Barcelona are reportedly of the opinion that Ousmane Dembele's agent has offered the attacker to Premier League trio Manchester United, Chelsea and Liverpool.
The France international's contract at Camp Nou is due to expire next June, and it is believed that the two parties are struggling to come to an agreement over an extension.
A number of clubs are said to be keeping a close eye on the situation in the event that the World Cup becomes available on a free transfer next year.
According to Mundo Deportivo, Barcelona believe that Dembele's agent Moussa Sissoko is actively offering his client to Man United, Chelsea and Liverpool.
The report claims that Juventus are also firmly in the picture for the attacker, and Ronald Koeman's side could attempt to sell him in January unless he pens a new deal before the end of the year.
The 24-year-old has scored 30 times and registered 21 assists in 118 appearances for Barcelona in all competitions but is yet to feature this season as he recovers from knee surgery.
