Franck Ribery has revealed that he had a rocky relationship with Manchester United manager Louis van Gaal during their time together at Bayern Munich.
The winger worked with Van Gaal while the former Netherlands national coach was in charge of the Bundesliga side, winning the league and cup double during the 2009-10 campaign.
However, Ribery says that he did not feel comfortable alongside Van Gaal and had lost his trust in him.
"We had problems on a human basis. When he started, nobody knew what was going to happen," the former France international told Goal.com.
"His idea was that he did not care about names at all, you don't need stars, everybody had to prove themselves again.
"The first contact with him was already poisoned. As a professional you lose your trust. He does great things on the pitch but the coach Van Gaal was a bad man. Our relationship was crushed."
Van Gaal left Bayern in 2011.
