I think if you're view isn't "he's one of the best", then I'd ask what he has to do to become that, given that he's not even 50 and he's won everything there is to win.
Go to Sheffield Wednesday and win the CL with them within 5 years.
Should be easy, he's already won it before and being one of the best managers in the world should be able to do it again.
Right?
