Funny, I recollect his equalizer against Milan coming a bit later than that? Or his assist when we beat Lazio away? Crucial goals against Udinese and Viola when we needed it the most? Assists against Inter away when Marchisio and Vucinic scored? How about even last season, when he popped up out of nowhere against Cagliari to bring home the crucial points or when he settled Inter-Juve, or scored an important winner against Chievo?
Yes, Quag also scored against some of those teams, Chievo and Inter for instance, and I agree that his Chelsea goal was his finest moment, but it's not like Matri didn't contribute in the CL either.
These are just some examples.
Last season, fine, we got the most we could out of Quag, but it's definitely time to sell. Let's just cash in while we can.
