Van Gaal brought the former Barcelona player to Man United in January but Valdes is yet to make a first-team appearance.
Del Bosque is still keeping an eye on Valdes’ progress but insists he must play more if he wants to get back in the Spain squad.
Speaking about Valdes, Del Bosque said: ”Yes. I know that he is training. I try to look whether he is in the United’s bench and I can see that he is currently a substitute.
“I wish him to play because he has always had a sensational behaviour with Spain. I would like him to enjoy his job [rather than being on the bench] because at his age [33-years-old] it is important to be active.”
Valdes is a top-class keeper and would walk into almost every team in Europe but unfortunately for him De Gea has been on a whole different level this season.
Nevertheless, Valdes is a fantastic plan B should the worst happen and De Gea suffers an injury. It is the kind of depth that United will need if they qualify for the Champions League this term.
