Think he'd be a great addition. Him and Davis would be a good, well balanced partnership - Vaughan sitting deep, pulling the strings and Davis pushing forward.
Needs a run of games. Would have put him on instead of Healy/Diouf on Saturday, playing just off the strikers, where IMO whenever he's played there he's looked impressive!
Good vision, technique. But nothing else really going for him. He'd be a good back-up, but if he wasn't getting a start most weeks he'd kick up fuck, IMO.
