It'd be a good move if and only if we bring in another midfielder to protect Carrick. He's got a good eye for a pass, and he can tackle. But he's no Keane, his style isn't the same. At Tottenham he does well because Davids covers for him, so he doesn't have to do as much of the dirty work.
He'd be great as a deep-lying playmaker though, given his vision and passing ability.
