Jurgen Klopp concedes it would be "really strange" if Luis Diaz was able to immediately show his best form for Liverpool but is "really happy and excited" about what he can bring to the Reds.

The Colombia winger joined from Porto after signing a long-term contract at Anfield in a deal reported to be worth an initial £37.5million with a further £12.5m in add-ons.

Diaz was a man in demand with Liverpool reportedly beating off competition from Premier League rivals Tottenham, while Everton had previously been linked with his signature.

At Liverpool, Diaz joins an already stacked attacking line-up that includes Mohamed Salah, Sadio Mane, Roberto Firmino and Diogo Jota.

Klopp accepts there is likely to be a bedding-in period for his new signing but has no doubt he can make a huge contribution at the club.

"Luis, let me say it like this, if he now came and stepped on the pitch and was immediately at his best and playing better than everyone else it would be really strange," Klopp said ahead of Liverpool's FA Cup fourth-round tie with Cardiff City.

"He needs time to adapt, but that doesn't mean I speak about four or five months, I haven't even seen him yet in training so maybe we should wait a little bit.

"But I'm really happy and excited about the signing, it's a really good sign that we work on all fronts to improve this team, that's how it always is in football. Obviously how it works is we have to be successful now and in the future. He can help with both that's a really good thing.

"We signed him because we like pretty much everything about him. I followed him now for a while not only since we played them twice in the Champions League. 

"He has the speed, skillset, and character to have a really good career. We want him to have that career with us. 

"I'm really happy we could get him in now, he can help us, we can help him. His story so far is a special one. Now he's one of us, we can't wait to welcome him here."

Klopp's options are set to be further boosted this weekend, with Naby Keita back from Africa Cup of Nations duty. Thiago Alcantara has also been back in training having been absent since December due to a thigh issue but a chest infection may curtail his chances of a return, while Divock Origi could be in contention after a knee injury.

And in further good news, talented midfielder Harvey Elliott is set to play against Cardiff this weekend after five months out as a result of a horrific fracture-dislocation of his ankle sustained against Leeds United.

"Very impressed with his rehabilitation. Harvey was the perfect client, he did pretty much everything we told him," Klopp added.

"He is in a good place, we have to see if it's right for him to start or come on but he'll definitely be in the squad for the Cardiff game.

"He has now step-by-step to get back to his best but he's close, very close."

Jesse Lingard remained at Manchester United beyond the January transfer window, but the England international's long-term future at Old Trafford is far from certain.

After struggling for appearances this term under Ole Gunnar Solskjaer and then Ralf Rangnick, Lingard's time at United may be reaching its natural conclusion.

A number of teams have been tipped to move for the 29-year-old at the end of the campaign, at which point he will officially become a free agent.

TOP STORY - LINGARD ON JUVE'S RADAR

Juventus have been unable to agree fresh terms with Paulo Dybala and, according to Calciomercato, plans are already in place to bring in a replacement in the next window.

The report claims that Juve are big fans of Lingard, despite his limited playing time this season, and will attempt to see off competition for his signature.

Newcastle United and West Ham, where Lingard spent a successful period on loan in 2020-21, have also been tipped to move for the United academy product.

ROUND-UP

- Barcelona have taken the first steps towards signing soon-to-be free agent Marcelo Brozovic from Inter at the end of the season, according to Calciomercato. 

- Transfer expert Ekrem Konur claims that Manchester City are confident of agreeing fresh terms with Ilkay Gundogan amid interest from England, Spain and Germany.

- Juve have recently been tipped to move for Nicolo Zaniolo, and Calciomercato suggests that Roma will allow the midfielder to leave should his €40million valuation be met.

- Marco Asensio is open to extending his contract with Real Madrid beyond the end of next season, despite not being first choice. That is according to Goal.

- Douglas Costa has agreed to join Los Angeles Galaxy from Juventus on an initial 18-month contract, claims Fabrizio Romano, with a deal set to be confirmed early next week.

Jesse Lingard clarified that his absence from Manchester United training was due to the club advising him to have time off for "personal reasons".

Lingard was strongly linked with a move away from Old Trafford throughout the January transfer window due to a lack of first-team football and the fact his contract will expire in June.

Interim manager Ralf Rangnick confirmed he told Lingard he could leave if an agreement could be made with another club, but no such deal was struck.

Rangnick revealed on Thursday that Mason Greenwood's unavailability "until further notice" was a factor in United's decision to keep Lingard at the club.

But the German confirmed Lingard would not be involved against Middlesbrough in the FA Cup on Friday after "he asked for a couple days off to clear up his mind".

This led to some critics questioning Lingard's commitment and others accusing United of pandering to players, with Rangnick also stating Edinson Cavani had been granted an extra couple of days off following his return from international duty.

But Lingard has hit back, insisting the club told him to take a step back.

He wrote on his official Twitter account: "The club advised me to have time off due to personal reasons!

"But my headspace is clear and I'll always be professional when called upon and give 100 per cent."

Among current United players to make at least one Premier League appearance this term, no one has been on the pitch for fewer minutes than Lingard (88).

Niklas Sule is set to leave Bayern Munich as a free agent at the end of the season, but Julian Nagelsmann has no ill feelings towards the defender.

Sule was offered a new deal by Bayern but has instead decided his future lies elsewhere.

The centre-back has missed just two Bundesliga games this season and will surely be highly sought after as a free agent.

Nagelsmann acknowledged that his initial response was to wonder if he had done something to aggravate Sule, whom he also worked with at Hoffenheim, but he does not believe that to be the case.

Indeed, he insisted his relationship with Sule remains strong and he is excited to see what the future holds for the Germany international.

"I know his reasons, but I'll keep them between us," Nagelsmann said in a news conference ahead of Saturday's clash with his old club RB Leipzig. 

"I would have liked to have kept Niklas here, so he plays a lot. There is absolutely nothing going on between us. Decisions like his are part of football.

"There will be players that I'm happy with, and sometimes players leave that you are not happy with. 

"I wondered if I had done something wrong or could have done better. I think that's part of reflecting.

"Niklas will be with us until the summer. Then I wait with the same excitement as everyone else where he will go and how he will fare at his new club."

Pierre-Emerick Aubameyang believes he can become a Champions League winner with Barcelona and expects Xavi to use him as a number nine.

Released by Arsenal after a turbulent end to his Gunners career, Aubameyang described coming to Barcelona as "the opportunity of my life".

The 32-year-old forward has been brought in to add experience and goals to a Barcelona team who have been short on both counts this season.

For all the talented youngsters being brought through, Barcelona sit fifth in LaLiga after 21 games, having won only nine times so far.

Aubameyang follows Ferran Torres and Adama Traore in leaving the Premier League for Camp Nou in recent weeks, and while Barcelona have already been knocked out of this season's Champions League, the latest addition to Xavi's squad sees no reason why they should not be successful there next term.

"Barca is a great club that has to win the Champions League. That's why I came to Barca," Aubameyang said at his presentation.

"It's an opportunity to win the Champions League, and I'm here to do everything we can to get back into the Champions League and then go out and win it.

"It's true that I've not played for a little while, but in my head everything's very clear, and I'll be ready soon to play and help out, and I know we're going to go back to the top little by little.

"I have spoken with the coach. He sees me playing as a number nine, and I will be ready very soon to play there. If he needs me on the wing, there will be no problem with that."

Barcelona have scored just 32 goals in LaLiga so far in 2021-22, the seventh-most in the competition. This is despite them having the second-highest expected goals (xG) total of 36.9 (beaten only by Real Madrid's 44.58).

The xG metric looks at the quality of a team's chances, rather than the quality of finishing, and by bringing in Torres and Aubameyang, Barcelona will hope they can begin to make better use of their opportunities.

Aubameyang said the move had felt "like a dream" and he was "not ready to wake up", but the mention of Erling Haaland from reporters at his presentation may have been a momentary reality check.

For all that Aubameyang may bring this season, Barcelona are already looking for newer additions, and 21-year-old striker Haaland has been long linked with the club.

The Norwegian is starring for another of Aubameyang's former teams, Borussia Dortmund, and Barcelona president Joan Laporta ushered away enquiries at Thursday's presentation when Haaland's name was raised.

Aubameyang has scored seven goals this season at one every 159.29 minutes, while Haaland has hit 23 for Dortmund, finding the back of the net every 70.35 minutes.

"Today we're occupied and very excited with Aubameyang," Laporta said. "In June, we will strengthen the squad. We're on the right track.

"Right now, we're occupied with the present and the immediate. What we want is to try and compete for the league, and also win of course the Europa League, which are the competitions that remain today.

"That's the state of affairs today. With regard to players, it's of course work for the technical staff. There are interesting players, and we will evaluate the opportunity to incorporate those, but I'm not going to talk about that now."

Manchester United interim manager Ralf Rangnick explained Jesse Lingard was not allowed to leave in January partly due to Mason Greenwood's unavailability.

Greenwood was arrested on Sunday on suspicion of rape and assault following allegations made on social media.

He was then further arrested two days later on suspicion of sexual assault and threats to kill. Greenwood, who has not publicly commented on the allegations, was released on bail "pending further investigation" on Wednesday.

United confirmed on Sunday that the 20-year-old will not train or play for the club "until further notice", with their statement stating they do "not condone violence of any kind".

Lingard had been hoping to leave Old Trafford in search of regular first-team football, having only made two starts and 12 substitute appearances in all competitions for the Red Devils this season.

Newcastle United and West Ham – where he enjoyed a successful loan spell last season – were both reportedly interested, however United refused to sanction a move, with Rangnick outlining their reasons ahead of Friday's FA Cup fourth-round tie with Middlesbrough.

"Three weeks ago, Jesse didn't want to leave, then he changed his mind," Rangnick told reporters. "I had a chat with him 10 days ago and could fully understand why he wanted to leave for game time, for his future and also for the World Cup.

"I said in case he found a club he wanted to play for and also found a solution with our club, I would allow him to leave. But obviously with all the developments in the last [few] days, things changed a little, and we also had no agreement with any other club.

"So at one stage we had to take a final decision with the board, and we decided to keep Jesse until the end of the season."

When pressed further as to whether Greenwood's arrest had been a factor, Rangnick added: "In a way, yes, but in the end the board told me they couldn't find an agreement with those clubs interested in him, so with the window closing on Monday evening, in the afternoon the board said they would rather he stayed. 

"For me it was a decision I could fully understand and accept. It was two things, we had the problem with Mason Greenwood, being without a player for the time being who has played regularly, and then on the other hand the club couldn't find an agreement with any other club."

The German coach also confirmed Lingard had requested a couple of days to "clear up his mind", with the 29-year-old set to miss the Middlesbrough match.

Despite the situation surrounding Greenwood, Rangnick felt United were able to have a "normal" week of training.

"We had a good and normal week of training, five sessions including today," he said. "Obviously I suppose [Greenwood] was a topic within the team, but they are all human beings and Mason was part of the group before our break.

"It was a good week of training, we could train in normal circumstances and we are looking forward to the game."

Pierre-Emerick Aubameyang is holding out hope that he can be reunited with contract rebel Ousmane Dembele in the Barcelona team.

Dembele has resisted calls to sign new terms to extend his contract, that runs out at the end of this season, and that stance has seen him exiled from matchday squads.

Barcelona were frustrated they could not sell Dembele in January, amid reported strong interest from Paris Saint-Germain, and they face losing him on a free transfer unless he can be persuaded to commit.

The 24-year-old French winger played with Aubameyang at Borussia Dortmund in the 2016-17 season, and they remain close.

"I've got to tell you the truth, he's training really well," Aubameyang said at his Camp Nou presentation on Thursday.

"If anything, as a friend of Ousmane, I hope he and the club will find a solution.

"Knowing Ousmane as a player, he's a fantastic player of course. Like I said before, I hope that he finds an answer. This is something I can't decide."

Aubameyang joined the LaLiga giants after being released from his contract with Arsenal, agreeing a deal until June 2025 with an option to cut ties earlier, in June 2023. The deal includes a buy-out clause of €100million.

Barcelona president Joan Laporta said Aubameyang had made "a sacrifice" to come to Barcelona, seemingly firming up the recent suggestion he has taken a pay cut.

"You know that once we have a more healthy financial situation, we will help you as you are helping Barca now," Laporta told Aubameyang.

The 32-year-old Barcelona new recruit fell out of favour with Arsenal manager, Mikel Arteta, resulting in him losing the captaincy at Emirates Stadium and being left out of recent squads.

Aubameyang was accused of failing to show the right level of commitment, and was punished for disciplinary breaches.

"He wasn't happy and that was it," said Aubameyang, when asked about Arteta. "I can't say anything else because that's what happened. I'm better this way.

"There were some complicated months. Sometimes football is like that. On my behalf, I never wanted to do anything bad, but OK, now I have to put this behind me."

The Gabon international added: "I'm very happy and very grateful to you, Mr President, for signing me. This is an honour for me to be here, to play for Barca, so I'm very happy.

"I hope to score an awful lot of goals for Barca. I've always had the dream to play in LaLiga. I think this is an incredible opportunity that I've dreamt of since I was a child.

"This is the opportunity of my life."

Manchester United's search for a new full-time manager continues.

Ralf Rangnick has been in interim charge at Old Trafford since Ole Gunnar Solskjaer's dismissal in November.

English powerhouse United have failed to win any silverware since 2017

TOP STORY - MAN UTD CONFIDENT ON LANDING POCHETTINO

Manchester United have renewed confidence that they will land Paris Saint-Germain head coach Pochettino as their new boss, claims The Mirror.

The Argentine is understood to be United's number one candidate for the permanent role.

Footmercato claims Pochettino is tired of the constant criticism he has received at PSG and will not stay beyond this season.

ROUND-UP

- Manchester City are on verge of tabling an offer to Borussia Dortmund's Erling Haaland to make him one of the highest paid players in the Premier League, according to Todofichajes.

- The Sun reports that Arsenal are planning for a £180 million off-season spend, with Real Sociedad's Alexander Isak, Everton's Dominic Calvert-Lewin and Wolves' Ruben Neves among their targets. However, this is dependent on Arsenal finishing top four.

- Chelsea will open pre-contract agreement talks with Barcelona's Ousmane Dembele after he failed to make a deadline day move, claims Sky Sports. 

- Chelsea are also eyeing a move for Real Madrid defender Eder Militao as they plan for the departures of Andreas Christensen and Antonio Rudiger, according to AS.

- Juventus and Milan are leading the race to land Roma's Nicolo Zaniolo reports Sky Italia. Roma are looking to cash in Zaniolo in the off-season, with Tottenham also interested.

Erling Haaland would suit playing for Jurgen Klopp at Liverpool, according to Ruud Gullit. 

Borussia Dortmund striker Haaland is expected to be one of the most in-demand players when the transfer market re-opens in the close season. 

The 21-year-old reportedly has a clause in his contract that means he will be available for €75million (£68m), a fee that looks like a bargain given his goalscoring exploits. 

Manchester City are believed to be the frontrunners for his signature, while Manchester United, Liverpool and Real Madrid have also been heavily linked. 

Gullit does not believe United will be able to beat the competition to Haaland's signature, with the former Netherlands international claiming Liverpool will be the best place for the Dortmund star to take the next step in his career. 

"I see him in England, but I don't think he'll go to Manchester United," Gullit told Bild. 

"City would be good for him because of Pep Guardiola. But Jurgen Klopp and Liverpool would also be great. What Jurgen has done with the club is unbelievable. You just have to love him, and he's always hungry. That suits Haaland. 

"In Spain, only Real Madrid is an option. These are the three clubs that will be in the running for Erling." 

Since his debut for Dortmund on January 18, 2020, Haaland has been involved in 97 goals (80 scored, 17 assisted) in 79 appearances in all competitions for the club. That is over double the number of goal involvements Sadio Mane has had for Liverpool in the same time frame (43) and 14 more than Mohamed Salah, who has played in 18 more games.

Another player linked with a move to the Premier League is Bayern Munich defender Niklas Sule. 

Sule will be out of contract at the end of the season and will be available on a free if he does not agree to a renewal with Bayern beforehand. 

Should the Bundesliga champions need to dip into the market to reinforce their squad, Gullit believes Juventus' Dutch defender Matthijs de Ligt would be a good solution. 

"Matthijs has experienced and learned a lot at Juventus. He could make a very good contribution to Bayern," he said. 

Dele Alli made the right decision to leave Tottenham for Everton and can return to his very best at Goodison Park, according to former Spurs defender Jonathan Woodgate.

Alli's seven-year spell at Tottenham came to an end on Monday, leaving for Merseyside in what is said to be an initial free transfer.

Everton will reportedly be obliged to pay £10million for the midfielder after he makes 20 appearances, with subsequent performance-based add-ons that may take the eventual figure as high as £40m.

After signing for Spurs in January 2015, but initially staying at MK Dons on loan, Alli swiftly became a key player under Mauricio Pochettino.

He has failed to maintain that form in recent seasons, though, and Woodgate, who played for Tottenham between 2008 and 2011, believes Alli can return to the peak of his powers under new Toffees boss Frank Lampard.

"I think he needed to get out of Spurs, to be honest with you," Woodgate exclusively told Stats Perform. "I think in the Pochettino era, he was one of the best players in the Premier League. He was in the England squad regularly and sometimes it's just that manager that really believes in you and gives you that confidence to play well.

"I mean, you don't turn into a bad player overnight. Dele Alli will be good again at Everton, no doubt about that, and with the right manager it'll give him more confidence and put him on a platform to put him in the right position for him to go and do what we know he can do.

"Because at Tottenham, he was scoring goals for fun, he was running forward, he was assisting, he moved a bit like a Rolls Royce-type player. He always had time on the ball, but something hasn't gone right from the last few managers. [Jose] Mourinho, [Antonio] Conte and [Nuno Espirito] Santo. In the Pochettino era, he was absolutely outstanding."

Woodgate also weighed in on Harry Kane's failed move to Manchester City in the early weeks of the season, saying he understood the striker's stance.

Having expressed his desire to leave Spurs at the end of last season, the England captain was strongly linked with a record-breaking transfer to the Premier League champions during the transfer window.

But despite City boss Pep Guardiola publicly stating his interest in Kane, a move failed to materialise with Spurs refusing to negotiate.

Kane was heavily criticised by supporters for his position, but Woodgate believes it is only natural he would look elsewhere to get his hands on some silverware.

"I think everyone was surprised at the time," he added. "I think everyone really was because no one envisaged him coming out in the middle of the season saying that he wanted to really leave and go and move on.

"I can see his point because he wants to win the Premier League. Who wouldn't want to win the Premier League? Is he going to do that with Spurs? Not at the minute because they haven't got that calibre of player.

"They've got the right manager in but they need more players like Kane and like Son [Heung-min] to really have a go at the league. But they've got some progression to do. We've got to climb huge steps to get anywhere near the likes of Liverpool and Manchester City at the minute."

Dani Alves is the new signing to miss out on Barcelona's Europa League squad after the club confirmed his omission on Wednesday.

The Brazilian, who rejoined the Blaugrana in November, was finally registered for LaLiga duty at the start of January but will not feature for the club in their European campaign.

Alves was joined at the club by fellow new arrivals Ferran Torres, Adama Traore and Pierre-Emerick Aubameyang in January, but only three would be permitted to be included in the Europa League squad.

UEFA regulations prohibit any more than three new additions to European squads after the January transfer window.

As such, Barca had more new signings than free spaces, with 38-year-old Alves ultimately the one left out.

Ousmane Dembele has been included, however, despite his contract stand-off seeing tensions rise at the club over the past few weeks.

President Joan Laporta openly suggested the situation might make it "more difficult" for Dembele to feature, though he did leave that up to the discretion of head coach Xavi.

Like Alves, young forwards Ez Abde and Ferran Jutgla were left out of the selection despite breaking into the first-team squad – neither were registered with UEFA at the start of the season, nor do either qualify as a homegrown Barca player, therefore would have been competing with the new signings for spaces in the squad.

Barca face Napoli in their Europa League knockout play-off, hosting them on February 17 before going to Naples a week later.

Manchester City have announced highly rated youngster James McAtee has signed a new contract.

The 19-year-old is now tied to the club until 2026, with City securing the future of one of their most promising young players.

McAtee, a gifted attacking midfielder, made his first-team debut off the bench in City's 6-1 EFL Cup defeat of Wycombe Wanderers in September and has made another couple of appearances since.

One of those was a cameo against Everton in November, his Premier League bow.

McAtee becomes the fourth City youngster to sign a new deal this season after Finley Burns, Liam Delap and Cole Palmer.

He said: "I've been here since I was 11 and I can't thank everyone enough for everything they have done for me.

"I have worked with some brilliant coaches in the academy, who have put me in a position to be able to train and play with Pep Guardiola and the first team, which is all I've ever wanted to do.

"I've been really pleased with my progress this season and I am sure I am in the right place to keep improving, so it feels amazing to know I will be a Manchester City player for another four years."

Tanguy Ndombele has not tried to shift the blame for his underwhelming Tottenham performances as he accepts he is risking his career by returning to Lyon on loan.

Ndombele was a £55.5million (€62m) signing for Spurs in 2019 but re-joined former club Lyon on Monday in a temporary move that could become permanent for €65m.

The midfielder failed to show in England why Tottenham had invested so heavily in his services.

After creating 47 chances and laying on seven assists in his final season in Ligue 1, Ndombele played only 30 key passes and contributed five assists in two and a half years in the Premier League.

There were mitigating factors, with Ndombele signed by Mauricio Pochettino, who soon left to be replaced by Jose Mourinho. Nuno Espirito Santo and then Antonio Conte followed.

But the 25-year-old said on Wednesday: "It's not the fault of coaches if I had a little trouble at Tottenham.

"It's the right time for me [to return to Lyon]. For my adaptation, coming back here is the best. I hesitated: I went out through the front door, and coming back I'm taking a risk.

"If I had thought about [it hurting my pride], I wouldn't have come back. I saw the project in front of me, I saw that it was interesting for me, and for the club, too.

"But I don't think that's the easiest option. If there wasn't a good team, I don't think I would have taken that risk."

Lyon hope Ndombele is not the only player to return from north London this year, with out-of-contract Arsenal striker Alexandre Lacazette – who scored exactly 100 Ligue 1 goals for the club, at a rate of one every 150 minutes – a target.

He was one of several former Lyon men referenced as potential signings by Jean-Michel Aulas when presenting Ndombele to the media.

"In our context, [Lacazette] is more affordable than Benzema," Aulas said. "We have to try to see if we can do it as a free player, but we won't be alone."

Aulas also discussed outgoing transfers, with Ndombele set to replace star man Bruno Guimaraes, who departed for Newcastle United.

"Newcastle's first request for Bruno, we refused it," Aulas said. "It seemed logical to us.

"Events made us think differently then. We're happy with the deal, coming out of a difficult pandemic period for all clubs. We turned a weakness into an opportunity."

Jonathan Woodgate has backed Kylian Mbappe to "flourish" at Real Madrid and "be even bigger than he is in Paris Saint-Germain" if he makes the move, but the regeneration of Los Blancos' midfield is of greater concern to the former defender.

Mbappe is widely expected to leave PSG for Madrid on a free transfer when his contract expires at the end of the season.

The World Cup winner, who has 10 goals and nine assists in Ligue 1 this term, would boost Madrid in attack, but Carlo Ancelotti is not exactly short of firepower – his side's 47 goals the most in LaLiga and eighth-most in Europe's top five leagues.

And in striker Karim Benzema and winger Vinicius Junior, arguably Madrid's best two players occupy the positions Mbappe likes to operate in.

Benzema is 34 but has never been better, scoring 17 and assisting seven, with only Mohamed Salah (25) topping his 24 goal involvements in Europe's top-five leagues. The ever-improving Vinicius has 12 goals and five assists.

Asked by Stats Perform about Mbappe's potential transfer, Woodgate turned his focus instead to the middle of the pitch, where 32-year-old Toni Kroos (1,261) and 36-year-old Luka Modric (1,196) rank second and third for minutes played.

"[Mbappe] will be the biggest signing of the summer, if it goes through," said Woodgate, who played for Madrid between 2004 and 2007. "On a free transfer as well, it's incredible.

"He is a Galactico signing, one of the best players in the world, he'll flourish in Madrid, he'll be even bigger than he is in Paris Saint-Germain.

"But what concerns me in Madrid is with the likes of Modric, Kroos and Casemiro. That three in midfield are all getting to that stage where they're 35, 34 and then Casemiro. They need to start replacing them.

"Okay, they've got [Federico] Valverde, whatever, but that's the main area they need to start recruiting at.

"That three has been around for years and years and years. It's an incredible three in midfield, so it'll be interesting how they replace them three moving forward."

Pierre-Emerick Aubameyang has said it is "amazing" to have Xavi as a coach after completing his move to Barcelona.

Aubameyang joined the LaLiga giants after being released from his contract with Arsenal, agreeing a contract until June 2025 with an option to cut ties earlier, in June 2023. It includes a buy-out clause of €100million.

The 32-year-old fell out with previous manager, Mikel Arteta, resulting in him losing the captaincy at the Emirates Stadium and being left out of recent squads.

Speaking to the club's official social media, Aubameyang spoke of his admiration for Xavi, a Barca legend and World Cup winner, saying: "I think that's amazing to have [Xavi] as a coach. He has been a fantastic player that everyone knows, and I'm sure that as a coach he will bring us something that we will learn, definitely."

The Gabon international also spoke of his pride in making the move to the Blaugrana, explaining that his main goal is to help them get back into the Champions League.

"I am very proud [to be here], especially because my family is Spanish as well from my mother's side so I'm just really proud and happy to be here," he said.

"My main goal is to help the team and to give everything I can to bring the team back in the Champions League. I am just happy to be here and I will try to give everything."

Another January signing was La Masia graduate Adama Traore, who joined on loan from Wolves.

However, at a media conference to present the winger, it was another wide forward already at the club who stole the headlines as for the second day in a row, Barca president Joan Laporta openly criticised Ousmane Dembele for not agreeing to a January move away from Camp Nou.

The club had been hoping to ship the France international out, with Paris Saint-Germain reportedly agreeing terms with Dembele over the weekend, but a move did not materialise.

Barca are still struggling financially as the club attempts to bounce back from previous years of mismanagement, and on Tuesday at another news conference to reveal details of the forensic review into financial irregularities by the previous regime, Laporta responded to questions on Dembele, saying he could not understand why the player had not left in January.

He followed this up with more comments on Wednesday, telling reporters: "Our [contract] offer [to Dembele] expired on December 20 and after that, there was no other proposal. We saw a lack of interest in renewing and accepting our offer which was really good. We tried to fix things but there were no options available."

Dembele, who played with Aubameyang at Borussia Dortmund, is out of contract in the summer, and Laporta has said it will be up to Xavi whether he plays for the club again, while also indicating his belief that the Frenchman - who has suffered numerous injuries since arriving in Spain - has been disappointing since his big money move in 2017.

"We have a player with a contract that expires in June and the player is at the disposal of the coach, so the coach is the one who will decide whether he plays or not," he added. "But Xavi is just as surprised as all of us that Dembele has not renewed his contract.

"We invested a lot of money and we wanted to see that investment on the ground more often, but we came out a little disappointed."
