Robert Lewandowski is reportedly upset with Bayern Munich after comments made about Borussia Dortmund star Erling Haaland.
Haaland has reportedly attracted interest from some of Europe's top clubs ahead of next season, with Real Madrid, Manchester United, Manchester City and Barcelona all said to be keen on his services.
Bayern are also seemingly interested after sporting director Hasan Salihamidzic's comments a couple of months ago.
"He's a great player, a great guy that the entire world probably wants. You have to look there, yes, otherwise we would be full amateurs, but he's a Dortmund player," the director told Bild at the time.
According to Spanish outlet Mundo Deportivo, Salihamidzic's comments about Lewandowski's Golden Boot rival has not pleased the Polish striker, who is in the final two years of his contract at the Allianz Arena.
It remains to be seen if Lewandowski will sign an extension, but the club's reported pursuit of the 2020 Golden Boy winner may push the Poland international towards the exit door.
Both Lewandowski and Haaland were among the 30 nominees for the 2021 Ballon d'Or award:
