Now. I'll caveat this by confessing that I've never seen him play. However he is, and has been an attacking, creative midfielder of high repute for some time. Barca took him from Dinamo at an early age. He's diminutive and plays in a similar manner to Modric by all accounts.
Think Modric when he came to Spurs, playing off a forward - rather than the more developed Modric playing from a deeper role.
I'm very, very keen to see him come to Goodison. He's full of potential though certainly would fall into the "can he do it on a cold Tuesday night at Stoke" bracket.
