Espanyol coach Mauricio Pochettino says teams will have to cough up €30million to lure prolific Argentine striker Pablo Osvaldo away from the club.
Atletico Madrid are believed to have bid €20million for the 25-year-old as they seek a replacement for Sergio Aguero, but Espanyol are unwilling to lower their asking price.
Tottenham Hotspur, Fulham and Juventus have also been linked with the former Fiorentina man, who scored 13 league goals for Espanyol last season.
"If the player (Osvaldo) wants to go there is a buy-out clause of 30million euros and the league starts in two weeks," Pochettino said in Sport.
"The time has come to put the cards on the table. As far as I am concerned he is a player that is difficult to replace if he goes.
"It isn't good to not have things clear at this stage."
