Valdes is an experienced number one and played such a role for Barcelona during one of their greatest spells as a club over the past decade.
Despite that, Valdes was often one of the forgotten heroes at the Nou Camp due to the brilliance of players like Lionel Messi and Andres Iniesta.
But the talent Valdes has wasn’t lost on Van Gaal after confirming the signing on Thursday night and the man who gave the Spaniard his debut at Barcelona believes he will challenge de Gea.
“I cannot discuss that with you. I discuss that with David, with Victor – it shall be like that,” said Van Gaal when asked about competition between United’s goalkeepers.
“Nobody is happy to be no.2 and he has to have ambition to beat David de Gea, but it shall be very hard for him.”
De Gea himself has been in superb form this season and has let in just six goals in the club’s last ten games in an unbeaten run that stretches back to November.
In several games, de Gea has been the unsung hero and supporters will hope the Spain international is at the club for many years despite rumours of his impending departure.
