I would be happy with the signing. I'm not saying whether he would be first priority or not, just that he is very suited to our style of play, attainable and relatively cheap. I'm not saying whether he should be considered as a long-term first choice central midfielder, just that I believe he would be a good signing for us.
As far as I'm concerned, we only have three central midfielders in Carrick, Fellaini and Cleverley that should have a future at the club beyond this season. With that - and with the foreseeable future in mind - I don't think it's a question of one central midfielder to go directly into the first team, but possibly two centre mids bought in the next two years or so.
Carrick is massively instrumental in how well we do, but at 32 he will no doubt become slowly phased out of the first eleven over the coming years; although I do think he has a solid two years left as a top performer. He is our only quality and reliable midfielder, but we shouldn't have to rely on him as much over the coming seasons.
Fellaini has struggled thus far at United and has quite frankly looked out of his depth even by our standards in midfield. Obviously, it is very doubtful he will continue to play at that level for much longer. Still, he doesn't seem the ideal fit for our midfield - which I always thought - and alongside Carrick, it means further immobility, defending too deep and offering no link to the forward players, be that with the tempo or passing he displays. He is very limited as a defensive midfielder.
And Cleverley is a very good squad player to have, a more befitting partner for Carrick than Fellaini, due to his mobility, energy and link-up play, but is also far too limited defensively and offensively as a first choice midfielder. I like him, but I don't think he will ever be at the level required to consistently maintain a starting berth in our midfield.
Essentially, we only have one current, reliable central midfielder who will unfortunately start to be on the wane within a few years and two squad players. We will probably be looking at a creative, flair central midfielder along with a replacement for Carrick within two years.
