Franck Ribery reveals rocky relationship with Man Utd boss Louis van Gaal

The winger worked under Van Gaal when he steered the Bundesliga giants to a league and cup double during the 2009/10 campaign.

But Ribery claims Van Gaal made him feel uncomfortable and that their relationship spiralled out of control after their first meeting.

"We had problems on a human basis. When he started, nobody knew what was going to happen," Ribery told football website 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."
