Barcelona are reportedly becoming increasingly uncomfortable with Ousmane Dembele's position at the club.
The 24-year-old was a regular for the Catalan giants during the 2020-21 campaign, making 44 appearances in all competitions, contributing 11 goals and five assists in the process.
Dembele's deal with the Catalan giants is due to expire next June, though, meaning that, as it stands, he would be free to sign a pre-contract with a foreign club in January 2022.
The France international recently said that he was in "no rush" to sign a new contract with Barca, as he concentrates on representing his country at Euro 2020.
However, according to Mundo Deportivo, Ronald Koeman's side are fearful that the attacker has already agreed to join another club on a free transfer next summer.
The report claims that the two parties are in a 'difficult stand-off', with Dembele seemingly stalling on signing a new deal due to the terms of the agreement, which could include a pay cut.
Manchester United and Juventus are said to be keeping a close eye on developments.
