Barcelona coach Hansi Flick did not want to speculate about the time Marc-Andre ter Stegen could spend on the sidelines after the injury the goalkeeper suffered against Villarreal.

Barcelona maintained their perfect start in LaLiga by winning 5-1 on Sunday.

However, the win was marred by possibly a season-ending injury of their goalkeeper, who had to be taken off in the first half.

"It looks like a serious injury, he felt it, you could see it on the pitch," Flick told reporters.

Ter Stegen fell badly after jumping for a ball just before half-time and was visibly in pain as he was carried off the pitch on a stretcher.

All of Germany international's weight fell on his right leg.

Ter Stegen injured the same knee, on which he already underwent two surgeries over recent seasons, and another operation could prove to be the end his campaign, according to some reports in the Spanish media.

Asked whether he had already thought of a replacement, Flick said: "I don't like this question right after the game. First we have to see what happens with Marc, he's our captain.

"I'm very sad about what happened. Please understand that I don't want to answer this question. I haven't been able to speak to Ter Stegen."

Robert Lewandowski, who scored twice in the rout, dedicated the win to Ter Stegen.

"We don't know exactly what happened, he's in hospital, but of course we are very sad, and this victory is for him," Lewandowski said.

Atletico Madrid lost early ground to Barcelona in their quest for the LaLiga title as they were held to a 1-1 draw with city rivals Rayo Vallecano on Sunday. 

The visitors withstood an early spell of pressure and almost took the lead in stunning fashion when Julian Alvarez's strike from distance cannoned off the crossbar. 

But Diego Simeone's side found themselves a goal down in the 35th minute when Isi Palazon turned home Raul de Tomas' cross after good work from Jorge de Frutos.

However, parity was restored four minutes after the break when Conor Gallagher struck beyond Augusto Batalla from the edge of the area to net his second goal in as many games for his new club. 

Atletico continued to push for a winner, with Alvarez and Angel Correa going close, but Rayo Vallecano were able to hold firm for the closing exchanges. 

The result leaves Simeone's side in fourth place, six points behind league leaders Barcelona who thumped Villarreal 5-1 earlier in the day. 

Data Debrief: Gallagher embracing advanced role

Having only scored 10 goals in 90 appearances for Chelsea, Gallagher is flourishing under Simeone's stewardship in Spain. 

During the contest, only Koke and Alvarez (both 14) made more passes into the final third than Gallagher (11), with his strike coming from an expected goals (xG) total of just 0.06. 

But the England international did not neglect his defensive responsibilities. Gallagher won more tackles (four) than anyone on the pitch, while also winning three fouls.

Robert Lewandowski and Raphinha both scored twice to help Barcelona thrash Villarreal 5-1 on Sunday.

Barcelona suffered their first defeat of the season when they went down to Monaco in the Champions League in midweek, but Hansi Flick's team bounced back in style in LaLiga.

They have now won their opening six league matches under Flick to start the season.

Lewandowski found the net twice inside 35 minutes before Villarreal pulled a quick one back through Ayoze Perez.

But Pablo Torre made it 3-1 after the break and Raphinha completed the rout for Barca with two goals late in the second half.

Barcelona did, however, lose goalkeeper Marc-Andre ter Stegen just before half-time after the German goalkeeper fell and was visibly in pain as he was carried off the pitch on a stretcher.

The Blaugrana remain top of the standings as they preserved a four-point lead over defending champions Real Madrid in second. 

Data Debrief: Ten in a row for free-scoring Barca

That is now 10 LaLiga wins on the spin for Barca over the course of this season and the end of last. That is their longest such winning streak since 2017, when Lionel Messi was still running the show.

Barca have now scored 23 goals in all competitions this season, a tally bettered only by Bayern Munich (29).

The Blaugrana's five goals on Sunday came from 4.08 xG, though Villarreal did have chances of their own, accumulating 2.11 xG, so Flick will want to see his team tighten up at the back.

Diego Simeone says Atletico Madrid have no choice but to manage their players' minutes with the new Champions League format dialling up the intensity of their schedule.

Atleti have made a positive start to the season, registering three wins and two draws from their first five matches in LaLiga to match Real Madrid's pace and sit four points adrift of leaders Barcelona.

They also made a winning start to their Champions League campaign in midweek, fighting back to beat RB Leipzig 2-1 with a last-gasp winner from Jose Maria Gimenez.

With eight European league-phase games to play this term, Atleti face an incredibly busy schedule, with no free midweek slots until December, excluding international breaks.

After going to Rayo Vallecano on Sunday, Los Colchoneros visit Celta Vigo on Thursday then face Real Madrid, Benfica and Real Sociedad in the space of a week. 

"It makes us try to manage the squad in the best way but the difficulties come in the hours approaching the game, when we need to win," Simeone said ahead of Sunday's trip across the Spanish capital. 

"The word rotation is not good, it is an opportunity for those who play and you cannot always repeat the same players, because then you are on the way to significant injuries as we have seen.

"On our physical side, we have to try to manage their health in the best way. Only with health can we have a team.

"On the pitch there is little to work in the time we have left for each game, especially when it is Thursday and Sunday."

Luka Modric lauded Real Madrid's attacking ranks as the LaLiga champions fought from behind to thrash Espanyol 4-1 on Saturday.

Thibaut Courtois' blunder handed the visitors a shock lead in the 54th minute, only for Dani Carvajal to level four minutes later after Jude Bellingham's cross was spilled by Joan Garcia.

Vinicius Junior's introduction breathed life into Carlo Ancelotti's side, however, teeing up Rodrygo's first-time finish with 15 minutes remaining.

Brazil star Vinicius followed that up with a goal of his own to make it 3-1 before Kylian Mbappe sealed all three points with his third penalty in as many LaLiga games.

Madrid captain Modric still saw room for improvement but acknowledged the attacking quality Los Blancos have after moving one point behind leaders Barcelona, who visit Villarreal on Sunday.

"We played a very good game but it's true that it was difficult for us to finish plays. We created a lot of chances but we have a lot of room for improvement," Modric told Movistar Plus.

"I don't know if it was our best or not but it was a great game, from start to finish. We must continue like today. To have Vinicius, Mbappe, Bellingham and Rodrygo is awesome; they are great.

"They and the whole team are doing everything right but we still can improve; we'll keep going in the next few games until we feel we reach out true potential. This match can give us confidence."

Vinicius was left on the bench but his second-half impact saw him both score and assist in a single Madrid game as a substitute for the first time in his career across all competitions (272 games).

That set the stage for Mbappe to put the result beyond any doubt, becoming just the second Madrid player this decade to score penalties in three straight LaLiga games, after his compatriot Karim Benzema.

A fine fightback performance left Ancelotti delighted, though the Madrid head coach was still cautious, primarily due to managing Bellingham's troublesome should injury.

"We started well and reacted well after the 1-0, it was complete," Ancelotti said, as quoted by AS.

"We played better than in other games; with more rhythm and generating more opportunities. I'm happy.

"Jude has had the shoulder problem and it has resolved well. He was able to play the whole game without any problem.

"He's always played with protection. A month ago he took it off because he was fine, but he has had this problem again. I don't think it will be a problem, although it must be taken care of, obviously."

Vinicius Junior came off the bench to score one and assist another as Real Madrid battled from behind for a 4-1 fightback victory over Espanyol in LaLiga.

Madrid dominated proceedings on Saturday but fell behind in the 54th minute after a rare blunder by goalkeeper Thibaut Courtois, who inadvertently deflected a low cross from Jofre into his own net.

Carlo Ancelotti's side found an equaliser just four minutes later, however, with a close-range strike by Dani Carvajal on the follow-up from Jude Bellingham's cross.

Vinicius worked his magic soon after, lifting a brilliant cross to Rodrygo – who netted with a 75th-minute first-time effort – before scoring himself with a tidy finish from a counter-attack only three minutes later.

Kylian Mbappe finished off the win from the penalty spot after substitute Endrick was fouled inside the box in the 90th minute.

Madrid remain second on 14 points, one behind leaders Barcelona, who have a game in hand and visit fourth-placed Villarreal on Sunday. 

Data Debrief: Penalty perfection for Madrid and Mbappe

Mbappe has scored three of his four goals from 12 yards in Spain's top division, making him just the second Los Blancos player to score from the penalty spot in three consecutive LaLiga matches this decade.

Former international team-mate Karim Benzema was the other Madrid player to manage to do so, between March and April 2022 (also three), and Mbappe will be hoping to follow in his countrymen's footsteps.

Vinicius' influence should not be ignored, however, with the Brazil winger scoring and assisting in the same game as a substitute for the first time in his Madrid career across all competitions (272 appearances).

That pair ensured a dominant outing for comeback kings Madrid, who accumulated a massive 4.49 expected goals (xG) to Espanyol's minimal 0.24.

Girona slumped to a surprise 2-0 defeat at struggling Valencia on Saturday as an own goal by Juanpe and a deflected strike from Dani Gomez gave the hosts their first win of the season in LaLiga. 

The victory moved Valencia from bottom to 18th on four points, one ahead of Getafe and two ahead of Las Palmas. 

Last year's surprise package Girona, meanwhile, are 13th on seven points from their first six games of the campaign, having also lost their Champions League opener at Paris Saint-Germain in midweek.

Valencia dominated proceedings from the early stages but needed 56 minutes to break the deadlock, with Gomez's long-range strike deflecting off Juanpe and wrong-footing Girona goalkeeper Paulo Gazzaniga.

The hosts had daylight just two minutes later as Gomez slotted a finish inside the left-hand post from the edge of the box, and Michel's men were unable to respond as they suffered their third defeat of the season.

Data Debrief: Efficiency key for Valencia

Valencia only recorded one shot on target in a match low on high-quality chances, with both teams' total expected goals (xG) figures adding up to just 0.77 xG.

This is the first time since at least the 2003-04 season, when Opta records began, that they have won a match in LaLiga, and scored twice, when only managing one shot on target.

Hansi Flick insists Barcelona will use "no excuses" when his injury-hit side head to Villarreal for Sunday's LaLiga clash.

Midfielder Fermin Lopez suffered a muscular problem in his right thigh while training on Tuesday, becoming the latest addition to Barca's growing list of injured absentees.

New signing Dani Olmo is sidelined for at least a month with a hamstring injury, alongside fellow midfielders Gavi, Frenkie de Jong and Marc Bernal, and defensive pair Ronald Araujo and Andreas Christensen.

Though struggling with limited selection options due to the fitness issues plaguing the visitors' squad, Flick is adamant the LaLiga leaders can adapt to find a workaround.

"When we started the season, I said there would be no excuses," Flick said. "We're going to be able to manage the game, although we'll be careful with some players carrying a lot of load.

"Tomorrow we'll manage this, although I'm sure that those who come on will be at 100%. The medical team is helping us and we are taking special care with [Pau] Cubarsi, who has been recovering."

Barcelona have made a perfect start to the LaLiga season under the German, with five straight wins putting them top of the standings, four points ahead of defending champions Real Madrid.

The only blemish on the Blaugrana's record came in Thursday's 2-1 defeat against Monaco, with Eric Garcia dismissed just 10 minutes into the Champions League opener.

"We have a great team, and we have shown it," Flick added. "Every season it's the same, there are weeks when you lose several players, but as a coach, it's something you have to accept.

"Now we have to focus on those who are available to prepare them for the next game."

Flick will at least be able to call upon returning forward Ansu Fati, who has scored four goals in six games against Villarreal in LaLiga, his most against one opponent in the competition.

Fati, along with Raphinha, Lamine Yamal and Robert Lewandowski, will hope to cover the midfield void with their attacking prowess that has propelled Barcelona to success this term.

Indeed, Barcelona are the top-scoring team in Europe's top five leagues this season with 17 goals, a tally that they will aim to add to on Sunday.

Girona head coach Michel has tasked his players to "turn the page" following their 1-0 defeat to Paris Saint-Germain on their Champions League debut. 

Girona frustrated their Parisian hosts, restricting Luis Enrique's side to just five shots on target from the 26 they attempted.

However, Blanquivermells hearts were broken in the 90th minute after Nuno Mendes' harmless delivery slipped through the hands of Paulo Gazzaniga. 

But the Catalan club's focus now returns to league action, having started the season with seven points from their opening five fixtures. 

Michel's side travel to the Estadio de Mestalla to face bottom-placed Valencia, a team they have enjoyed relative success against in recent years. 

Girona have won four of their eight meetings with Valencia in LaLiga (L4); only against Sevilla (six) have they achieved more wins in the top-flight (four also against Rayo Vallecano, Las Palmas and Celta Vigo).

And Michel insisted that despite their late defeat in midweek, his players are ready to return to winning ways. 

“The team is back to thinking only about LaLiga,” Michel told reporters.

“In situations of maximum physical and emotional exhaustion, perhaps there are still players who are still recovering. But our squad is very prepared.

"We need to be at our best, and we need the team switched on.

"After the historic game against PSG, people who have been playing for more years can turn the page quicker.

"Now, my job is to detect which players are in a better state of mind. We have shown that we are a small team with pride.

"That's why I need the people to be on board, to give the maximum help to their teammates."

Valencia have endured a difficult start to the campaign, picking up one point from their first five games. 

This weekend's hosts have now failed to win in their last 12 games in LaLiga. Their last joint longest winless streak was from November 2015 to February 2016.

Michel also boasts an impressive record against Valencia, winning three of his six league games against them (D1 L2). 

Only against Sevilla (five) has the Girona head coach recorded more wins as a top-flight coach (three, also against Alaves, Celta Vigo and Osasuna). 

Despite Valencia's slow start to the season, Michel was under no illusion that this Sunday's trip would be anything but easy. 

“Valencia will be a demanding game. They have only taken one point, but they are a team with very good players. At home, they are very dangerous," Michel said. 

Carlo Ancelotti brushed aside criticism of Real Madrid's unattractive style, saying winning was more important than playing well.

Madrid are unbeaten with five victories across seven games in all competitions this season (two draws), and they got off to a winning start in their Champions League defence on Tuesday, beating Stuttgart 3-1.

In LaLiga, they have won their last two games 2-0 against Real Betis and Real Sociedad, but have still come under fire for their performances.

Ancelotti, however, defended his team's style ahead of their clash at home to mid-table Espanyol.

"Real Madrid fans prefer winning over playing well," he said.

"Ideally you want both, winning while playing an attractive style of football, but our main objective is pleasing our fans who are very demanding, so we will keep our focus on winning as we know that our squad is still far away from ideal form.

"We are not at our best and that is normal in the beginning of a demanding calendar. We will improve as the season starts to get into the important things to play for.

"For the moment we are in, we are doing well." 

The Italian added he was not worried about the poor form of forwards Vinicius Junior and Kylian Mbappe, who are still a work in progress despite playing better each week.

Mbappe has scored five goals already this campaign, while Vinicius also netted in their last league game, and Ancelotti is confident they will be back to their best soon.

"[The criticism] doesn't bother me because I see that the fans are delighted," Ancelotti said.

"You can play better, but the fans are used to our 'rock and roll' football. Not a lot of touches. We try to make the Madrid fans happy. And our game is about intensity, pace... Without wasting too much time in reaching the opponent's goal.

"These are our characteristics. We have players with a lot of strength and speed, especially on the ball, and we have to take advantage of that.

"For me, I believe that beautiful football depends on the characteristics of the players I have. Attacking well, defending well ... playing well on the counter. There are many facets and everyone has their own opinion..."

Barcelona top the LaLiga standings with 15 points, four ahead of Atletico Madrid, Madrid and Villarreal.

Barcelona confirmed that Dani Olmo has been sidelined for up to five weeks with a hamstring injury.

The 26-year-old appeared to suffer muscle discomfort after scoring in Sunday's 4-1 league win at Girona and was substituted in the 61st minute.

Olmo, who signed from RB Leipzig for €55million, missed the first two games of their season due to registration issues but has played in all three since.

He has netted three goals in those appearances, with only Robert Lewandowski netting more so far (four).

Olmo's injury is a blow to Hansi Flick's side as they begin their Champions League campaign against Monaco on Thursday, having already made a perfect start to LaLiga, with five wins from five.

The Spaniard is set to miss at least six games up to the October international break.

The arrivals of Conor Gallagher and Julian Alvarez have energised Atletico Madrid, Diego Simeone said on Sunday.

Gallagher, who joined this summer from Premier League side Chelsea, scored his first LaLiga goal in Sunday's 3-0 home win over Valencia, opening the scoring in the first half.

He is now just the third youngest English goalscorer in the Spanish top-flight (24 years and 222 days), after Jude Bellingham and Mason Greenwood. 

"He came with a lot of enthusiasm, and we needed that kind of player in the midfield because he makes us better," Simeone told a news conference.

"He does not stop giving his best in every game situation in which he participates."

Another new signing, Alvarez, scored in the 93rd minute, also his first goal in the Spanish top flight since joining from Manchester City.

He became the 14th Argentina player to score for Atletico in LaLiga this century. 

"We all needed him to score a goal, for him to be more relaxed, to be connected to what he likes... hopefully the goal will be the first of many," the manager added.

"I imagine that he lives for the goal and the enthusiasm to generate this type of situation. Today he appeared as he always does at the least expected moment at the end of the game when hope seems to be fading and, luckily, he scored."

The Atletico boss added that the strengthened squad, which includes new signings such as Robin Le Normand and Alexander Sorloth, is gelling very well and that allows them to compete at the level they want to.

Hansi Flick heaped praise on Barcelona's teenage sensation Lamine Yamal after he scored a double to help the LaLiga leaders earn a 4-1 victory at Girona on Sunday.

Yamal, who grabbed the spotlight as he helped Spain win their fourth European Championship title in July, scored twice in seven first-half minutes to put them in control.

Dani Olmo and Pedri then secured the win before Cristhian Stuani's consolation and Ferran Torres' late sending-off for a reckless challenge.

Barcelona maintained their unbeaten start to the season, getting their fifth consecutive win at the start of Flick's tenure.

"I'm very happy about Lamine's two goals, he's very young, but he's really incredible, a difference maker at such a young age," Flick told Movistar Plus.

"Having him is key for us not only because of his quality, but he also presses very well high. He combines talent and pressure and that's massive for us. He is outstanding.

"It was a tough game. Girona played well, but we started very well too, and we deserved to win."

Flick's Barcelona top the LaLiga standings with 15 points, four ahead of Real Madrid and Villarreal. Last year's surprise package, Girona, are seventh with seven points.

Barca avenged their two losses to Girona last season, both by a 4-2 result.

It was a dominant performance by the Catalan giants, whose relentless high press was too much for their opponents to handle as they had 20 shots (nine on target), outperforming their 1.82 expected goals.

Now, Barcelona will hope to carry their domestic momentum into the Champions League, where they will face Monaco away on Thursday.

"We have trained very hard for this, and we need to keep going. This last week we have prepared well, but we do it for every game we play because we always want to win, we are in a good moment, and we can't stop," Flick added.

"It won't be easy against Monaco, but we're taking it one game at a time, and we're really excited. We're all looking forward to it."

Atletico Madrid cruised to a convincing 3-0 home win over LaLiga's bottom side Valencia on Sunday, with Conor Gallagher and Julian Alvarez scoring their first goals for the club.

Marcos Llorente and Samuel Lino went close in the first half before Atletico took the lead in the 39th minute, new signing Gallagher finishing into the bottom corner after latching onto a delightful pass from Rodrigo De Paul.

Valencia fought hard for an equaliser, with Javi Guerra's long-range effort going wide, but they were unable to prevent Antoine Griezmann from making it 2-0 after Lino's header fell into his path nine minutes after the break.

Another new recruit, Alvarez, put the icing on the cake with his first goal in the Spanish top flight since arriving from Manchester City, when he slotted home Rodrigo Riquelme's cross in the 93rd minute.

Atletico, who are still unbeaten this season, moved into second place, level on 11 points with Real Madrid and four behind leaders Barcelona. 

Data Debrief: New boys off the mark

Gallagher's opener made him the third-youngest Englishman to net in LaLiga this century, at the age of 24 years and 222 days.

Only Jude Bellingham (20 years and 44 days) and Mason Greenwood (22 years, seven days), both in 2023, have done so at a younger age.

He wasn't the only new recruit to impress on Sunday, though.

Alvarez's goal made him the 14th Argentinian player to score for Atleti since the turn of the century, with no other foreign nation supplying as many unique goalscorers for Los Colchoneros in that time.

Lamine Yamal struck twice in the first half to help Barcelona maintain their perfect start in LaLiga with a commanding 4-1 win at Girona, despite them going down to 10 men.

Yamal gave Barca a two-goal lead with two strikes in seven first-half minutes, dispossessing David Lopez before racing through on goal to curl home his first.

The teenager's second came following good work from Robert Lewandowski, who teed him up to strike through a crowded penalty area and in after 37 minutes.

Dani Olmo extended their lead further with an angled finish after the break, then Pedri tapped home a 64th-minute fourth. 

Girona substitute Cristhian Stuani netted a consolation goal in the 80th minute, six minutes before Barca were reduced to 10 men, forward Ferran Torres receiving a straight red card for a nasty studs-up challenge on Yaser Asprilla.

The Blaugrana's fifth straight win keeps them top of LaLiga on 15 points, four ahead of Real Madrid and Villarreal, while Girona are seventh, eight points off the summit.

Data Debrief: Post-Messi high for Barca

Barcelona have scored 17 goals through their first five games of the season in LaLiga, making a stunning start to life under new boss Hansi Flick.

That is the most they have managed through their opening five matches of a campaign since they also hit 17 in 2017-18.

Prior to the Lionel Messi era, the last time they had netted more at this stage of a season was in 1959-60, when they also scored 17 times.
