I've never seen him play really, but he does look very impressive in the couple of clips I've seen of him. Good movement, and very importantly, looks pretty good technically. Having said that, he appears to be an AM, and IMO in Gerrard and Meireles, we're well covered in that department. The positions we should really be looking to upgrade are the deeper CM roles being occupied by Lucas and Spearing. There's an argument for playing Gerrard there, and there's a growing number of people who believe Gerrard is going to end up playing a deeper role once his athleticism and power begin to fade away, but I'm not convinced, that time has arrived yet. Gerrard has enough in his tank to offer a consistent threat as an AM, and that's really where we should be looking to play him - at the head of a three man midfield.
I'd really be happier if we were pursuing someone like M'vila or maybe even Scott Parker. I wouldn't be very pleased going into the 2011-12 with Lucas and Spearing as our first choice CMs, however much they have improved over the course of last season.
