In terms of winning titles and CL I agree however in terms of competing for the top 4 and domestic trophies / Europa Leagues he's still one of the best managers in the game imo.
We have a weird obsession in the english media/game to label any manager over a certain age as past it yet hardly any young hipster manager (including Poch) has won anything near what the likes of Jose and Wenger have even in their "decline" years.
Wenger was hammered by the media in his final years but his Arsenal side still won trophies and played alot better than the current rabble under Emery.
Jose simply doesnt have a track record of making bad sides good.
Hes lost some of what made him the best also.
Hes still 1 of the best managers in the world, but I personally think him being here would be a quite terrible thing for this club.
Managers have to fit clubs and Everton and Jose is a terrible fit.
It would be an utter crapshow.
