The future of Benjamin Mendy at Manchester City is uncertain following an argument with Pep Guardiola.

Mendy is sidelined with a metatarsal injury and unavailable for Saturday's Premier League match against Brighton.

Guardiola has been annoyed by Mendy's behavior.

Sources have also said Guardiola was furious with Mendy on Sunday when the player reported three hours late for treatment at the training ground.

Asked about Mendy at his prematch news conference on Friday, Guardiola said: "Yes, he was late. I have spoken to him.

"They [the players] know that they have to be here on time."

Paul Pogba's agent will hold talks with Manchester United over his future in November.

Pogba has been at United since rejoining from Juventus for a then world-record fee of £89 million in 2016 and Mino Raiola wants to meet the club to establish whether they would be willing to let his client go in January or next summer. 

Raiola also wants to see whether Jose Mourinho will remain as manager of United in November.

United did not contemplate selling Pogba last summer when Barcelona made an offer of £45 million plus the players Yerry Mina and André Gomes.

England is set to sign Gareth Southgate to a four-year contract extension on improved terms through 2022.

The governing body has moved to secure Southgate on terms that would increase his basic annual pay, believed to be around £1.8 million, to nearer £3 million. 

Southgate had been relaxed about his contract situation.

Several of Manchester United's senior players are "angry and frustrated" with Jose Mourinho's man-management this season.

Sources say Mourinho's decision to strip Paul Pogba of vice-captaincy is merely the latest episode to bemuse the team.

Pogba was absent from the team as United were eliminated from the Carabao Cup by Championship outfit Derby County on Tuesday night.

A source who is close to Pogba's agent, Mino Raiola, has said they believe Mourinho has lost his greatest asset: the ability to cajole, read and relate to his players.

United's management remain supportive of Mourinho despite only a handful of players now fully behind him.

Jose Mourinho has informed Paul Pogba he will not captain Manchester United again due to their strained relationship.

The news was delivered to Pogba and the rest of the players at United's Carrington training ground on Tuesday. Pogba criticized Mourinho for a lack of attacking football in United's 1-1 draw against Wolves.

Pogba caused controversy after the opening-day win over Leicester by suggesting he would be fined if he said what he wanted about his situation at United.

Pogba was open to a move away from United this past summer.

Mario Gotze has been advised to join Liverpool to revive his career.

Gotze returned to Borussia Dortmund from Bayern Munich in 2016 and has struggled with injuries and illnesses.

"Maybe it'll do him a world of good to leave Bundesliga in the winter, move abroad where it's all a bit quieter and where he knock his career into shape again," Kevin Grosskreutz told Sky.

"Jurgen Klopp knows him well. He'd be a good fit at Liverpool."

Ander Herrera prefers to remain with Manchester United despite interest from Barcelona.

Herrera's contract with United expires this summer.

Herrera is prepared to snub other offers to stay at the club he joined from Athletic Bilbao for £30 million in 2014.

Herrera played for current Barcelona manager Ernesto Valverde at Athletic.

Zlatan Ibrahimovic admitted his future is uncertain and declined to commit to another season with the LA Galaxy.

Ibrahimovic has scored 17 goals in 22 games.

"I don't know. This I have to discuss," he said, according to the Los Angeles Times. "This is not the moment to talk about that. It's something I'll discuss with the club. What they want, what I want. So let's see."

Ibrahimovic has previously voiced frustration with the fortunes of the Galaxy, who are in the midst of a seven-game winless streak.

Rafael Benitez has conceded that his partnership with Newcastle is reaching a breaking point.

On Friday he made it clear the contract situation would not be revisited until the end of the January transfer window at the earliest. “We have to go to January and see what we do,” Benítez said. “After that it will be easier to know where we are. When I first decided to stay my view was very clear: to compete in the top 10. That is not the case now. So we have to review things. It’s obvious for everyone that we have to do things in another way.”

Benitez said last season's 10th place finish was a miracle.

“I’m really pleased here,” Benítez said. “I like the city, I like the atmosphere and the fans and everything. The potential of the club is massive.”

Sergio Aguero has signed a one-year extension with Manchester City that will keep him at the club until June 2021.

Aguero signed a five-year deal in 2014 and a one-year extension in summer 2016, and will be 33 when his contract expires.

"I am happy for this additional year," Aguero said. "My idea was being here for 10 years. I've been here for seven years [and] it's going to be 10 when the contract expires.

"This was the main reason I signed. I'm very happy because they have treated my very well since the first day I got here. I'm very happy with everything that involves the club, my teammates, the staff and the management team."
