LONDON (AP) — England midfielder Conor Gallagher has returned to Chelsea and is training alone at the club after issues arose in completing his move to Atletico Madrid.

Atletico posted a message on social-media platform X, formerly Twitter, last Saturday with a picture of Gallagher at Wanda Metropolitano stadium, saying he was there to “finalize his transfer” for a reported 33 million pounds ($42.5 million).

However, Gallagher has had to go back to Chelsea without tying up the deal, reportedly because of the collapse of an agreement that would have seen Atletico striker Samu Omorodion move in the opposite direction.

Chelsea manager Enzo Maresca said Friday that Gallagher is back in London, “training a little bit apart” and will not be involved in the team’s opening Premier League game against Manchester City on Sunday.

“He is trying to find a solution with (the) club,” Maresca said.

“Hopefully, for Conor, this situation is going to finish where the player, the club, the manager, all the people involved are happy.”

Gallagher was Chelsea’s vice-captain last season and played for England at the recent European Championship.

After a successful loan spell at West Bromwich Albion, Conor Gallagher has returned to Chelsea and is now reportedly eyeing a move to Atletico Madrid. The 21-year-old midfielder impressed during his time at West Brom, earning praise for his performances and establishing himself as a key player for the team.

Gallagher’s return to Chelsea comes at a crucial time for the club, as they look to strengthen their squad ahead of the upcoming season. With the departure of several key players, including Eden Hazard and Willian, there is a need for new talent to step up and make an impact.

Atletico Madrid, on the other hand, are also looking to bolster their midfield options and see Gallagher as a potential target. The Spanish club has a history of signing young, talented players and developing them into top performers, making them an attractive destination for Gallagher.

Gallagher’s versatility and work rate make him a valuable asset for any team, and his potential move to Atletico Madrid could provide him with the opportunity to further develop his skills and establish himself as a top player in European football.

While nothing has been confirmed yet, it is clear that Gallagher’s future is bright and he has the potential to make a significant impact wherever he ends up. Chelsea fans will be hoping that he stays at the club and continues to impress, but if a move to Atletico Madrid does materialize, it could be an exciting new chapter in Gallagher’s career.
