United great Paul Scholes described their display against Liverpool as a shambles to heap even more pressure on Van Gaal.
Asked about his future Van Gaal said: “I don’t want to discuss that with you. You are not part of the people who determine it.”
Van Gaal has been quick to remind his many critics that United remain in three competitions and can still win something this season.
They face West Ham in the FA cup quarter-finals tomorrow and host Liverpool in the second leg on Thursday.
He added: “The standard is not good enough when you think you have to be champions, or win the Europa League and FA Cup.
“It of course gives much more pressure. I don’t want to hide behind the injuries.
“But we are still in three competitions, we can fight for a lot. Still we have the chance to win something. You have to believe in that. A lot of my colleagues are not in three competitions any more.”
