Xavi says Barcelona are "very optimistic" that their new signings will be registered, but they may not all be given the green light for their first match of the LaLiga season against Rayo Vallecano.

Robert Lewandowski, Raphinha, Jules Kounde, Andreas Christensen and Franck Kessie have arrived at Camp Nou since the end of last season, but there is uncertainty over whether they will be able to make their competitive debuts on Saturday.

The Catalan giants have been busy trying to raise funds in order to meet LaLiga's salary limits ahead of the season and activated a fourth economic lever on Friday.

Barca sold a further 24.5 per cent of their production company for €100million, having also agreed a hugely lucrative sponsorship deal with Spotify and sold a percentage of LaLiga broadcast rights, 

They have been able to lower their wage bill by offloading players and more could follow, with Frenkie de Jong and Pierre-Emerick Aubameyang reportedly targets for Chelsea.

Blaugrana head coach Xavi says he is prepared for the possibility that some of his new men may not be eligible to play this weekend.

He told reporters: "We are working hard and everyone at the club is very positive. Maybe not 100 per cent, but we are optimistic. We'll see. The club has signed very well, I am very excited about the players we have signed. We have time until tomorrow and now we are very optimistic."

Xavi maintained his plans for the opening match of the season have not been badly disrupted by being unsure over who will be available.

He said: "It has little influence, as at the end of the day we work on different systems, different variants. Either one or the other players, very few things change.

"We pretty much have two players for each position. We work the same, we don't have a different system with the way we play in attack. Not a lot varies and I insist that right now we are very optimistic of registering the players."

Manchester City midfielder Bernardo Silva and Chelsea defender Marcos Alonso continue to be linked with Barca, with just under three weeks before the transfer window closes.

A deal to sign Alonso is reported to have been agreed and Xavi made it clear he is eager to do further business.

"We are still planning ahead, that's a reality," the former Spain midfielder said. "We are going to see what we are going to do until August 31.

"Of course, we need to have players leave in order for others to come, but the transfer market is open until the 31st and there is work to be done for all of us. We'll see."

Xavi also revealed he wanted Nico Gonzalez to stay rather than join Valencia on loan for the season, adding: "[Nico] came to me three weeks ago. I insisted that he continue because he would have minutes. I like Nico.

"But a few days ago he came back and told me that there was a team where he would play. He has been brave and is going to Valencia.

"I hope he comes back more mature because it must be important for the future of Barca. For the midfield we have [Sergio] Busquets, [Miralem] Pjanic, Kessie, Frenkie, Sergi Roberto, and even Christensen, who can play there."

The Ligue de Football Professionnel (LFP) has made the decision to postpone Lyon's Ligue 1 trip to Lorient on Sunday owing to an unsafe pitch at the latter's home ground.

The two sides were due to play their second league match of the new season, having got their campaigns underway last weekend.

But the LFP has elected to delay the encounter after a pitch inspection at Stade du Moustoir deemed the surface to possess a risk to the welfare of both teams.

"The LFP Competitions Committee decided on Friday to postpone the match between FC Lorient and Olympique Lyonnais to a later date," read an official statement.

"The commission noted that the current state of the pitch at Stade du Moustoir did not ensure the safety of the players. As a result, the LFP Competitions Committee decided to postpone the meeting."

Reports suggest that both the ongoing heatwave and drought across Western Europe, coupled with the ground playing host to events for the Inter-Celtic Festival of Lorient contributed to the poor conditions.

Both teams kicked off their campaign with a win last weekend, as Lyon defeated Ajaccio and Lorient scored a surprise victory over Rennes.

Chelsea captain Cesar Azpilicueta has heaped praise on the club's new owners for showing "great ambition" in the transfer market.

The Blues entered the window restricted by sanctions imposed by the UK government on Roman Abramovich, which prevented any new signings from being made or new contracts being offered to players.

Such uncertainty ended with the completion of a takeover led by American Todd Boehly and Thomas Tuchel has been backed at the start of a new era.

Marc Cucurella, Raheem Sterling and Kalidou Koulibaly are among the new signings made by the London club, with Barcelona duo Pierre-Emerick Aubameyang and Frenkie de Jong potentially on their way to Stamford Bridge.

Azpilicueta signed a new deal after being a target for Barca and the defender is excited about what Chelsea could achieve with the quality of signings they have made.

"It's very important that we keep the ambition high and keep winning trophies - and we have showed that with our transfers and the new players coming in," he told Sky Sports.

"I've seen a great ambition, they [the owners] have been very transparent and honest since the first day. 

"We've seen straight away in the transfer window and it's not easy to step up after just a few months of sanctions where you can't make any movements.

"In football, the competition is really high. You have more teams who want players and it's very difficult. Sometimes you need a bit more time, but we've had a great recruitment until now. 

"They [the new owners] have shown in other sports how successful they have been and I am fully confident that we will have a successful period as a club."

While Azpilicueta would not comment specifically on any names, he did suggest he expects further new arrivals.

"We're still working on more until the last day. There's still some movement around and I'm very excited," he added.

Real Madrid duo Karim Benzema and Thibaut Courtois, alongside Manchester City playmaker Kevin De Bruyne, are the three nominees for the 2021-22 UEFA Men's Player of the Year Award.

The three are joined by bosses Carlo Ancelotti and Pep Guardiola, plus Liverpool's Jurgen Klopp, on the three-man shortlist for the UEFA Men's Coach of the Year Award.

Ahead of this week's Ballon d'Or nominations, France forward Benzema has further enshrined his frontrunner status, after firing Madrid to a continental double last term in La Liga and the UEFA Champions League.

But there is no room for any player from Liverpool, the side who Ancelotti's men vanquished in last season's final in Paris.

Five Reds stars - Mohamed Salah, Virgil van Dijk, Trent Alexander-Arnold and Fabinho, plus the departed Sadio Mane - made the 15-man longlist, but none made the final cut for the eventual nominations.

Other players included Robert Lewandowski and Luka Modric, who came fourth and fifth respectively, while Paris Saint-Germain forward Kylian Mbappe came eighth, one spot ahead of Madrid forward Vinicius Junior.

Benzema is feted for his superb efforts in helping Madrid bounce back to glory under Ancelotti, with 44 goals in 46 games across all competitions, while Courtois is recognised for his superb feats between the posts.

De Bruyne meanwhile helped City and Guardiola to another Premier League crown, while Klopp steered Liverpool to two domestic trophies, plus a second-place league finish and the Champions League final.

The winners will be announced at the ceremony for the 2022-23 Champions League group stage draw in Istanbul on August 25.

Premier League football returned with a bang last week, and the second round of matches throws up the first clash between two sides anticipated to be right in the thick of the battle for a top-four finish.

Chelsea's first home game of the season hands them a London derby against Tottenham, with both on a high following their opening victories against Everton and Southampton respectively.

On the weekend the Premier League celebrates its 30th birthday, all eyes will be on Stamford Bridge as Antonio Conte faces off against his former employers.

Both Chelsea and Spurs had busy pre-seasons, including the former being taken over by Todd Boehly and Clearlake Capital, and with both playing in the Champions League this season, will be among the favourites to secure their spots in Europe's elite competition once again.

Securing points against rivals in the battle may well be decisive come May, and Chelsea know they have the historic edge.

Spurs' Stamford Bridge struggles

In 2018, Spurs won consecutive Premier League matches against Chelsea – a rare phenomenon for the north London side, who are historically poor in their trips across the capital to Stamford Bridge.

Since losing 3-1 at Wembley in November 2018, Chelsea have returned to form in the fixture, with seven Premier League matches unbeaten against Spurs, six wins and one draw.

During that run, Chelsea have conceded just a solitary goal and not even that was scored by a Spurs player, with Antonio Rudiger netting an own goal in Chelsea's 2-1 win in February 2020.

Spurs' record at Stamford Bridge makes for even worse reading. Their 3-1 win in April 2018 is their only success in their last 37 visits to Chelsea, suffering 24 defeats and sharing the spoils on 12 occasions.

Kane's killing edge

Thierry Henry stands as the highest Premier League scorer in London derbies with 43, but Harry Kane (41) is now closing in on the former Arsenal captain.

The England skipper is a reliable threat in front of goal against opponents from the capital but has a poor run of form against Chelsea, having failed to score in any of his last five appearances against the Blues.

In the top-flight, Kane has only had longer goalless runs against Manchester City (seven games between 2017 and 2021) and Manchester United (six games between 2014 and 2016).

Kane comes into Sunday's clash seeking to open his account for the season but will have fond memories of his last London derby, where he struck twice in a convincing win over Arsenal in May.

Centurions in wait

Tottenham sit just one victory away from celebrating 100 wins in Premier League London derby matches and, if they beat Chelsea, will become the third side to reach that milestone after the Blues and Arsenal.

Securing a win at Stamford Bridge is difficult enough but Spurs are also edging towards being centurions in Premier League London derbies at the opposite end of the spectrum as they have 97 defeats – only West Ham (112) having more.

Both milestones could be reached during the course of the 2022-23 season, and Spurs will hope to tick off the former first.

Home headache

Two of Chelsea's last three home Premier League London derby matches have ended in defeat, having lost to Arsenal and Brentford in April.

In that run, Chelsea suffered as many defeats in three games as they had in their previous 17 – where they had only dropped 12 points from a possible 51.

Those losses to Arsenal and Brentford hit harder, however, with the fact that Thomas Tuchel's side conceded eight goals in total – as many as they had conceded in their previous 16 combined.

Spurs can pack a punch too, with Conte's men winning their last four Premier League matches with an aggregate scoreline of 13-1, which stands as the longest winning run within the top-flight.

Antonio Conte says Tottenham would be "foolish" to spend big in the transfer market and will use "common sense."

Spurs have made six signings during the window, landing Richarlison, Yves Bissouma, Ivan Perisic, Djed Spence, Clement Lenglet and Fraser Forster.

The London club have also been linked with Roma attacking midfielder Nicolo Zaniolo and Barcelona forward Memphis Depay, while teenage wing-back Destiny Udogie is expected to arrive form Udinese and return to the Serie A club on loan.

They are also reportedly set to trigger a £41million release clause to make centre-back Cristian Romero's loan move from Atalanta permanent.

Tottenham head coach Conte has vowed there is no chance the club will be reckless before the transfer window closes on September 1.

He said ahead of Sunday's derby at his former club Chelsea: "We improved in this way but I know I can't have everything quickly, it would be foolish to ask for a lot of players and spend a lot of money.

"We're doing the right things with common sense, not to spend the money on many players. Also, this is not the politics of the club, I understand this. We have to go in the right way, doing the right things."

Conte is pleased with the strength of his squad as Spurs look to make further strides after securing fourth place in the Premier League last season to seal a Champions League spot.

The Italian added: "I'm very happy with our squad because, compared to last season, we improved with Richy but we lost [Steven] Bergwijn. [Bryan] Gil went on loan but now he's in the squad of 20 players. I think in midfield we improved with Bissouma and with [Harry] WInks, and then with Lenglet behind.

"We signed players with common sense, to find players with the right characteristics, to help us have the quality. To have reliable players, players ready to have a good impact."

Tottenham will be without defender Lenglet and midfielder Oliver Skipp for their second Premier League game of the season due to an abductor injury and a hairline heel fracture respectively.

Pep Guardiola revealed Sergio Gomez will compete for a place in Manchester City's first team as he confirmed reports the Premier League champions are set to sign the young left-back.

City have reportedly agreed an £11million (€13m) deal to sign the 21-year-old Anderlecht player, having missed out on Marc Cucurella to Chelsea earlier this month.

Guardiola has been chasing another left-back to compete with Joao Cancelo since Oleksandr Zinchenko departed for Arsenal, with Atletico Madrid's Renan Lodi and Wolves' Rayan Ait-Nouri also touted as potential targets.

Although some have suggested Gomez represents a development project, with a loan move to Girona mooted, Guardiola is confident in his ability to contribute immediately.

"You know the club is always working on many possibilities and chances in all positions, and this one target is a young player," Guardiola said ahead of City's Premier League fixture against Bournemouth on Saturday. 

"In the [2017 Under-17] World Cup years ago, the best player was Phil Foden, and he was the second-best player in this tournament, then he played for Spain's under-21s.

"He was a young talented player from the academy in Barcelona, he went to [Borussia] Dortmund and didn't get many minutes, and the last year he played in the good hands of Vincent Kompany at Anderlecht and played really well.

"We targeted him and could bring him here."

Asked whether Gomez was one for the future, Guardiola responded: "No, for now, he's going to stay with us and will be alongside Joao, for left-back."

Full-backs have a vital role in Guardiola's team, with the ability of Cancelo to drift into the middle of the midfield seen as key.

Playing in this way, Cancelo laid on seven Premier League assists in 2021-22 – a tally only beaten by Gabriel Jesus and Kevin De Bruyne (both eight) among City players – and created 36 chances from open play.

He also topped the club's charts for passes ending in the final third (1,112 – over 300 more than second-placed Bernardo Silva's 769) .

Cancelo and Kyle Walker each impressed as City enjoyed over 75 per cent of the possession in a routine win at West Ham last Sunday, and Guardiola highlighted the way his full-backs must adapt against different opponents.

"It's not the first time I've done it; for many years, I've done it," he added.

"Last season, with a proper striker with Gabriel or Raz [Raheem Sterling] playing that, or with a false nine, we played it, too.

"And in many games, we didn't play it, and many games this season we are not going to play. It depends on the qualities of opponents, especially the shape of how they defend.

"The way we attack depends on how they defend. It's different to attack a four or five at the back, to see how the wingers behave, to defend narrow or wide – this affects your attack.

"You have to adapt. Since, I would say, at Bayern Munich, especially in the second season, I always used it many, many times."

Erling Haaland has "a lot of margin to improve" with Manchester City, according to Pep Guardiola.

The Norway international made the move from Borussia Dortmund to the Etihad Stadium ahead of the new season, as a flagship signing for both the club and the Premier League.

Despite drawing a blank in the Community Shield loss to Liverpool, the Leeds-born star responded with a brace on his league debut for the club last weekend against West Ham.

For Guardiola, however, Haaland still has plenty of scope to get better at City, suggesting he must work more to find the ball and bring himself into the thick of the action.

"In the process to score a goal, I do not like the striker just waiting for balls to come," he said ahead of Saturday's home clash with Bournemouth.

"If he wants to drop, he can do it. Erling has a lot of margin to improve. I would not make out he is done. He can be a better player and [he] has the will to do it.

"He likes to play football. I [have] never seen a player, [except] maybe [Lionel] Messi, who is a finished article. Always, you can improve.

"We will try to make him a better player, all our players have a lot of margin to be better. That is the reason why we are here, to try to help them."

Guardiola also touched on the title rivalry his side have shared with Liverpool over the past few seasons, framing their relationship as something that pushes City forward to new heights with each year.

"We were able to create this rivalry," he added. "The biggest opponent we face is Liverpool [and] it is an honour. Sport like this, individual [or] collective, you need someone to [make] you better."

Thomas Tuchel never felt Chelsea had a "huge gap" to Tottenham before seven months in which the clubs appeared to travel in opposite directions.

Chelsea won all four meetings with Spurs in all competitions last season without conceding.

Indeed, the Blues are unbeaten in seven against their London rivals in the Premier League, with Tottenham having won only one of their past 37 trips to Stamford Bridge in all competitions.

Spurs coach Antonio Conte said after a 2-0 Chelsea win in the EFL Cup semi-finals that Tuchel's men were "much stronger than us".

"This game confirmed what I thought about the difference between the teams," he added.

However, since then Tottenham have joined Chelsea in qualifying for the Champions League and enjoyed an excellent transfer window.

Having beaten Southampton 4-1 on the opening day of the season, Conte's side head into the second weekend on top of the table; in 2022, they have earned the third-most points in the division (44) behind Liverpool (52) and Manchester City (46), with Chelsea sixth in that regard (35).

Conte's January comments were put to Tuchel on Friday then, before the teams' latest meeting, and the Chelsea coach was asked to reflect on how the situation had changed.

But Tuchel argued his team had only dominated Spurs due to their commitment and performance in those matches – and he suggested Conte's analysis should be taken with a pinch of salt.

"I never felt a huge gap in preparing these matches," Tuchel said before Sunday's game at Stamford Bridge. "They are close matches, and they are a very competitive and very talented squad.

"I know very well what we invested and to what level we played to beat them four times and not concede a goal against this quality team in an emotional game in London that means for everybody so much.

"This was a huge effort and a big performance from us.

"In general, I don't believe everything Antonio Conte says in games like this, before games and after games.

"I admire him a lot and believe strongly that every team he trains competes for everything, no matter which team it is and what club it is. This is what he proves right now.

"They had maybe the opposite last seven months from us, given the situation.

"Everything was clear; they had something very clear to fight for, they put all the energy in to reach Champions League football and they reached Champions League football.

"Their targets were clear, the set-up in the club was clear, and they took advantage of this situation and had a very aggressive transfer period, a very straightforward and excellent transfer period to strengthen their squad in quality and in depth.

"That's why it's one of the toughest opponents. That's what it is always with Antonio Conte's teams."

Tuchel would not reveal his "secret" to keeping Harry Kane and Son Heung-min quiet, but he openly discussed how a heatwave in the United Kingdom might impact the match.

"It is demanding," he said. "It is more demanding – we see clearly from the data that the same training exercise in a different condition has a very different output and a very different effect on how you feel.

"It is maybe also a matter of how much you want it and how much you accept it.

"It will feel at times maybe very, very difficult and very draining. It is also a question of who has the ability, the will to play through the pain."

Arsenal manager Mikel Arteta hopes former captain Pierre-Emerick Aubameyang receives a "good reception" from Gunners fans if he returns to the Premier League from Barcelona.

Aubameyang was stripped of his captaincy last season before sealing a move to Barca, with further details of how the situation developed coming to light in Amazon's All Or Nothing documentary series.

In the latest episodes, released on Thursday, Arteta took strong action against Aubameyang after he returned late to training following a trip to Paris, setting in motion events that would lead to his departure.

The Amazon cameras also showed Arteta claimed to have record of numerous prior incidents of Aubameyang's indiscipline.

However, the Arsenal manager insisted on Friday he still has positive memories of the forward, who was the subject of much discussion as he emerges as a reported transfer target for rivals Chelsea.

"It's a long time since that happened. I cannot go back each time there is a series. I have made my comments on that," Arteta said of Aubameyang's exit.

"What has been done has to defend the club and put it in the best possible position.

"Auba is an exceptional player. He did so much for us. I hope he gets a good reception [if he comes back], because I think he deserves that."

Chelsea coach Thomas Tuchel worked with Aubameyang previously at Borussia Dortmund and said of claims of his "toxic influence" at Arsenal: "I experienced none of this.

"This has nothing to do with the situation at Arsenal, which I also will not comment about out of respect, because it's not on me to comment. I don't know what happened.

"In Dortmund, there was never an issue."
