Manchester United striker Wayne Rooney has hailed the squad's depth after their 4-0 FA Cup drubbing of Arsenal.

Rooney said: "Last season we had to play all the players in every game.

"But this season you see Scholesy getting a rest - and at the end of the season that (resting players) could be very crucial.

"Arsenal could not cope with us as we were making runs all over the pitch. We got our tactics spot on."
