Bayern are ridiculous. No ideas, no system, no nothing.
Lahm criticized the Robben transfer, he said Robben is a great player but we can't just buy someone because he's a good player. He needs to fit in our team and in our system, our formation. And he's right with that.
Van Gaals behavior with some players is a bit questionable, for example Mario Gomez. He scored but was benched, and Van Gaal ignores him and says to the media oh it's not my fault, why is he here? I didn't buy him.
