Speaking to Dutch newspaper De Telegraaf, Robben said: "Manchester United? That's not an option. I am staying at Bayern Munich. Period.
"And I cannot imagine that Bayern would want to sell me.
"I have only just renewed my contract and we are happy with each other. It would have been a different story had I been unhappy.
"I would have been open to a move then, because I had a great time under Van Gaal at Bayern. He has been very important for my career. However, fact is that I am very happy at my current club."
Robben will play under Van Gaal for the Netherlands at the World Cup this summer before the manager takes up his post at Manchester United, and the former Chelsea man feels he was the perfect choice to replace David Moyes.
