Marouane Fellaini has started to win round his doubters

The big Belgian was Moyes' only major signing during his one summer as United boss and was intended to be an impact player.

The former Everton man came to symbolise everything that was wrong with the Scot's brief stewardship at Old Trafford.

While Fellaini was disappointing at the start he's grown to become and important player for the Red Devils.

And Moyes has highlighted Fellaini's world-class attributes.

He told ESPN: "Well, bringing Marouane Fellaini was part of what I hoped he would come to United and play in different games.

"He was never someone who was going to play in all the games at United.

"He was someone that was there, his size is a problem to the opposition, it's also something which helps you, Manchester United you've seen many times now have used him a more advanced role.

David Moyes has been praising Marouane Fellaini

"I used to get criticism at Everton because we played him there, he's got brilliant chest control, taking it down with his chest, he's as good as anyone in the world actually and he's a good footballer, but he was never somebody who was going to come and play every single game.

"As you rightly said, if you look at the games that he played under Louis van Gaal and now under Jose Mourinho, he's vital.

"He's a modern day footballer, he covers a lot of ground, he's a decent passer without being a great passer, he can get you some goals.

"He helps you out in both boxes with his stature and he was something which we didn't have at Manchester United and he was a player who was brought in to add to the squad."
