The likes of Jonny Evans, Chris Smalling and Phil Jones were among those to impress the manager on Wednesday night while there are options all over the field when it comes to picking an XI to face West Brom at Old Trafford. For example, with Shinji Kagawa and Nani performing in wide roles and Adnan Januzaj and Danny Welbeck coming off the bench, it is difficult to predict who will start on the wing this weekend.
"There is a squad," Moyes stated. "We used the word 'rotation' but I want to see good form. If you play, it makes the job much easier if you play well.
"Obviously, the performance against Manchester City didn't merit people thinking they were necessarily playing the next game.
"Ashley Young played in the game before against Crystal Palace and probably won us the match. He got the penalty kick and had the chance to score another goal when he went through. You could probably pick half-a-dozen players who didn't play particularly well against City but Ashley is fine and will be okay. We'll give him every chance to prove what he can do.
"Wilfried Zaha has not appeared as we've just not felt we've had the opportunity. I want Wilf to get used to what happens here. The competition is hard and it's just impossible to get all these players playing at the one time - we can only play 11 men on a Saturday.
"I think it's important Wilf gets to see the level of training and the level of the players and the quality they have got. Wilf is getting better and we are pleased about that."
