Valdes, who left Barcelona last season has been training extensively with the club to regain fitness and earn himself a contract at Old Trafford.
Mexican side Queretaro ended their interest in the Spain international last night and Van Gaal grew frustrated when he was again quizzed on whether Valdes would stay at the club.
“It’s only talk from you. Not from us, not from Victor Valdes, only the media. I am not here to inform the media. You have to wait and listen and that’s it.
“OK, then he goes to Liverpool. Yeah, where you see that? You are suggesting and it is a big mistake to do that as the media. That’s why I am always angry. You are inventing stories.
“He is training here and I am giving him the possibility. We shall wait and see.”
With rumours that Anders Lindegaard will leave the club in the summer and possibly as early as January, it would be no surprise if United want to at least tie Valdes down to a short-term contract.
Lindegaard hasn’t made a single appearance under van Gaal this season and Valdes would offer good back-up to De Gea and another member of the Spanish-speaking club at Carrington.
