Giving up in the UEFA Cup - At the time, CL was the priority, I would have done the same.
Selling Gary Cahill - Yawn. IMO we have 3 centre-backs who are superior to him, he's an average centre-back, its that simple. We got a good price, end of story.
Not focusing enough on the cups in Years 1-3 - We had some shit draws in the FA Cup and a few freak results in the League Cup.
Heskey/4-4-2/Last season's capitulation - Our luck ran out, we were never good enough to finish top four.
Letting Mellberg go too easy - Was a fading force and released at the right time.
Carson/Harewood/Salifou/Routledge - Meh, every manager makes shit signings. Although Carson was an aberation.
