Borussia Dortmund boss Marco Rose has revealed that a hip flexor injury will rule out talisman Erling Haaland for the next few weeks.

The striker only returned to action in last weekend's win over Mainz after a muscular problem saw him miss three games for Rose's side.

However, the 21-year-old, who has scored 13 goals in 10 appearances across all competitions this season, is now set for another spell on the sidelines. 

Addressing reporters ahead of Dortmund's trip to Arminia Bielefeld on Saturday, Rose said: "Erling Haaland won't play and will be absent for a few weeks with a hip flexor injury.

"Haaland has, of course, been down. He was happy to be back and still felt really good after the Mainz game."

Rose confirmed that Thomas Meunier and Nico Schulz will also be absent this weekend through injury.

Haaland provided fans with an update on Friday. Posting to his 1.3 million followers on Twitter, he said: "Time to focus on my recovery, I'll be back stronger."

Dortmund are second in the Bundesliga with 18 points from their opening eight games, just one point behind leaders and reigning champions Bayern Munich.

Erling Haaland is the name on everyone's lips as Europe's elite try to get their hands on the Borussia Dortmund and Norway sensation.

Haaland is already on the cusp of half a century of Bundesliga goals, having scored 49 in 49 league appearances since swapping Salzburg for Dortmund in January 2020.

It is a remarkable return – the 21-year-old has 70 goals in 69 games for the German club overall, only Bayern Munich's Robert Lewandowski (89 goals in 74 games) has a better return among players from Europe's top-five leagues.

Haaland has always been a goalscorer.

Born in Leeds in 2000, where his father Alf-Inge played for Leeds United in the Premier League at the time, Erling relocated to Bryne by the age of three – the hometown of his parents in Norway.

It is there where Erling Haaland took his first steps in football.

Alf Ingve Berntsen spent more than eight years coaching Haaland, including several matches for Byrne's first team in 2016 following the sudden departure of Gaute Larsen.

"He was the best from the first day. Scoring a lot, smiling a lot, training a lot," Berntsen told Stats Perform as he recalled Haaland's time at Byrne, where the pair worked together between the ages of eight to 16.

Haaland was part of a group of 40 talented youngsters coached by Berntsen at Bryne.

But Haaland – even playing with older kids – always stood out in a city with a population of just over 12,200 people on the southern shores of the lake Froylandsvatnet.

"A player of that level, you can spot the class from the first day… the first day you spot something special like Erling, one way or another. You can see it from the beginning," Berntsen said.

"In Norway we have a few big clubs who have academies and select best ones from a region. But most of the clubs, they have a big grassroots path. Our club is like that – part of is like a top club but a big part is grassroots. Often we try to hold them together.

"Erling was one of 40 players who trained together, in fact until they were 15. That was the first year we separated them. Erling was one year younger than the others because he was too good for his age group. He was 14. Twenty of them wanted to train four times a week and 20 wanted to train twice a week. Even then we kept them together. In that group, Erling was quite a normal guy. Funny and a desire to train and win. He was the best from the first day. Scoring a lot, smiling a lot, training a lot. He was quite similar to how he is today."

"He was quite average size but because he trained with older boys, he lacked a bit in his height. He wasn't small in size but he was skinny, very skinny," Berntsen said. "He had his growth spurt when he was 14-15. Until then, he was normal height. From 14 he started to grow very quick. He kept growing until we went to Molde. When you stop growing, it's time to develop your muscles. It's not always wise to do much building your muscles when you're growing. We knew this would happen because his family, his older brother, he is fast and strong, we knew when he was 11-12 that we had to wait some years, this was something special in the making."

After a brief period with Byrne's senior team, Haaland was lured to Molde in 2017 and after 20 goals in 50 appearances overall, the Norwegian was eventually lured to Salzburg two years later.

Haaland dazzled with Austrian giants Salzburg, scoring an absurd 29 goals in only 27 games across all competitions – he joined Alessandro del Piero, Sergei Rebrov, Neymar, Cristiano Ronaldo and Lewandowski as the only players to score in the first five matches of a Champions League group stage, while becoming the first teenager to achieve the feat.

He also scored nine times for Norway's Under-20 team in a 12-0 rout of Honduras at the 2019 U20 World Cup. Haaland did not see out a season at Salzburg, prised to Dortmund in January last year and he has not looked back.

In this season's Bundesliga, Haaland surpassed his expected goal (xG)-value by 2.9 (nine goals, 6.1 xG) – only Bayer Leverkusen sensation Florian Wirtz eclipsed his value (3.0), per Opta.

Since Haaland joined Dortmund, he exceeded his xG-value (38.7) in the Bundesliga by 10.3. It is the highest value of a player in Europe's top-five leagues in this time.

"He is very similar to now to when he was 11-12. He scores a lot. In that group, if there were 40 players, many of them were of good quality. Ten of the players with Erling, nine other players played in the region team. Four of them later came into the Under-18 national team. Erling had to conquer each training session, to win. He didn't have it always easy," Berntsen said.

"The personality and quality you see is quite similar. When he played with two defenders, they played for Norway U18 - they are strong and powerful. If he had to score in the training session, he had to be smart in his movement. Quite early he developed the smartness, the tactical ability. The whole of the group trained much outside the main session - in the indoor hall, hour after hour having fun. He gained very good technical skills.

"His mental skills were strong early. He was always more willing to win. The technical and mental part were very good. He lacked a bit physically. We knew to wait some years and this might explode. The personality, desire and passion is just what it was earlier."

"When he moved up to us, because of the quality of the group, he didn't have to be too high on his self because it wasn't too easy," Berntsen continued on Haaland's attitude and character. "We didn't know if we were going to lose or win in training.

"This is a small place where 12,000 live. everyone knows each other. He had to develop with no media around. It was a good place for him. No big attention. He had to train and develop without any disturbance because if you are in a big city and club, you can have a lot of attention and it isn't so easy. But here he could train with his friends and develop steady. His father had played in the Premier League, so in this area everyone knew who he was."

Since Haaland's arrival in Dortmund, he has scored 13 Bundesliga goals after carries – in Europe's top-five leagues, it is only bettered by six-time Ballon d'Or winner Lionel Messi (15).

In the 2021-22 league campaign, Haaland is one of four players who has been involved on 10 open-play sequences which ended in a goal – together with Hoffenheim's Andrej Kramaric, Bayern veteran Thomas Muller and Wirtz.

While Berntsen predicted a great career, not even he could have envisaged the speed of Haaland's rise to the top amid links with the likes of Real Madrid, Manchester United, Barcelona, Bayern, Manchester City, Chelsea, Liverpool, Paris Saint-Germain and Juventus.

"I didn't see that at this age that he would become top scorer in the Champions League like he did or score in each match at this level. But we're not surprised that he is doing well," Berntsen said.

"When he got the first possibility to play in the regions team, he was picked then the national team, you can play from 15, and he was picked and scored. He always kept scoring at a new level. At a time when he lacked a bit physically. We knew he would become strong and fast. Of course we didn't see that level at that early age. But many of us, we were quite sure he was going to have a good international career, from 12 years old."

He added: "When you're 21, the body isn't fully grown yet. It can develop in all aspects of the game but it's not too easy now because the level he is on is high already. But when you're trying on a daily basis, you train to get better. If you do that, you'll have a small percentage of growth.

"He is one of the new rising stars that can do a lot of different - high pressure, low pressure, he can run, smart in the box, quite good in offence and defence. The next generation of players will have that variety - not just one type on top. He can be a front man or in counter-attacks. That might be common in the future. You have quite good variants in quality. There are still things for him to develop."

Prior to matchday-three fixtures in the Champions League, only Lewandowski had scored more goals and a higher xG-value across all competitions in the top-five leagues this season than Haaland.

Dating back to his switch from Salzburg in 2020, Haaland eclipsed his xG-value in his Champions league performances by 4.1 – the highest value of a player in the Champions League in this time prior to the club's 4-0 rout at the hands of Ajax.

While only Lewandowski has been involved in more Champions League open-play sequences that ended in a goal than Haaland since the latter's transfer to Germany (before Dortmund and Bayern's fixtures this week).

When asked where Haaland – who has a return of 12 goals in 15 international appearances for Norway – would be best suited if he were to leave Dortmund, Berntsen replied: "There's not so many possibilities now. There may be a few clubs who can afford him. It's not for everyone.

"Erling and his family, they've done a brilliant job to select the next level. If he stays in Dortmund, if he was to end his career there, still he had a brilliant career because he's a funny guy from a little town. 

"Erling is down to earth. If you have a job and have big defenders knocking you down, you have to make a statement and prove yourself. He is a loveable guy and we are proud of him. Humble. If you asked me a year ago, I'd say maybe Spain or England but Spain or France now."

Bayern Munich head coach Julian Nagelsmann has tested positive for COVID-19.

Nagelsmann was absent due to 'flu-like symptoms' as Bayern beat Benfica 4-0 in Portugal on Wednesday, maintaining their flawless Champions League group-stage record so far this season, with assistant manager Dino Toppmoller standing in.

The Bavarian giants have won each of their first three games in the competition, scoring 12 times and not conceding a single goal to sit five points clear at the top of Group E.

The club confirmed on Thursday morning that the 34-year-old, despite being fully vaccinated, had tested positive for the virus and will return to Munich separately instead of with the rest of the squad before isolating at his home.

As a result, Nagelsmann will miss Bayern's next league game at home against Hoffenheim on October 23, with Toppmoller set to continue filling in.

Bayern are one point ahead of Borussia Dortmund at the top of the Bundesliga, winning six and losing just one of their first eight games as they seek a 10th consecutive league title.

Ole Gunnar Solskjaer was "sure" Manchester United would beat Atalanta after match-winner Cristiano Ronaldo completed a dramatic Champions League comeback on Wednesday.

Ronaldo was the hero again at Old Trafford, where United overturned a two-goal deficit to stun visiting Atalanta 3-2 on matchday three in Group F.

United trailed 2-0 before the half-hour mark in Manchester after Mario Pasalic and Merih Demiral shocked the Theatre of Dreams.

Reeling after a 4-2 Premier League defeat at Leicester City last time out and just two wins in their previous seven games, the Red Devils were given a glimmer of hope when Marcus Rashford pulled a goal back eight minutes into the second half – the club's 300th strike in all competitions under Solskjaer.

United captain Harry Maguire equalised with 15 minutes remaining before superstar Ronaldo stepped up to complete the fightback nine minutes from time.

On what he said at half-time, Solskjaer told BT Sport: "I said make sure we get the next goal, because then we win the game.

"As long as we don’t concede I was pretty sure we would win the game. It was just about taking chances."

"I thought we played well first half too. Two chances, two goals. It had to stop if we are to survive," Solskjaer said after United rallied from two or more goals down for the third time – no side has done so more often in the Champions League.

"We have a habit of doing this at this club. I thought we played well and they scored a goal out of nothing and then another set-piece. But they never stopped believing and kept going."

"The fans are a big, big part of this club," Solskjaer added. "The singing section here today kept the players going in their belief. That is what you do at Manchester United on a Champions League night."

Solskjaer defended Ronaldo following some criticism that he does not work hard or defend enough for the Premier League giants.

Ronaldo has now scored in three consecutive Champions League games for United for the second time – the 36-year-old five-time Ballon d'Or winner previously doing so in November 2007 en route to lifting the trophy with the Red Devils.

“If anyone wants to criticise him for work rate or attitude, just look at the way he runs around in this game," he said.

Solskjaer has found himself under growing pressure amid United's poor form and performances and when it was put to him whether the squad had played for him midweek, the Norwegian responded: "Don't disrespect the players.

"They played for Man United and they are the luckiest men in the world because they're the ones who get to play for Man United and millions of boys and girls would love to do that."

Gerard Pique scored the only goal as Barcelona beat Dynamo Kiev 1-0 at Camp Nou to get off the mark with their first victory in this season's Champions League.

Barca had lost their opening two group games for the first time ever, going down 3-0 to both Bayern Munich and Benfica, but they were good value for the three points.

Pique volleyed in a first-half opener to end a run of 287 minutes without a goal in the competition for the Catalans and they looked comfortable without adding to their scoring.

The win moves Ronald Koeman's men above Kiev into third place in Group E, a point behind Benfica and three off Bayern Munich, with those two sides meeting later on Wednesday.

Barca had recorded fewer shots on target (one) than any side in the competition heading into gameweek three and that lack of cutting edge was again on show as Sergino Dest failed to test Georgi Bushchan with a close-range header early on.

Luuk de Jong was also off target with a headed attempt from six yards, though the striker did at least manage to force Bushchan into a first save three minutes later with a curled shot from the edge of the box.

The hosts' breakthrough duly arrived through Pique with 36 minutes played, the centre-back being left in space to guide in Jordi Alba's latest exquisite cross with a first-time finish.

Ansu Fati, brought on for the ineffective De Jong at half-time, wasted a good chance to score Barca's second when getting his angles all wrong and sending an overhead kick wide of the target.

Barca could not fashion any more opportunities, but the Ukrainian champions failed to ask any questions of their opponents, not registering a single shot on target as Pique's goal proved the difference.

Former Argentina head coach Alfio Basile has criticised "messy" Paris Saint-Germain's use of Lionel Messi and says the Ligue 1 side have "a weak defence".

Barcelona's financial difficulties forced Messi to find a new club, eventually joining PSG on a free transfer in August. 

The six-time Ballon d'Or winner got off to a slow start in France, scoring just once in his first four appearances across all competitions and missing several games due to injury.

Basile, who had two spells in charge of Argentina (1991-1994 and 2006-2008), winning two Copa Americas and a FIFA Confederations Cup in a successful first stint, hit out at how PSG boss Mauricio Pochettino was deploying Messi.

"The problem that Messi has is that at PSG, he is playing on the right and with Argentina, he plays everywhere, he makes everyone play." Basile said to SuperMitre.

The former Barca superstar, who won the Copa America with Argentina in July and was named the player of the tournament after registering the most goals and assists, enjoyed a breakthrough evening for his new club as PSG beat RB Leipzig 3-2 on Tuesday, scoring twice.

Basile was scathing in his assessment of the Ligue 1 giants as a team, however, pointing out their defensive organisation as a particular problem.

"PSG have a very weak defence and are very messy," Basile added.

PSG have the seventh-worst expected goals against total in the Champions League so far this season (5.39) but have only conceded three goals, keeping one clean sheet.

Bayern Munich defender Dayot Upamecano said Robert Lewandowski and Real Madrid star Karim Benzema are both worthy of this year's Ballon d'Or.

Lewandowski and Benzema are among the nominees for football's most prestigious individual award – the 30-man shortlist will be whittled down to just three players.

Upamecano is team-mates with Lewandowski at Bundesliga champions Bayern, while he also plays alongside Benzema for World Cup and Nations League holders France.

Asked about Lewandowski and Benzema ahead of Bayern's Champions League fixture with Benfica on Wednesday, Upamecano replied: "Very good question!

"Lewandowski or Benzema, both of them deserve it [Ballon d'Or]. They are the two best strikers in the world. They prove it year after year.

"If Lewandowski wins, I would be very happy for him because he is my team-mate at Bayern. If Benzema wins, I also would be very happy for him."

Prior to Madrid's 5-0 rout of Shakhtar Donetsk on Tuesday, Benzema had been involved in more shot-ending sequences of play (76) than any other player in the Champions League.

In this same period, Lionel Messi (12) was the only player who had recorded more multi-shot involvements than Benzema (10), which captures all instances of sequences where a player is both involved in the build-up and takes the shot.

Meanwhile, Lewandowski has scored five goals in six Champions League appearances against Portuguese opponents, including three against Benfica – no player has ever scored more times against sides from Portugal in the competition.

Bayern are on a record unbeaten run of 19 matches away from home in Champions League (W15 D4), netting 54 goals during this streak since losing 3-0 at Paris Saint-Germain in September 2017. Over a third of their goals in this unbeaten run have been scored by their Lewandowski (19 – 35 per cent).

German giants Bayern's eight unbeaten matches against Benfica in the European Cup/Champions League (W5 D3) is the joint-most by a team against an opponent since the tournament began in 1955 – Bayern versus Spartak Moscow (W5 D3) and Barcelona versus Lyon (W5 D3) have also faced eight times without ever losing.

Since the start of last season, Bayern have averaged more goals (3.2) and have a higher expected goals tally (2.6) per game than any other team in the Champions League. Among teams involved in both the 2020-21 and 2021-22 tournaments, they also have the highest shot conversion rate in this period (18.3 per cent).

Julian Nagelsmann fired a warning to defences across Europe by claiming Robert Lewandowski has a long time left at the top level – insisting the Ballon d'Or should come his way this year.

Although Bayern Munich striker Lewandowski turned 33 in August, there is no indication age is catching up with the Poland international.

His record haul of 41 Bundesliga goals last season came at a rate of one every 60.07 minutes.

That was the fastest rate of scoring across a campaign, in terms of minutes per goal, for any player with 10 or more goals in a Bundesliga season since the league was founded in 1963.

After missing out on Ballon d'Or recognition last year, when the award was cancelled due to the pandemic's impact on the global game, there is little doubt Lewandowski is a serious contender this time.

Bayern did not match up to their 2019-20 treble-winning feats, but they carried off a ninth consecutive Bundesliga title and Lewandowski was their spearhead.

"He deserves the Ballon d'Or – and in my opinion he has to win the award, because he has played more consistently than anyone else over the past three years," Bayern head coach Nagelsmann said.

Speaking to Munich newspaper Abendzeitung, Nagelsmann predicted Lewandowski would continue to thrive at the highest level into his late thirties.

"If Robert Lewandowski's body stays like this, it is far from over," said Nagelsmann.

"He is extremely dynamic, has no injuries, he can train a lot: I definitely trust him to play at the top, top level for a few more years – also because he aligns everything in his life accordingly, to be in the best physical condition."

In Bayern's triumphant 2019-20 Champions League campaign, Lewandowski netted 15 times, scoring on average once every 59.13 minutes. This term, he has four goals already in that competition from just 169 minutes on the pitch.

Lewandowski has said it "would mean a lot" to scoop the individual honour, and after being shortlisted his chief rival appears to be six-time winner Lionel Messi, who helped Argentina to Copa America glory.

Nagelsmann, meanwhile, is sitting tight when it comes to the future of Bayern defender Niklas Sule, whose contract expires at the end of this season.

Sule has been linked with Chelsea and Newcastle United, and Nagelsmann is taking a wait-and-see approach to what comes next for the Germany international.

"It depends on his development and also on the market situation whether he wants to extend the contract or not," Nagelsmann said. "Then we'll see if it works for both sides.

"Niki still has to develop a little with his potential and then make the most of it as a very good central defender."

Diego Simeone hopes Antoine Griezmann will soon respond to his critics after Atletico Madrid were held to a goalless draw with Porto in the Champions League.

Atletico failed to win their opening game for the third consecutive season and are now winless in four home matches in Europe's premier club competition, their joint-longest streak without a victory.

Griezmann was introduced as a second-half substitute amid boos in search of a winner but failed to provide attacking impetus as he did not manage to record a single touch in Porto's box.

Following an underwhelming second debut against Espanyol following his return from Barcelona on loan, the pressure is now on the France forward, who already had to win supporters over on his comeback after his move to Camp Nou.

But Simeone is backing Griezmann, whose 21 goals for Atletico in the Champions League are nine more than any of their previous players in history, to prove his doubters wrong.

"Let's hope that he [Griezmann] gets better, that he can respond to all the people who criticise him at this time," Atletico head coach Simeone said to Movistar.

"He has a challenge ahead of him as a result of what happened in the past.

"They [the media] are making a movie and a morbid situation that clearly generates for us only the importance of having recovered a magnificent footballer whom we hope to recover."

Wednesday's result means LaLiga champions Atletico have now just won two of their last 10 European fixtures, but Simeone insisted he will drive his side towards improvements.

"The team has improvement ahead, we have work," he continued.

"We will aim for that, to find what makes the team better so that it maintains continuity in the game for as many minutes as possible.

"The system is a way of looking for variants so that the team can find solutions to the match. We have players who can play in different positions.

"We always did, last year we played various formations. We play with all systems."

Jurgen Klopp felt Liverpool "got carried away by our own football" as they let a lead slip against Milan before recovering to win 3-2 in their Champions League opener.

An own goal from Fikayo Tomori gave Liverpool the lead in the ninth minute at Anfield before Mohamed Salah saw a penalty saved by Mike Maignan.

Two goals in the space of 110 seconds turned the game on its head, however, with Ante Rebic and Brahim Diaz putting Milan, playing their first Champions League game since 2014, 2-1 up at half-time.

However, Salah atoned for his penalty miss three minutes after the restart and a superb long-range effort from Jordan Henderson, his first goal in the competition for 2,485 days, settled matters for Liverpool to send them top of Group B.

Klopp made four changes from the Premier League win over Leeds United, with Joe Gomez starting in defence and Divock Origi up front.

And he felt the alterations had an impact on Liverpool losing control of the match for a brief period.

He told BT Sport: "We started incredibly well. We played a super, super game. An intense game but football-wise as well. We played in all the spaces we had to play and didn't give them anything until... I'm not sure exactly. We got punished for it in the last few minutes of the first half but it started earlier.

"We got carried away by our own football. We didn't keep it simple anymore, offensively and defensively we were not organised anymore.

"When we are organised, Fabinho is incredible and he can pick up all the challenges we need him for. When the spaces are too big, even he cannot solve it anymore.

"They played in between and scored two goals. But it did not feel like we cannot come back. It was clear that we had to immediately get back to how we started and then we scored wonderful goals, to be honest. Both were incredible.

"It is deserved but we had 10 minutes where Milan nearly changed the whole tie.

"It is the football I want to see in most moments. We are experienced in the competition, or should be. It was a little bit the changes as well that we just weren't compact anymore.

"Now we won I can say that the changes was the right thing to do because playing every three days is just not possible with the same guys. The guys who came on did incredibly well.

"That is our pick from pot four. AC Milan in a really good moment. It is a tough group. That is why it is important we won this game. It does not decide anything but it gave us a winning start."

Barcelona president Joan Laporta has called for patience and trust from the fanbase as he attempts to "solve" the Catalan giants' on and off the field problems.

Years of financial mismanagement caught up with Barca last month as they lost Lionel Messi to Paris Saint-Germain on a free transfer.

Antoine Griezmann was also sent back to title rivals Atletico Madrid on an initial loan amid a flurry of late activity in an attempt to help balance the books.

Barca's solid, if not spectacular. start to the LaLiga campaign, in which they have picked up seven points from a possible nine, helped lift the mood around Camp Nou somewhat.

But a crushing 3-0 loss to Bayern Munich on Tuesday – the first time Barca have lost their opening Champions League game in 23 seasons – has changed all that.

Sergi Roberto was booed by a section of his own supporters when being substituted off during the game, which captain Gerard Pique admitted left him feeling "hurt".

With supporter unrest growing during a tough period for the LaLiga heavyweights, Laporta issued a video statement on his social media channels on Wednesday.

"Hello Cules. I am as disappointed and upset as all of you are," he said. "I need to tell you what is happening. This is one of the situations that we expected. 

"I ask you all for your patience, and that you continue supporting our team. I also ask you to trust us, the people who are managing the club. 

"We need your trust and time. Do not doubt that we will solve the situation."

Bayern's prolific striker Robert Lewandowski helped himself to a double after Thomas Muller had opened the scoring in the first half of Tuesday's Group E clash.

Barca have lost three successive home games in European competition for the first time in their history, having also lost to Juventus and Paris Saint-Germain at Camp Nou last season.

In their first European game since Messi's exit, the Catalans failed to register a shot on target in a Champions League match for the first time since Opta started recording such data in 2003-04.

Barcelona's injury problems have deepened as midfielder Pedri and left-back Jordi Alba have been ruled out with muscular injuries sustained in the 3-0 defeat to Bayern Munich.

Alba was taken off in the 74th minute of Tuesday's Champions League contest with a hamstring issue, while Pedri played a full part on his return to action following a three-week rest.

Barca announced on their official website on Wednesday that Pedri is suffering with a thigh problem and has joined Alba in the treatment room ahead of Monday's LaLiga clash with Granada.

No timeline has been given for both players' return to action.

"The first team player Pedri has a quadriceps muscle injury in his left thigh," Barca revealed. "The player is unavailable for selection and his recovery will dictate his return.

"Tests carried out on Wednesday morning on the first team player Jordi Alba show that he has a hamstring injury in his right thigh. 

"The player is unavailable for selection and his recovery will dictate his return."

Barca's injury issues are piling up ahead of a busy spell of five games in a fortnight, including a huge clash with LaLiga champions Atletico Madrid early next month.

Martin Braithwaite is expected to miss the rest of 2021 after undergoing knee surgery, while fellow attackers Sergio Aguero, Ousmane Dembele and Ansu Fati are also out of action.

According to Spanish outlet Marca, Barca boss Ronald Koeman feels the club's medical department are partly to blame for the growing list of absentees.

The loss of Alba will leave a big void to be filled in the troublesome area of left-back, with academy product Alejandro Balde coming on for his senior debut in the heavy defeat to Bayern.

Pedri has also been a regular under Koeman over the past 13 months, making 55 appearances in all competitions since the start of last season – only Youssef En-Nesyri (57) and Manu Trigueros (59) have been used more often among LaLiga clubs.

Paulo Dybala expressed his desire to resolve his contract renewal with Juventus after helping the Serie A giants defeat Malmo in their Champions League opener.

Dybala scored Juve's second from the penalty spot in Tuesday's 3-0 victory as they coasted to a sixth consecutive group-stage away win and maintained their perfect record against Swedish opposition in Europe.

However, with less than a year left on Dybala's contract, there is the possibility that the 27-year-old could depart on a free transfer at the end of the season.

Juve vice-president Pavel Nedved sees the former Palermo star as a central piece to his project and reassured that his side are confident of reaching an agreement – a sentiment Dybala echoed on Tuesday.

"My renewal? I always try to give my best," Dybala provided a post-match update to Sport Mediaset.

"The parties are talking, there are great expectations from everyone. We hope for a good ending.

"I'm happy to score. It helps me psychologically, it makes me play calmly, with serenity, to help the team. Today we won and I'm very happy.

"We were returning from bad performances, the results did not support us, but we knew that this is another competition and what to do. We did it, playing with serenity, as a great team. Now we must continue on this."

Bayern Munich head coach Julian Nagelsmann admits Tuesday's Champions League opponent Barcelona will miss Lionel Messi's "extravagance" but believes they are not much weaker without him.

Messi left Barcelona in the off-season to join Paris Saint-Germain after a glittering career at Camp Nou.

The Catalans have started life domestically without Messi with seven points from three games in LaLiga, while they will commence their Champions League campaign on Tuesday against Nagelsmann's Bayern in Barcelona.

"Barcelona definitely don't have the extravagance of a Messi any more. But they also have other players who can play a very important role if you take Frenkie de Jong and Pedri for example," Nagelsmann said at the pre-game news conference.

"We are ready for anything. I don't believe they are much weaker. The future will show if they are any better. But we definitely want to take three points."

Barcelona have a variety of selection issues with injuries to Ousmane Dembele, Ansu Fati, Martin Braithwaite and Sergio Aguero, while Nagelsmann was coy on Serge Gnabry's availability.

Gnabry was substituted with a back problem in Saturday's 4-1 Bundesliga win over RB Leipzig, along with Robert Lewandowski for "precautionary" reasons with a groin complaint.

"We'll have to make a late decision on that one," Nagelsmann said about Gnabry.

"Gnabry will travel. [Corentin] Tolisso will not. [Kingsley] Coman is in the squad but not an option to start. It's looking good for Lewandowski again though."

Bayern thrashed Barcelona 8-2 in the 2020 Champions League quarter-final played as a one-off in Lisbon, adding further spice to their opening Group E fixture.

"Being the favourites or not the favourites is always more of a subject for the media," he said. "Two world-class clubs face each other."

Serge Gnabry will "probably" miss Bayern Munich's Champions League opener against Barcelona on Tuesday, according to Hasan Salihamidzic. 

A back problem forced Gnabry off in first-half stoppage time during Bayern's 4-1 victory at RB Leipzig in the Bundesliga on Saturday. 

The 26-year-old started two of Germany's three World Cup qualifiers during the international break and was introduced as a second-half substitute in the other. 

Salihamidzic was frustrated that Gnabry sustained an injury after playing in all those matches, while Borussia Dortmund captain Marco Reus left early with a knee injury but recovered in time to face Bayer Leverkusen this weekend. 

Reus withdrew from selection for Euro 2020 but had said he wanted to play "an important role" for Germany ahead of the three qualifiers. 

"I find it surprising when you leave the national team and then play again a few days later. Our players stay and play anyway," Salihamidzic told Sky. 

"It's not the first time either. When you're injured, okay, you drop out, but otherwise... Serge Gnabry stayed there. He'll probably be out against Barcelona now, but that's just the way it is. 

"If you want to be a leader, you always have to be there. Otherwise, a team won't work. What [Joshua] Kimmich does, what [Manuel] Neuer does, what [Leon] Goretzka does – that's leadership for me. The coach can rely on that." 

On Gnabry's availability to face Barcelona, he added: "It's getting really tight. He's been treated and it's already better. I was there today and saw him. We'll have to see if it's enough." 

However, Bayern could be boosted by the return to fitness of Kingsley Coman. 

Coman withdrew from France duty due to a calf injury and reportedly returned to training in Bavaria on Sunday. 

Bayern boss Julian Nagelsmann is also confident of having Robert Lewandowski available for selection following the striker's early withdrawal against Leipzig for "precautionary reasons".
