Erm, he just won Serie A and the SuperCoppa. He's doing rather well without Spurz.
At Napoli and still burning out in first rounds in European competitions, still talking brick about his employers.
His ego thinks he should be managing Real/Barca/City/Bayern, jobs he won't get.
Edit: To be clear, I still think he's a good football manager, but Spurs was a reality check for him, his volatility limits his appeal and the Napoli gig was a rebuild. His peak of Juve/Chelsea is gone
