortable 3-1 win over Red Star Belgrade on Tuesday.

An injury for Kevin De Bruyne has seen Alvarez handed a run of games in support of prolific centre forward Haaland and it is a role he is relishing.

“I am very happy with the goals, to help the team,” the 23-year-old said. “We are doing well, we are winning – which is the most important thing – and playing good games.

“I am trying to adapt and I continue growing in this position, where I am moving freely, to give the team another option and add to the attack.”

Alavarez was the dominant figure in City’s forward line as they threatened to overwhelm Red Star in their opening Group G game at the Etihad Stadium.

Yet despite creating a plethora of chances – with Haaland hitting the bar and goalkeeper Omri Glazer making several saves – City fell behind to an Osman Bukari strike just before half-time.

Alvarez began the fightback with a fine dinked finish after the restart and then put Pep Guardiola’s side ahead when his free-kick was inadvertently punched into the goal by Glazer.

Rodri wrapped up a thoroughly deserved victory with a typically composed finish 17 minutes from time but, again, City could have had several more. Haaland went the closest when he hit the goal frame for a second time.

“We played a good game,” said Alvarez. “It was important to start with a win and three points at home in this difficult competition. We are very happy.

“We had many chances we could not convert but Pep told us to keep doing what we were doing and the goals would come.

“It was the same in the previous game where we were losing and came back, so it was fine. We always try to stay calm, play well in the second half and win.”

Alvarez was not a regular starter last season, despite his starring role in his country’s World Cup triumph, but Guardiola believes he can do an important job in easing the goalscoring burden on Haaland.

Guardiola said: “It’s the same player as last season but being a World Cup winner doesn’t mean you have to play all the time.

“Last season we had Kevin and (Ilkay) Gundogan in that position. Kevin was in top form and Gundo was incredible.

“In that moment sometimes it was difficult to find spaces but I never had a doubt.

“Now Gundo has gone and Kevin unfortunately is injured. We need players to be close to Erling, don’t put all the responsibilities just on the shoulders of Erling to score all the goals.

“That’s why when Phil (Foden) has played there, when Julian plays there, we have the feeling that we create a lot of chances.”

Celtic goalkeeper Joe Hart will take confidence from their display with 11 men against Feyenoord as he and his team-mates seek to change their Champions League narrative.

The Dutch champions triumphed 2-0 in Rotterdam but Celtic’s hopes of a second-half comeback were dashed by red cards for Gustaf Lagerbielke and Odin Thiago Holm.

Hart saved a penalty in the five minutes between the red cards before being beaten again in the 76th minute.

The former England goalkeeper let in the opener from Calvin Stengs’ 30-yard free-kick in first-half stoppage-time after Celtic had more than held their own during the opening 45 minutes.

Celtic have now won just once in 22 Champions League group games and fans came away with similar frustrations to much of last season’s campaign, when their team’s two-point total was scant reward for some of their play.

When asked if it felt like the same old story, Hart said: “At the moment it feels like that but we are at the start of a new adventure. That’s the great thing about football, it always gives you a chance. This is a brand new season, whatever has been, has been.

“It’s a tournament of six games for us and we believe we put ourselves in a good position to play Feyenoord at home.

“Obviously we have got four other games that we need to take care of compete in. Now we know one of our rivals in this tournament, we feel like we can definitely compete with them.

“We had plenty of character, desire and buying into the messages that we are being given.

“We were in a good game, a close, close game and obviously a few things went against us, some of them self-inflicted, and you fall on the wrong side in this competition.

“But overall, 11 v 11, I felt like we could have given it a right good go.

“An avoidable goal just before half-time and two red cards makes it difficult.”

Hart described the opening goal as a “perfect storm” after the wall failed to do its job and then the ball curled just out of his grasp after skidding off the wet surface in Rotterdam.

“The guy running across Kyogo, causing Kyogo to move,” Hart said.

“”I have obviously got to hold my ground. As a goalkeeper you have got to hold your ground, especially when it’s very close to people’s shoulders, you’ve got to wait ’til it goes past them because you can’t over-commit.

“Once it went past Kyogo, I couldn’t get across quickly enough with the skip and the curl on the ball.

“It’s disappointing, obviously disappointing on my behalf, I’ve got high standards.

“But that doesn’t define the game, there was plenty more to come, and we were going toe to toe with a good team and it felt like we could have achieved something.”

Brendan Rodgers felt his Celtic team showed they can compete at Champions League level before inexperience played its part in their Group E opener against Feyenoord running away from them following two red cards inside five minutes.

Both Gustaf Lagerbielke and substitute Odin Thiago Holm were sent off on their Champions League debuts with Celtic trailing to Calvin Stengs’ 30-yard free-kick in first-half stoppage-time.

Joe Hart saved a penalty in between the red cards before Feyenoord went on to win 2-0 in Rotterdam.

Rodgers said: “We showed in the game that for this tournament we are going to be competitive.

“We started really, really well, for the first 60 minutes the game was very close. I thought we looked a threat and progressed the ball well into the final third. Maybe with better decision-making and releasing the pass we would have given ourselves the opportunity to get in front.

“I’m disappointed with the first goal, we should never be conceding that, especially at that moment.

“But it was even for 60 minutes and unfortunately we got two players sent off. It’s really difficult at this level with 11 against 11, but with 11 v nine, it’s difficult.

“But I have to applaud the players for their spirit and mentality, they kept going. It was harsh on them.”

Hart was left exposed by his wall for the opener, with Kyogo Furuhashi inadvertently jumping out of the way of the ball, and the curl on the shot took the ball away from the goalkeeper after it bounced on the wet turf, although he got a hand to it.

Rodgers said: “We talked about it inside. I like the players to make decisions and there was a decision within the game to change the wall. But you have to make sure the wall is correct or else you get done.

“It’s a very, very small detail but if you don’t look after it, you end up beaten. It was bitterly disappointing because we played well up to then.”

Rodgers felt both red cards should have been avoided. Lagerbielke received a second yellow after catching Igor Paixao in the throat with his arm as he tried to jockey the forward. Holm was shown a straight red card for lunging in to a high tackle.

Rodgers said: “With Gustaf, there was no drama. The ball was running through to the goalkeeper. I think it’s inexperience, just let the ball run through. I still thought it was a bit harsh but I can maybe see why the referee gave it. But we can avoid that situation for sure.

“The second one, he is young and committed but at this level you can’t go to ground. When I saw it back, his foot is up. At this level you get punished for that.

“Obviously they are bitterly disappointed afterwards, their first experiences of games at this level. They will learn from it.

“Gustaf had done well up to that point, two inexperienced centre-backs – I thought Liam Scales was outstanding and Gustaf had been coping well.”

Pep Guardiola felt his team were given a useful test after coming from behind to begin their Champions League defence with a 3-1 win over Red Star Belgrade.

The holders were stunned when the Serbian champions claimed a shock lead on the stroke of half-time through Osman Bukari in Tuesday’s Group G clash at the Etihad Stadium.

Yet as they did in the Premier League at West Ham last weekend, they hit back to win after the break, this time with two goals from Julian Alvarez and one from Rodri.

City manager Guardiola said: “At the end, going in at half-time 1-0, after what we’ve done that’s nice – after winning the treble we need to be the type of champions who prove to ourselves that we are able to make a comeback.

“In this situation it’s nice to prove it. In both games we played incredible and immediately at the start of the second half.

“We have things to improve in general but that’s really, really good.”

Guardiola was particularly impressed with the performance of his goalscorers.

Alvarez has benefited from a run in the side this season while Rodri, match-winner in last season’s final, continues to excel.

Guardiola said of Alvarez: “His movement was so quick and he’s so young. What a signing the club have done.

“He has everything – fighting, goals, assists. Incredible. And he’s a lovely guy. Playing behind Erling (Haaland) he is an incredible threat.”

Rodri has developed into one of the best midfielders in the game during his time at City and Guardiola is in no doubt he is now at the top.

He said: “Yes, he’s the best – but hopefully he can be better. He has a good mentality and good things to improve.

“But we were lucky again that the club has signed these type of players.”

The downside for City was the loss of Bernardo Silva shortly before half-time with an unspecified injury.

Guardiola said: “I didn’t speak with the doctors but apparently for the next games he will not be able to play.”

The Portuguese joins an injury list that includes Kevin De Bruyne, Jack Grealish, John Stones and Mateo Kovacic.

Guardiola said: “When we have five important players – really, really important players – injured, to sustain that for a long time will be difficult. But it is what it is.

“We cannot have the salaries and budgets for transfers to have 55 players. It would be chaos for the clubs and they would be bankrupt. Sometimes it happens.”

Red Star coach Barak Bachar admitted City were the better side.

He said: “We tried, we fought, but we conceded an early goal in the second half. They should have scored more.

“They are a great team, they have exceptional players. After we conceded it was difficult to maintain the pace, because we never play at this pace in our league. We learned a lot from this match.”

Lazio goalkeeper Ivan Provedel scored an equaliser deep in injury time as his side claimed a dramatic 1-1 draw with Atletico Madrid at the Stadio Olimpico.

The hosts looked to be heading for a narrow defeat in their opening UEFA Champions League Group E clash after Pablo Barrios fired the visitors into a 29th-minute lead.

But under instructions to go up for a corner in the fifth minute of added time, Provedel continued to loiter in the box before leaping to glance a Luis Alberto cross past his opposite number Ivo Grbic.

Provedel’s goal was the sixth by a goalkeeper in the Champions League and only the second from open play, after Sinan Bolat scored for Standard Liege against AZ Alkmaar in 2009.

There was also drama in the other Group E encounter as goals from Calvin Stengs and Alireza Jahanbaksh saw Feyenoord claim a 2-0 win over Celtic, who finished the game with nine men.

Stengs’ free-kick snuck home to give the Dutch side the lead on the stroke of half-time and Brendan Rodgers’ men unravelled after the interval as both Gustaf Lagerbielke and Odin Thiago Holm saw red.

Julian Alvarez came to the rescue for holders Manchester City, who survived a major scare before seeing off Red Star Belgrade 3-1 at the Etihad Stadium.

Osman Bukari fired the visitors in front against the run of play just before half-time but it took Alvarez 72 seconds of the second half to slide his side back in front.

Alvarez had a say in City’s second as his free-kick was flapped into his own net by Red Star keeper Omri Glazer, and Pep Guardiola’s men wrapped up a deserved victory when Rodri produced a typically composed finish 17 minutes from time.

Also in Group G, substitute Benjamin Sesko scored in injury time to seal a 3-1 win for RB Leipzig at Young Boys.

Joao Felix shone with two goals and an assist as Barcelona proved far too strong for Royal Antwerp, cantering to a 5-0 home victory in Group H.

The Portugal international fired an 11th-minute opener before Robert Lewandowski added his side’s second on 19 minutes for Xavi’s in-form side.

The visitors, returning to the top level of European football for the first time in 65 years, fell further behind after 22 minutes when Jelle Bataille’s unfortunate deflection flew in off the post.

Barca were in cruise control with teenager Gavi adding his side’s fourth goal nine minutes into the second half before the outstanding Felix deservedly completed the rout with his second just past the hour mark.

Two goals from Galeno helped Porto begin their Group H campaign with a 3-1 win over Shakhtar Donetsk in Hamburg.

Kylian Mbappe opened the scoring from the penalty spot as Paris St Germain kicked off their Group F campaign with a 2-0 win over Borussia Dortmund.

The hosts had to wait until the 49th minute for their opener but made sure of the points in the 56th minute when Achraf Hakimi doubled their advantage with a quality finish.

Rafael Leao missed a golden chance to kick AC Milan’s Group F campaign off with a win against Newcastle at the San Siro.

The Portugal international had only keeper Nick Pope to beat after a surging 34th-minute run but attempted an audacious flick and only succeeded in tripping himself.

Pope made a series of fine first-half saves to earn a point for the Magpies in their first top-level European match for 20 years, but the frustration was clear among the fans of the seven-time winners.

Kylian Mbappe grabbed yet another Champions League goal as Paris St Germain saw off a stubborn Borussia Dortmund 2-0 in their Group F opener.

The France forward took his tally to 41 goals in just 62 appearances among Europe’s elite with a controversial penalty early in the second half.

Achraf Hakimi added the second as PSG bounced back from Friday’s surprise domestic defeat at home to Nice.

The French champions now sit top of their group after AC Milan drew 0-0 with Newcastle in the earlier match.

The hosts created their first chance after only three minutes when Mbappe won a free-kick on the left wing.

Ousmane Dembele’s cross fell to Lucas Hernandez inside the six-yard box but he could only prod the loose ball wide.

But Dortmund started brightly too with Mats Hummels, who scored twice in a 4-2 win at Freiburg at the weekend, headed an early corner over before Donyell Malen’s shot was saved by Gianluigi Donnarumma.

They had a let-off after 20 minutes when Vitinha found a yard of space in the area and sent his shot crashing back off the inside of a post.

Warren Zaire-Emery was following up but was unable to adjust his feet in time to tap into an empty net.

Mbappe sent a drive wide and Dembele hit the side-netting towards the end of a frustrating first half for the hosts, while Dortmund survived a VAR check for a soft handball shot against Niklas Sule.

But the visitors had no such luck 70 seconds into the second half when Sule was penalised for handling as he dived in to block Mbappe’s shot.

The effort looked destined more for the corner flag than the goal but, despite another VAR review, referee Jesus Gil Manzano’s decision stood and Mbappe stepped up to confidently to tuck away the spot-kick.

Just before the hour PSG wrapped up the victory when Vitinha played in Hakimi, who showed a neat turn of foot to beat his marker before tucking the ball away.

Jamie Bynoe-Gittens hit the woodwork for Dortmund but the visitors never really looked capable of threatening a comeback.

Mbappe should have had a second in stoppage time after a lightning break but his chip flew wide.

Celtic had Gustaf Lagerbielke and Odin Thiago Holm sent off within five minutes of each other as they opened their Champions League campaign with a 2-0 defeat by Feyenoord in Rotterdam.

Calvin Stengs gave Feyenoord the lead in first-half stoppage-time when his 30-yard free-kick evaded a poor attempt at a defensive wall.

Joe Hart saved a penalty after Lagerbielke received a second yellow card and substitute Holm soon got a straight red card in the 68th minute.

Alireza Jahanbakhsh got the home side’s second goal.

Centre-back Lagerbielke was one of two summer signings in the Celtic starting line-up with Nat Phillips ruled out by an ankle injury. The other, winger Luis Palma, made his first start for the club.

There was a lively atmosphere inside De Kuip for the first meeting between the teams since Feyenoord’s 1970 European Cup final triumph and the first Champions League game in the stadium for six seasons.

Celtic took the edge off the atmosphere with a positive start and Reo Hatate  got the first shot on target after the Hoops won the ball high up the park, but his effort lacked power.

Celtic continued to look comfortable and could have made more of their possession had Hatate and Daizen Maeda been sharper on the ball at times.

The hosts rarely threatened to get in behind in the opening half hour and on the one occasion they did Alistair Johnston came across to cover.

Hatate’s pass got Matt O’Riley in behind but his ball towards Kyogo Furuhashi was cut out and Hart made his first save in the 34th minute when he pushed over Yankubah Minteh’s long-range strike.

Maeda broke away and saw a dangerous effort pushed wide despite being fouled in the act of shooting.

The Japan international was soon culpable for a counter-attack the other way after stopping in anticipation of a throw-in as Johnston kept the ball in, but Hart saved from Quiulindschy Hartman.

Celtic looked set to go into the dressing room deservedly level before O’Riley gave away a free-kick. Celtic’s wall failed to provide much protection especially as Furuhashi inadvertently got out of the way of the ball as he jumped. Stengs’ shot curled away from Hart with the goalkeeper unable to keep it out despite getting his hands on it.

Palma cut inside and saw his shot beaten away after the interval before Holm came on along with Yang Hyun-jun in the 58th minute.

Celtic were soon down to 10 men though. Lagerbielke had been booked in the first half for bringing down an opponent after his own poor control, and the Swede caught Igor Paixao in the throat with his arm as he tried to jockey the forward in the box.

Hart saved Paixao’s penalty as he dived to his right.

Brendan Rodgers brought on midfielder Tomoki Iwata for Furuhashi to play alongside Liam Scales in central defence.

Celtic’s task got even harder when Holm lunged in for a challenge and caught Mats Wieffer high up his shin. The visitors were rightly frustrated that Bosnian referee Irfan Peljto had failed to award a clear foul against Scales seconds earlier but there was little doubt about the red card decision that followed.

Stengs set up Lutsharel Geertruida to score from the resulting free-kick but the goal was ruled out for offside following a VAR check.

The extra men counted in the 76th minute though when Jahanbakhsh fired high into the net from 12 yards and the closing stages were about damage limitation for Celtic.

Joao Felix continued his dream start for Barcelona with two goals and an assist as his side swept past Royal Antwerp 5-0 in their first game in Champions League Group H.

The Portugal international, who scored on his debut in another 5-0 win over Real Betis at the weekend, was in superb form against the Belgians who were returning to top-level European competition for the first time in 65 years.

Barca boss Xavi showed no mercy to Antwerp as he brought Ilkay Gundogan and Raphinha into his starting line-up and watched his side predictably dominate the opening exchanges at the Nou Camp.

It took just 11 minutes for Felix to make the breakthrough when he cut in from the left and flashed the opener past visiting goalkeeper Jean Butez.

Felix turned provider in the 19th minute when he floated in a superb cross and veteran striker Robert Lewandowski pounced at the far post to steer home Barcelona’s second.

It continued a brilliant start for Felix, who figured for Chelsea last season but was deemed surplus to requirements and instead found himself loaned out from Atletico Madrid to the Nou Camp.

Antwerp’s nightmare reintroduction to the top level continued as the hosts made it 3-0 four minutes later, Raphinha’s cross clipping Jelle Bataille and flying beyond Butez and in off the far post.

Barca were in cruise control but should have extended their advantage before half-time as first Raphinha saw an effort stopped at point-blank range by Butez, then Alejandro Balde selfishly screwed a shot wide with team-mates lurking.

But it was all academic as the home side continued the one-way traffic after the break, making it 4-0 after 54 minutes when 19-year-old Gavi fired home after Lewandowski’s work had prompted another Barcelona attack.

The irrepressible Felix grabbed his second of the night in the 66th minute when he headed home from Raphina’s cross in what proved to be the last goal of a painfully one-sided contest.

Xavi introduced 16-year-old Lamine Yamal towards the end of the match, making the Spain international the youngest player to feature for Barcelona in the Champions League.

It also made Yamal the second youngest player to play in the tournament’s history, beaten only by Borussia Dortmund’s Youssoufa Moukoko.

Julian Alvarez shone as Manchester City came from behind to begin their Champions League defence with a comfortable 3-1 win over Red Star Belgrade.

The treble winners were stunned when the Serbian champions claimed a shock lead against the run of play through Osman Bukari just before half-time in Tuesday’s Group G clash at the Etihad Stadium.

Alvarez levelled quickly after the break and was then responsible for City taking the lead as his free-kick was punched into goal by the otherwise excellent Red Star goalkeeper Omri Glazer.

Rodri, matchwinner against Inter Milan in last season’s final, then wrapped up a thoroughly deserved victory with a typically composed finish 17 minutes from time.

Prior to taking the lead, City had completely dominated the game, with Glazer producing a series of fine saves to thwart the hosts and Erling Haaland hitting the crossbar.

The hosts finally started to take their chances in the second period but could have scored plenty more with Kyle Walker having an effort disallowed, Haaland again hitting the woodwork and Alvarez finding the side-netting.

Red Star boast plenty of European pedigree as winners of the competition in 1991 but, facing the continent’s present pre-eminent force, they were completely outplayed.

City had their first chance after nine minutes when Phil Foden had an effort deflected over and Rodri then jinked into the area before testing Glazer.

It was the start of a busy half for the Israeli keeper, who also denied Alvarez twice and kept out a point-blank header from Foden.

He could do little about City’s best chance of the opening period as Haaland met a floated Foden cross with a firm header but the bar came to his aid.

Haaland had another good chance to put City ahead but turned over from in front of goal.

City were made to rue their wasted chances as Red Star, who had looked to counter-attack when possible, grabbed a shock lead on the stroke of half-time.

The hosts were punished for playing a high line as Bukari was played through by Mirko Ivanic and slotted coolly past Ederson.

It initially looked like an offside flag might spare City but the goal was awarded following a VAR review.

City, who brought on Jeremy Doku for Bernardo Silva in the closing moments of the first half, quickly regrouped and equalised two minutes after the interval.

Alvarez finished superbly after being played in by Haaland, cleverly dinking over Glazer.

Walker thought he had put City ahead moments later only to be ruled offside.

City claimed the lead just before the hour as Alvarez curled a free-kick from the left into the box. Glazer came out to punch but failed to make clean contact and the ball flew in after skimming the back his hand.

Haaland went close again when he headed against a post before Alvarez lashed just wide.

City finally gave the scoreline a more realistic look when Rodri claimed their third.

The Spaniard turned Vladimir Lucic outside the area after good work by Foden and strode forward to pass the ball into the far bottom corner.
