His time at Napoli absolutely destroyed any notion that he was still a top class manager like. Somehow contrived to not even qualify for the Champions League in his last season with a squad containing Callejon, Jorginho, Higuain, Mertens, Hamsik, Insigne and Koulibaly.
Just for contrast the now much-maligned Maurizio Sarri turned pretty much the same squad into title contenders in each of his 3 seasons there whilst being one of the most entertaining sides to watch in Europe.
He has been yesterday's man since Valencia. Was incredibly fortunate at Liverpool.
