Neither had Conte or Jose and they both fudging failed mate.
The piece here you are missing is when everything wasn't handed to them on a plate, neither of those "great" managers could cut it, when they had to compete on anything like even footing or heaven forbid, at a disadvantage they were clueless, threw everyone under the bus, created a totally toxic atmosphere and generally got schooled by managers who we will forget they ever even existed in 5 years.
There are no "great managers", there are managers that are a "great fit", Pep would fail miserably at Spurs, Conte/Jose were bad fits.
Ange has a long way to go, but not tinkling on the club/players, actually playing sensible formations, actually looking at what players are doing on the training ground and rewarding them, crazily enough seems a huge step up from the brick of the last 3 years.
