Barcelona have reportedly been told that they would have to come up with an offer of at least €40m (£33m) to sign Bayern Munich forward Robert Lewandowski during this summer's transfer window.
The 33-year-old's contract at Allianz Arena is due to expire next June, and there have been claims that he could leave the club this summer if an agreement over an extension cannot be reached.
Barcelona continue to be credited with an interest in the Poland international, who has scored 47 goals and registered six assists in 42 appearances at club level this season.
According to Bild, Bayern are desperate to keep hold of the striker, with club president Herbert Hainer revealing that a new round of contract talks will soon begin.
However, the report claims that should an agreement not be reached, the Bundesliga champions would be open to a sale if they received an offer in the region of €40m (£33m).
Manchester United have also been credited with an interest in Lewandowski, who has scored 32 goals in 30 Bundesliga appearances during the current season.
In total, the experienced forward has netted 341 goals and registered 71 assists in 371 appearances for Bayern since making the move from Borussia Dortmund in July 2014.
