Great form, but form doesn't qualify a player as great. I don't see him as a leader either, more the quiet type who just likes to play football. Melo is also a form player. Last season he was a turd and now he is an irreplaceable part of the midfield, so what happens the next time he goes into spaz mode? Marchisio on the other hand will be here in the long term, these sort of players compliment each other in a squad.
