Sir Alex Ferguson suggests he has a very deep squad that can see any of his players picked for an important cup final or league fixture.
He said that any player has to be ready to step up when a big game approaches and added that he will be using his entire squad for the remainder of the campaign to allow that to happen.
"I left him out of the semi-final because I couldn't risk him and Roy Keane together as they were both on yellow cards. He accepted it graciously, came on, got booked and missed the final anyway.
"What did he do? He didn't let it affect him. He went on to become one of the greatest players this club has ever had.
"The players sense it could be a big year for them.
"But at this club, in this situation, anything can happen on the run-in. Players can all of a sudden find themselves playing in a final or an important league game because that is the kind of squad I have."
