Fellaini struggled at City, but stressed that the Belgian is not quite up to full fitness yet.
"I think the game passed several of our players by, and not just Marouane," Moyes said. "It would be wrong to pick just one out. I think when I took him he looked a little bit short and not as sharp as I wanted him to be.
"He found the tempo of training slightly different and because of that I thought he was a little bit behind. It is like everybody else in that he is getting to know the club as well. It wasn't just him who didn't come up to scratch."
