I can see where you're coming from and for United specifically I'm not sure how it would work out. Think he'd be great at Arsenal for example, putting him where Ramsey is now, or as the attacking midfielder but they don't need him considering their options at the moment. Since we always use a midfield 2, there are very few midfielders out there who I feel would fit us perfectly and look great next to Carrick. And by few, I mean like a handful in the world (Schweinsteiger, Toure, Gundogan, Vidal.. that's probably it). Most of the others are either too offensive minded, too lightweight (like Pjanic perhaps) or too defensive to go next to Carrick. That's why I think we should scrap that formation altogether, but we can't while we have RVP and Rooney both here. As it is, we have very slim pickings to choose from for who will be a perfect fit in midfield.
