Barcelona are reportedly concerned that Ousmane Dembele will run down his contract at Camp Nou before leaving the club on a free transfer.
The 23-year-old has made 82 appearances for the Catalan giants since arriving from Borussia Dortmund in 2017 but has largely struggled to impress.
The France international was strongly linked with a move away from Ronald Koeman's side over the summer, with Manchester United thought to be interested in a deal.
The World Cup winner remained at Camp Nou, though, and has been in relatively good form during the 2020-21 campaign, contributing three goals in eight appearances in all competitions.
Dembele has still not penned a new deal with Barca, however, meaning that as it stands he would be able to discuss terms with foreign clubs over a free transfer in January 2022.
According to Sport, the La Liga giants are fearful that the attacker already has a plan to run down his contract with the club before moving on a free transfer in the summer of 2022.
Juventus are believed to be closely monitoring developments surrounding the former Rennes youngster.
