Louis van Gaal says he'll quit Manchester United if he feels the players are not behind him. Van Gaal insists he has the backing of both his players and the club's American owners ahead of a run of games that will make or break United's hopes of qualifying for the Champions League.

"When I see this chemistry between myself and my players, then I don't have any doubts.

"Of course, we have disappointing moments but we can survive and we have confidence to qualify for the Champions League.

"I remember when I went to AZ, a very minor club in Holland. In my first season we were second, in my second season we were third and in my third season we finished 11th.

"I said to my players that I would go away. But the players then came to my house to ask me to stay, and so did the board. So I said, 'Okay, I will stay.' And, in the fourth year, we were champions."

Van Gaal added: "When I think the chemistry between the players and the manager is not good enough anymore, then I go.

"It is not a question, I can go for myself also. I am in my first season here and I can still win the title, but that will probably go to Chelsea. What we have to do is continue in our process. But we have been in the top four longer than Arsenal this season. That is true."
