Man Utd senior players surprised Fergie gave Da Silva twins wing start

Edwin van der Sar hailed the impact of the Da Silva twins in their FA Cup victory over Arsenal.

Van der Sar admits the selection of Fabio and Rafael even surprised senior United players.

"It was a team we had never even trained with, let alone played," Van der Sar said. "I was chatting to Patrice (Evra) in the car going to Old Trafford the day before the game about what the team was going to be.

"We came up with Fabio on the left. We never guessed Rafael would be on the right wing.

"They bring a lot of energy and enthusiasm to the team. We have seen them at the back, but they don't stay there for long because they are always going forward."
