Barcelona defender Joao Cancelo faces a spell on the sidelines after suffering knee ligament damage.

Cancelo was forced off after 11 minutes of Barcelona’s 2-1 LaLiga victory at Las Palmas on Thursday.

“Tests carried out on Friday show that first-team player Joao Cancelo has a strained medial collateral ligament in his left knee,” read a Barcelona statement.

“He is unavailable for selection and his recovery will dictate his return.”

Barcelona are in action again on Sunday, against Barbastro in the Copa del Rey, with their next league game at Real Betis on January 21.

Portugal international Cancelo, 29, has made 22 appearances and scored three goals for Barcelona since joining on loan from Manchester City last September.

Ilkay Gundogan scored a stoppage-time penalty to give Barcelona a 2-1 win at Las Palmas and close the gap at the top of LaLiga.

After Barca saw defender Joao Cancelo forced off early on with a knee injury, Munir El Haddadi put the Canary Islanders ahead against his former club.

Ferran Torres equalised soon after the restart before Gundogan slotted in a dramatic late winner from the penalty spot after being pushed over by Daley Sinkgraven, who was shown a red card, to leave Barca seven points behind leaders Real Madrid and Girona.

Brazil forward Vitor Roque was named on the bench after Barcelona received league clearance on the 18-year-old forward’s 40million euro (£35m) move from Athletico Paranaense.

There was an early injury worry for Barca when Cancelo was forced off for some treatment on a knee problem. Although the Portugal defender came back on, he did not last long and was replaced by Andreas Christensen.

Las Palmas soon took the lead in the 12th minute when former Barca striker El Haddadi swept in a low cross from fellow Blaugrana old boy Sandro Ramirez.

Barca looked for a swift response as defender Alejandro Balde got clear down the left, but his ball into the penalty area was cleared behind.

Sandro tested Barca keeper Inaki Pena with an angled drive at the near post following another fluid counter attack by the hosts.

Las Palmas continued to press, with Pena first making a smart save from Javier Munoz’s rising drive before Sandro’s deflected effort from the rebound hit the base of the post.

There was a slight delay at the start of the second half as the bottom of the goal net which Barcelona would be attacking needed some repairs.

Barca threatened when Raphinha fired over from the edge of the penalty area.

The equaliser eventually came in the 55th minute when the ball took a couple of fortuitously defections through the Las Palmas penalty area and fell to Torres, who slotted into the bottom corner.

Frenkie De Jong fired straight at Las Palmas goalkeeper Alvaro Valles after being set up by the busy Gundogan.

Barca boss Xavi made a change for the closing 20 minutes, as Robert Lewandowski was replaced by Joao Felix and Lamine Yamal came on for Raphinha.

Las Palmas went close when Mika Marmol glanced a header wide from a corner before Roque was handed his Barca debut in the 79th minute, coming on for Torres.

Just when it looked like Barca would have to settle for a point, Las Palmas substitute Sinkgraven bundled over Gundogan at the far post as the midfielder looked to head the ball in – and was shown a straight red card.

Gundogan picked himself up and took the resulting penalty himself to calmly slot in a stoppage-time winner before Roque stabbed a late chance wide from six yards.

Barcelona boss Xavi maintains the club will not expect too much too soon from teenager Vitor Roque.

The 18-year-old Brazil forward has been training with his new team-mates after arriving in Catalonia to complete a 40million euro (£35m) move from Athletico Paranaense but has yet to be officially registered with LaLiga.

Xavi, though, played down suggestions of any complications over Barcelona’s financial fair play restrictions and suggested Roque could be involved for Thursday’s match at Las Palmas.

Barcelona put a buy-out clause of 500million euros (£432m) in his long-term contract, which runs until June 2031.

Xavi, though, insists Roque will be given the time needed to establish himself in the side.

“The registration process is the only thing missing. He will be in the squad list. We hope to have him available (for Thursday). I imagine it’s a question of hours,” Xavi said.

“We will take things slowly with him – he is only 18 years old and we can’t shoulder too much responsibility on him.

“He is doing well, is eager and has adapted very quickly to the group and to training, but we will be cautious.”

Barcelona resume LaLiga action away in the Canary Islands following the international break sitting fourth, some seven points off leaders Real Madrid and Girona.

Defender Inigo Martinez is closing in on a return from a thigh problem, so could feature in the the Copa del Rey tie at Barbastro on Sunday.

Marcos Alonso, though, is set for a spell out following surgery to help resolve an on-going back problem.

Xavi feels his players can return refreshed for the challenges ahead in 2024.

“The team has come back very well,” Xavi told a press conference. “There’s no need for words, now it’s time to show it on the pitch. We want to find continuity in our play and results.

“I see how they train, what they are capable of, we have done it with most of them. I am convinced (we can win trophies) and I am very excited to start this year.”

Las Palmas manager Garcia Pimient admits it will be somewhat strange to come up against his boyhood club, having been sacked from his role in charge of Barcelona B in June 2021 – but will have the team fully focused for the challenge.

“It is a special match because I was there for many years. I don’t know how I will feel,” Pimient told a press conference.

“A lot of time has passed since that moment. I have not contacted (Barcelona president) (Joan) Laporta again because I want to thank him because thanks to his decision I am here.”

Pimient added: “We prepared for the match knowing that we would be without the ball for a longer period.

“It will be difficult for us, but we have to be brave and be champions – if we retreat, we will not achieve anything.”

Barcelona defender Marcos Alonso has had surgery to help resolve an on-going back problem, the club have announced.

The 33-year-old Spain left-back has been restricted to just seven appearances for Barca this season, making four starts.

A brief statement on the club’s official website said: “First-team player Marcos Alonso has successfully undergone a procedure to treat his lower back issues.

“The procedure was performed by Dr Amelie Leglise, under the supervision of the club’s medical services, at the Sports Clinic Bordeaux Merignac. The player is out and his recovery will determine his availability.”

Alonso is in his second season with Barca after joining in September 2022 on a free transfer from Chelsea, whom he left by mutual consent with a year left to run on his contract.

His current deal at the Nou Camp expires in June this year, while he is the second Barca player to have back surgery this season following goalkeeper Marc-Andre ter Stegen’s operation last month.

Barcelona defender Marcos Alonso is set to undergo surgery in a bid to resolve the back problems which have limited his appearances this season.

Alonso has started just four games in the current campaign and appeared three times as a substitute.

The 33-year-old has not featured since playing the first hour of a Champions League defeat to Shakhtar Donetsk on November 7.

Barcelona did not give an exact date for the operation but said in a short story on their official website that an update would be provided immediately after the surgery.

Alonso joined Barca for £23million from Chelsea in September 2022 following a hugely successful six-year spell in London, during which time he helped the Blues win the Champions League, Premier League and FA Cup.

The European Super League's pledge to stream all matches for free is unsustainable and merely a ploy to coax fans into supporting the project.

That is the view of finance expert Dan Plumley, who does not see how a breakaway competition could offer enough prize money to earn the support of clubs while showing games for free. 

Despite a backlash from fans, players and media thwarting the Super League's attempted launch in 2021, the project reared its head again this week with a reworked format being announced.

After the European Court of Justice (ECJ) ruled FIFA and UEFA "abused a dominant position" in blocking the Super League two years ago, the competition's organisers, A22 Sports, revealed a new format for the tournament, which is still supported by Real Madrid and Barcelona. 

The plan features promotion and relegation across three tiers and also includes a promise to make all games free to stream, but Plumley doubts whether that is possible.

"Everything we've seen throughout history would point to the fact that won't be sustainable, which is where the finances and the distribution models get interesting," he told Stats Perform. 

"We've seen the proposed format of the new ESL but we've not seen the financial distribution mechanisms, we've not seen where the money's coming from and if you are going to promote a free-to-air model through a streaming service, that obviously looks good for the fans.

"But at some point you have to have some form of broadcaster to be able to generate prize money and to generate the finances of the competition. 

"Everything I've seen throughout the years would suggest that you can't go that long without a decent broadcasting deal or big commercial and sponsorship partnerships." 

Asked whether the promise of free coverage was purely intended to get fans onside, Plumley added: "Yeah, for sure. 

"You've probably made the most relevant point there, which is how much people are paying currently for sports subscription content. 

"Talking from a basis of us being located in the UK, it's not cheap. If you want a Sky Sports subscription, a TNT Sports subscription, the Amazon one… it does become quite costly for the fans. 

"So to have something that is free at the point of consumption is obviously a hook for fans to come on board with it. 

"I think we've clearly seen the backlash in the UK with the English clubs and many English fans. 

"Even if it is free-to-air and dependent on the clubs that would be involved, I think some would still turn around and say: 'No, thank you very much. Even if it's free, I'm not interested'. 

"But there is a whole range of international fans out there that follow European football and follow some of these clubs. Maybe some of those are interested. 

"You look at it through your own lens, but you also have to look at it through the lens of others. Obviously it's a ploy to try and get some positivity on board by offering it free-to-air."

Plumley said the only way the project could succeed financially with a free-to-air model was through the potential involvement of a state wealth fund.

"I think where you might see some shift in the future, and this might start to make it bigger than Europe, is will we see sovereign state wealth funds or private equity consortiums get involved with the financing of the competition, to enable them to show some free-to-air content?" Plumley said.

"In the 2021 project, it was supposed to be financed by JP Morgan and we saw that American influence, we've seen an explosion in Saudi Arabian football in the last couple of years. 

"Do one of those other big players in the market get involved in the future? I think all those questions are a little bit up in the air at the minute. 

"At some point, you have to start talking about broadcasting deals because there's only so much free-to-air content you can give away if you're going to be putting a load of prize money on the table."

The European Super League needs English clubs more than they need the breakaway competition, says football finance expert Dan Plumley.

The European Super League was initially announced back in April 2021, with 12 of the continent's biggest clubs announcing their intention to join. Manchester United, Manchester City, Liverpool, Arsenal, Chelsea and Tottenham all agreed to participate.

However, a fan backlash eventually forced nine of the clubs to back down, including all six English teams, and the Super League looked to be a thing of the past.

A ruling this week may have given it a second life, though, with the European Court of Justice (ECJ) in Luxembourg deciding FIFA and UEFA "abused a dominant position" in blocking the Super League.

A new proposal was swiftly announced, but all six English clubs invited to join rejected the request.

Plumley believes the Super League would need the support of English clubs to get off the ground, though he did warn their involvement could still be a possibility despite the heavy opposition seen after the initial launch in 2021.

When asked if the Super League required the English clubs' involvement, Plumley told Stats Perform: "Yes, I think that's absolutely the way to position it at the moment.

"And I'm not saying that it would never happen. The Premier League clubs don't really need to go following the Super League, but the Super League would be better with English clubs.

"I don't think the Super League idea is ever going to be fully dead in the water. I think we'll see it in some way, shape or form, and maybe it will happen.

"When you're talking about lots of money on the table, a lot of clubs will often look for the best deal on the table and if that is a European Super League in the future, that's when heads might start to be turned.

"But the English situation is a bit of a problem for them, because you're talking about wanting the biggest clubs in the world to be part of it. And there are some very big English clubs that have already ruled themselves out."

Spanish giants Barcelona and Real Madrid are two of the clubs spearheading the Super League project, with the latter's president Florentino Perez hailing the ECJ's ruling as a "great day for the history of football".

Plumley feels the poor financial situations of Barcelona and Madrid are a key reason behind their Super League support, as well as the recent power shift towards the Premier League in terms of revenue and talent.

"I think, certainly for them, the driving force over the last couple of years has been financial," Plumley stated. "We know the financial situation at Barcelona has not been great. We know Real Madrid have had problems as well.

"I think the other thing with those two clubs that we've seen is a real stubbornness to dig their heels in. They wanted to be proved right and in a way that verdict does prove them right. Part of their argument was that UEFA and FIFA were acting unlawfully by blocking it.

"I think what's hurt Barcelona and Real Madrid along the way is all the other clubs that have moved away from the project.

"I think it's symptomatic also of Barca and Real's position in Spain. Yes, they are dominant, but where are they seeing the growth?

"I don't think they're seeing as much growth as potentially the Premier League's got to offer and those are little things where it becomes about, 'well, now I'm going to look at my own self-interest'. You can see how they've tried to leverage that through the Super League.

"At the end of the day it comes down to finance, and certainly in the early stages of it, it was all about money for those two clubs. Don't get me wrong, it probably still is, but I think a lot of it then was they felt like they needed to see the case through because they dug their heels in."

Sergi Roberto came to Barcelona’s rescue with a brace to finally see off rock-bottom Almeria 3-2 as the LaLiga champions returned to winning ways.

The hosts looked set to stretch their winless run to four games in all competitions after twice being pegged back by opponents still in search of their first league win of the season.

But the 31-year-old latched on to a through-ball from Robert Lewandowski in the 83rd minute to grab the points which take his side back within four points of second-placed Real Madrid.

Xavi’s men were overwhelming favourites as they aimed to shrug off their recent poor run, and they started on top.

Joao Felix floated a free-kick just over the crossbar then Sergi Roberto saw his first chance well saved by busy Almeria goalkeeper Luis Maximiano.

Joao Cancelo was next up with an effort that he drilled straight at the keeper, before Fermin Lopez headed over from Ilkay Gundogan’s pinpoint cross.

Sergi Roberto blasted over from long-range on the half-hour mark before Barca finally made their seemingly inevitable breakthrough three minutes later when Ronald Araujo’s deflected effort fell to Raphinha who fired it into an empty net.

Lewandowski almost doubled Barcelona’s lead before Almeria snatched their chance to level four minutes before the break, Leo Baptistao lofting the ball over advancing Barca keeper Inaki Pena and surviving a VAR check.

Baptistao had a chance to put his side in front before the break but dragged an effort wide and normal service resumed early in the second period with substitute Ferran Torres and Lewandowski both denied.

Sergi Roberto grabbed his opener on the hour when he met Raphinha’s corner with a header at the near post to put Barcelona back in front.

But the lead lasted barely 10 minutes before the hosts were undone by a calamitous error by Pena, who dropped the ball in a collision with Araujo, allowing the alert Edgar Gonzalez to slide it into an empty net.

The hosts responded well, Araujo making up for his part in the equaliser by heading just wide, before Gundogan contrived to somehow miss his chance with the goal at his mercy.

Sergi Roberto finally grabbed what proved to be the decider in the 83rd minute when he ran on to Lewandowski’s ball through the middle to seal three hard-earned points.

Lewandowski almost added a fourth and the captain was denied a hat-trick deep into added time when his effort rattled back off the woodwork.

Barcelona midfielder Pedri faces a short spell on the sidelines after suffering a muscle injury in training.

The 21-year-old Spain international, who has started eight LaLiga games this season, will definitely miss the champions’ clash with bottom side Almeria on Wednesday.

An update from the club read: “First-team player Pedri got a knock in training and has a slight muscle injury. He is ruled out of selection and his recovery will determine his return.”

Barcelona boss Xavi Hernandez is confident his side can close the gap on LaLiga’s leaders but will need to cut out the errors.

Last season’s champions are nine points off the top after winning just one of their last four games in the competition.

Barca are currently third, trailing second-placed Real Madrid by seven points with Girona – who beat their Catalan rivals earlier this month – leading the way.

Xavi told reporters at a press conference: “The conviction in both areas is marking our season a little and that is what needs to be fixed and improved to be competitive in all competitions.

“Yes, I see it as recoverable but, of course, we have to be competitive rather than fail ourselves. In the end, what is costing us is our mistakes.”

Barca were held to a 1-1 draw at Valencia in their last outing but will be expected to get back to winning ways as they host bottom side Almeria – who are yet to win a game – on Wednesday.

Xavi said: “It is a very important game for us. We need a victory for the feelings of confidence, three points and to continue believing.

“There is still the league. There are still mathematical possibilities to win it. It has become difficult for us, but we have to go step by step and tomorrow is an important step.

“We have been playing good football but we need to win games. We need the fans and need to play that complete game that we have been missing until now.”

Xavi also gave his thoughts on his side being drawn against Serie A winners Napoli in the last 16 of the Champions League.

Like Barca, Napoli are finding defending their crown tough going.

“We are playing against the current Italian champions and I think it’ll be difficult,” said Xavi. “I think we have a 50 per cent chance because they are in a similar situation to our own.”

Despite their predicament, Almeria, who are eight points from safety, are hoping to make life difficult for the champions.

Head coach Gaizka Garitano, whose team claimed a goalless draw with Mallorca in their last outing, said: “We’ve competed on pitches where it’s very difficult to win.

“We’re going to go all out to obtain a good result with courage and desire to compete but, if we don’t give 100 per cent, they can hurt us.”

Napoli manager Walter Mazzarri hailed a “thrilling” match in prospect after his side were drawn against Barcelona in the last 16 of the Champions League.

The Serie A champions will face their LaLiga counterparts in February after progressing from a tough group which contained Real Madrid, Braga and Union Berlin.

It took a victory on the final matchday against the Portuguese side before qualification was confirmed.

And their reward is a meeting with a Barca side who last played at this stage of the competition in 2021 having been eliminated in the group stage in each of the last two seasons.

Mazzarri replaced the sacked Rudi Garcia in November with two games of the group to go and helped salvage their campaign after dropped points against Real and Union had placed their future in the tournament in jeopardy.

“I said after the match against Cagliari that all the teams who have qualified for the round of 16 are strong and therefore any draw would be difficult,” said Mazzarri.

“This one against Barcelona is especially difficult. For Napoli it will be a thrilling prospect.”

Mazzarri could turn to youngsters Giovanni Simeone, Alessandro Zanoli and Gianluca Gaetano for Tuesday’s Coppa Italia last-16 meeting at home to Frosinone, with the opportunity to rest more established players against the side sitting 13th in Serie A.

Striker Victor Osimhen is one of the players likely to sit out, with either Simeone or Giacomo Raspadori coming in to deputise.

Piotr Zielinski, Mathias Olivera and Eljif Elmas all missed the recent meeting with Cagliari, but Mario Rui could return.

Frosinone boss Eusebio di Francesco called on his side to be more clinical in front of goal against the champions after they went down 2-1 to Lecce on Saturday.

“We have to be a little more concrete and, when the team plays interesting patterns, it’s good,” he said.

“But we have to be more determined and aggressive in front of goal.”

Barcelona lost further ground at the top of LaLiga as Valencia fought back to draw 1-1 at the Mestalla.

Joao Felix had put Barca ahead early in the second half, but Hugo Guillamon fired the hosts level with 20 minutes left.

The draw left Barca in third, but having played a match more than both Real Madrid and leaders Girona as the pressure continues to increase on manager Xavi.

Valencia, who had lost three of their last four league matches, created an early chance when Roman Yaremchuk spun to fire goalwards, but Barca keeper Inaki Pena made a smart save down to his left.

At the other end, Robert Lewandowski – without a goal in his last three away LaLiga games – had a shot deflected wide, although the ball had gone out of play in the build-up.

Pena was again called into action in the 16th minute as he got down to clear Cristhian Mosquera’s close-range header.

Valencia keeper Giorgi Mamardashvili saved Lewandowski’s drive from the edge of the penalty area in a lively spell.

The Mestalla crowd were soon calling for a penalty when Pepelu went down under a clumsy challenge from behind by Raphinha, but the referee was not interested.

Mamardashvili had to be alert to parry away an acrobatic effort from Lewandowski before Pedri flashed a rising drive over from the edge of the Valencia box.

Valencia winger Fran Perez hit a low ball through the Barcelona six-yard box which just needed a touch to turn it into the net.

Barcelona, beaten 4-2 at home by Girona last weekend, looked to step up the tempo at the start of the second half, with Ilkay Gundogan sending a first-time shot wide before the deadlock was broken in the 55th minute.

Frenkie De Jong chipped a ball down the right for Raphinha, who cut a pass back through the six-yard box for Felix to tap in at the far post.

Tempers threatened to boil over just after the hour mark when Perez flew into a challenge on Gundogan, and was swiftly shown a yellow card.

Mamardashvili produced a fine low reaction save at his near post after Raphinha had pulled the ball back from the goalline to rifle in an angled drive.

Valencia were back on level terms with 20 minutes left.

Guillamon fired a shot into the top-right corner after Barcelona had failed to clear a high ball into the penalty area from Perez, who was ruled onside following a VAR review.

Mamardashvili made another reflex stop when Barca substitute Ferran Torres latched onto an angled ball in from De Jong.

Barcelona pushed for a winner, but Raphinha was denied at the far post by a brilliant block from Yarek Gasiorowski on the line after Mamardashvili had saved the Brazilian’s initial effort.

Xavi insists he does not feel “alone” despite the pressure building on the Barcelona coach.

The Blaugrana have suffered back-to-back defeats heading into Saturday evening’s encounter with Valencia.

Xavi’s men sit fourth in the table having been beaten 4-2 at home by La Liga leaders Girona last Sunday, leading to speculation around the former playmaker’s long-term future at Camp Nou.

However, Xavi is confident he has the backing of the club’s leadership and rated the fans’ support for his team as a “perfect 10”.

“I never feel alone. I feel like I have support and strength and I feel that we can have a great season,” he said at his pre-match press conference in quotes reported by the club’s X account.

“The fans are behind the team, they are a perfect 10. They know that we will give everything.

“We have a fantastic relationship, with the president (Joan Laporta), with (sporting director) Deco, with (vice-president) Rafa Yuste… I believe more than ever in the project and in what we are doing.

“The club needs stability. We are a winning project. We are the defending La Liga and Super Cup champions.”

Barca had bounced back from home defeat in the ‘Clasico’ against Real Madrid with three wins and a draw from their next four league games before the Girona setback.

A team showing seven changes then also lost 3-2 away to Royal Antwerp on Wednesday night in the Champions League, but with qualification for the last 16 already assured.

Barca go into the match at the Mestalla seven points adrift of Girona, five behind Real and below Atletico Madrid on goal difference.

They remain without long-term injury victim Gavi, who is out with a cruciate ligament tear. Goalkeeper Marc-Andre ter Stegen and defender Marcos Alonso, who are both suffering with back injuries, remain out of the squad heading into this weekend.

Valencia have not won any of their last four matches in La Liga, losing three and drawing one, but their striker Fran Perez was in bullish mood ahead of Barca’s visit to the Mestalla.

“We are working hard to hurt Barca and it’s going very well. We’re really looking forward to it,” he told the club’s in-house radio station.

“If we beat Atleti at home 3-0, why can’t we beat Barca at Mestalla? It’s going to be a very competitive game. The game is all about keeping a clean sheet and making the most of the chances we get. We can’t get distracted in any action.

“At Mestalla we are a very difficult team to beat. We have to be calm and compete well and I’m convinced that we’ll have a very good game.

“Our fans are very important and they are our 12th man. We are going to have a great game not only for us, but also for the fans, who deserve it.

“The tickets being practically sold out shows how the fans support us and we must respond with the highest possible level of demand. We must give everything for the club and for our fans.”

Valencia are 11th going into the weekend, with five wins, four draws and seven defeats from their 16 matches so far.

Barcelona finished on top of Champions League Group H despite slipping to a shock 3-2 defeat to Royal Antwerp in a dramatic contest at the Bosuilstadion.

After the first half had seen Arthur Vermeeren’s early effort for the hosts cancelled out by Ferran Torres, former Tottenham striker Vincent Janssen restored the lead for Mark van Bommel’s Antwerp 11 minutes after the break.

Barcelona then hit back via Marc Guiu in stoppage time, only for George Ilenikhena to reply moments later to wrap up a historic win for the Belgians, who had lost each of their previous five games in what was their debut Champions League group campaign.

Barca had gone into the match with qualification for the last 16 secure, and retained top spot ahead of Porto – who beat Shakhtar Donetsk 5-3 – thanks to a superior head to head record.

It was the second time in four days that Xavi’s men were beaten, following Sunday’s 4-2 LaLiga loss at home to Girona.

With a starting XI showing seven changes from that game, Barcelona found themselves a goal down in the second minute when a mistake at the back was punished by 18-year-old midfielder Vermeeren.

Receiving a pass from goalkeeper Inaki Pena in the Barca box, Oriel Romeu inadvertently diverted the ball to Vermeeren, who fired into the net.

Janssen then saw his shot on the turn comfortably dealt with by Pena, and sent a further effort off target.

Having struggled for rhythm, Barca were then back on level terms in the 35th minute via a counter-attack that ended with Lamine Yamal playing a fine pass and Torres sweeping the ball past Jean Butez.

Antwerp had the ball in the net again five minutes into the second half but Janssen’s finish was disallowed for handball, and Yamal struck the bar at the other end moments later.

A dramatic few minutes then continued with Barca’s Sergi Roberto being shown a red card for a challenge on Mandela Keita before the decision was overturned via VAR, before Antwerp did regain the lead.

Romeu was again guilty of sloppiness, being dispossessed near his box by Alhassan Yusuf, and he laid the ball to Janssen, who struck into the corner of the net.

Xavi responded with a triple substitution on the hour as Ilkay Gundogan, replacing Romeu, Joao Cancelo and Pedri came on.

Further Antwerp pressure saw Chidera Ejuke put a shot from distance over and Soumaila Coulibaly head wide, either side of a Pedri attempt being blocked.

Barca pushed to hit back late on and equalised in the first minute of stoppage time when Guiu, who had come on for Robert Lewandowski, headed in a Gundogan free-kick.

But one of Antwerp’s substitutes then had the final say as Ilenikhena – Guiu’s fellow 17-year-old – beat Pena a minute later to seal a famous result.

Xavi believes he is on the way to creating a “great Barcelona” side but he wants improvement as they close their Champions League group stage at Royal Antwerp.

Barca are already guaranteed a place in the last 16 and are virtually assured top spot in Group H, barring some unlikely results.

The Spanish club have not been at the top table of European football for a while, having last won the Champions League in 2015, but Xavi, who was a key player in the side that dominated the game a decade ago, can see progress.

“We want to end the group stage having done what we need to do,” he said on Barcelona’s website.

“We have to be much more effective. We create a lot of chances to win games earlier. We have to be better in front of goal, but also improve our defensive robustness.

“We have to show consistency to achieve targets and trophies. We are on the way to creating a great Barca side.

“The team is together and a close-knit group.”

The Belgian side have lost all five of their group games so far, but Xavi still respects the team managed by his former team-mate Mark van Bommel.

“They are a good team and Van Bommel is doing a very good job, and he wants to leave a mark playing football based on teamwork,” Xavi added.

“We will decide which players will feature after training and prior to the game, but it is a good chance to give opportunities to young players and others who haven’t played that much.

“Logically we will make changes.”

Inaki Pena is almost certain to continue in goal after Marc-Andre ter Stegen had back surgery last week.

“The injury to Ter Stegen is not good news,” the goalkeeper said. “It makes me proud to be playing in this shirt.

“I have trained every day thinking that this day would come because you never know what can happen. At a club like Barca you can’t relax for a single day.

“I have been training for a long time with Ter Stegen and it is a pleasure to be able to learn from one of the best players in the world.

“Picking things up from him has made me a better goalkeeper.”
