"Ander Herrera can play in a holding midfield position which is an option. He has even played Wayne Rooney in that position. It doesn't make them tick like Michael Carrick does, of course, and we all recognise how good they have been with him in the side.
"You are probably looking at someone like Herrera because when you are limited and have no options you probably have to play someone who is most suited to the role.
"Marouane Fellaini has not been suited when he has played a bit deeper. He doesn't move the ball quick enough and he has been playing a lot better further up the pitch."
