Van der Sar said: “You need 11 players on the pitch and ideally you want your best players. Wayne is one of the best but if he cannot play then we have others who can come in and get a chance - we are not only about Wayne Rooney.
“We have a big squad so if it’s not working out for someone then we have other good players who can come in. Kiko did well in Spain to see the space Hernandez had created for himself and Javier then took his shot fast to score.”
Van der Sar knows it’s hard for youngsters to make the breakthrough at United but added: “This is a club where if you get a chance you have to take it."
