I get the disappointment, but the "Conte out" talk, I do not understand. He's not the finished article yet, this is true, but he will get it right some day. What matters is that he's a huge part of why we are undergoing a winning cycle now, at the club. Perhaps some of us won't realize what we have until it's gone. Personally, I hope he stays for a long time and does become our "Ferguson".
The Coppa Italia aside (since it's such a small trophy), him not winning the CL in his 3rd season in charge should hardly be grounds for sacking him. Especially when he's bringing scudetti to the table. Alex Ferguson won 2 CL's in a 27 year stint at Manchested United.
