Despite his missed chance (which wasn't easy), I don't think he played badly. Padoin, Marchisio, Vucinic, Bonucci had bad games. Giaccherini is a solid player in my view....a better Pepe if you like in my view.
But I do agree. Elia is technically gifted but perhaps not as hard working. But against teams like Chievo, you need technical players and not hard working ones.
