Bayern Munich sporting director Hasan Salihamidzic had admitted he wasn’t happy with manner Robert Lewandowski left the club.
Lewandowski who spent eight years as a Barcelona player, had to push hard for his exit from Bayern Munich.
Before his exit, the Poland international made it clear that he didn’t like the relationship between him and the club board.
Bayern bosses didn’t want Lewandowski to leave, but ended up letting the 33-year-old go for €45m.
Salihamidzic has now revealed what he didn’t like about the transfer.
“We will definitely talk to Joan Laporta about it [Lewandowski’s behaviour] the next time we see each other,” Bayern Munich sporting director Hasan Salihamidzic told Bild.
“It’s something that Bayern does not accept. I don’t understand Lewandowski. My father taught me that when you leave, you never close the door with your butt. Robert is on his way to doing just this,” he explained.
