Tbf his contention was if a team built around him they'd win the title and Inter did do that and won the title. I don't think that's true with Chelsea because City and the RS are too good, but falling short of two of the 3 or 4 best club sides isn't really that bad.
He's only done the business at 1 of 3 big sides and that one was in a league where Juve finally decided to turn a bit plop.
