Just being realistic, we couldn't match his obviously extremely high ambitions. Or at least he was not willing or perhaps able to try to bridge that gap in the way Dortmund, Atlético and a few others have successfully done in recent years. This would have been really hard to achieve, and he obviously didn't fancy it.
For those talking about the management and ambition, our 'ambition' is always going to be limited by our finances. We could be super ambitious with lots of money, that's very easy. You might not agree with the players we sign, or the strategy, but that is always agreed upon as a group, something Conte was part of and increasingly influential with. Obviously not enough from his perspective. But on the other hand you can't stomp your feet about quality when several of the said dreaded squad players signed have your mark all over them.
