Dimitar Berbatov was outstanding in the 3-0 Carling Cup victory and another goal from Michael Owen made it three in two outings in the competition this term for the England international.
Tom Cleverley and Nemanja Vidic were able to get some more minutes under their belts following injury and the manager felt the players enjoyed the experience at the EBB Stadium.
"They always give me nudges - it's difficult picking the team as we've a fantastic squad with so many good players," said Sir Alex afterwards. "They needed games tonight, they've not had many first-team chances because the consistency of the side means I've not needed to make many changes.
"If you look at that tonight, we had 11 fresh players from Sunday and that tells you how strong the squad is. Because it's so strong, the young lads couldn't get into the team. Paul Pogba, Ravel Morrison and Larnell Cole... I'd like to have played them all but the ones who really needed a game had to play.
"Any time Owen plays, he scores. You can't ignore that - he's a fantastic professional with a fantastic ratio of goals per games. He's just got that knack and is an amazing player. Berbatov had a fantastic game tonight and scored a tremendous goal, it was a marvellous piece of football and Dimitar slotted it home.
"But they've all done well - Antonio Valencia and Cleverley's back and that's a good thing for us because he's an outstanding footballer and it's his first game for a while - since the Bolton match.
