Is he right/left footed? When he plays from the right wing and drifts in as a typical inverted winger, he does it with his left foot (obviously), but after he moved into Manu's position, and started to create chances for the others centrally, he played mostly with his right - what about that wonderful half-volley pass to Buckley (or was it Nemane)?
Whenever I watched him, he seemed just so comfortable with both of his feet that it was almost shocking. See that goal against Chelsea, where he started off dribbling with his left but could easily finish it off from a right-footed shot. So I guess he prefers his left, after all, he's the new Messi... :)
Anyway, could be his huge asset in the future as well.
