The Spaniard, who was back-up to compatriot David de Gea at United final year, didn’t travel together with the rest from the squad to America for the club’s pre-season tour but no purpose had previously been offered for his exclusion.
Nonetheless, at a press conference in Seattle on Wednesday to present new signings Bastian Schweinsteiger, Matteo Darmian and Morgan Schneiderlin, Red Devils boss Van Gaal confirmed that Valdes was not chosen for the tour from the United states.
He mentioned the former Barcelona goalkeeper was up for sale as he had refused to follow the club’s philosophy.
“He just isn’t selected due to the fact he doesn’t stick to our philosophy and there isn’t any place for that 1 player,” Van Gaal mentioned.
“Philosophy is how you play football and how you keep your match rhythm. By way of example, he refused final year to play in the second team.
“That is one particular aspect of our philosophy… but there are plenty of other aspects in the philosophy of how you need to play like a goalkeeper at Manchester United.
“When you aren’t willing to comply with the principles of your philosophy, then there is only one way and which is out.
“It can be a huge disappointment. We believed that he would follow our philosophy. It is a pity mainly because we’ve got offered him the opportunity to rehabilitate, gave him a contract and then he is fit to play.
“If you usually do not play within the initial team, our philosophy would be to play inside the second team and he did not do that.”
Valdes later tweeted what appeared to be a response questioning Van Gaal’s comments.
The Spaniard wrote “…..? #respect”, as well as four pictures.
3 of the images referenced U21 matches he played for United against Liverpool, Chelsea and Tottenham last season, whilst the fourth was a photo of him alongside U21 team-mates within the dressing area.
