Barcelona have set an asking price of €100 million (£88.7m) for clubs hoping to sign their forward, Ousmane Dembele.
Liverpool are among top European clubs looking to sign the player next summer.
The 21-year-old French star’s future at Barcelona is in major doubt as the club are weighing up the prospect of selling the winger next summer.
Dembele has the attitude of regularly turning up late for training and has been dropped from the matchday squad on several occasions by manager Ernesto Valverde.
Sport reports that Barcelona have issued Dembele with an ultimatum by telling him to improve his attitude.
The player has been told that should he fail to improve, he would be sold at the end of the season.
Barca paid an initial £96.8m on signing Dembele from Borussia Dortmund.
Premier League side, Liverpool and Arsenal have both been heavily linked with a move for the forward.
