Carrick says the Belgium international has fitted in well and that his arrival has afforded David Moyes another excellent option in the squad.
"It was good to play with him. He's a real presence in there," Carrick told MUTV. "You could see tonight that he's such a dominant player and he gives us something that we haven't had and that's exactly what you want - options in the squad.
"Sometimes you want to play different ways and he gives us that option. There's no point in having similar players. He's fitted in well and settled in great. He's a top player and we want as many of those that we can get."
