This is the same question club board directors/owners will be asking themselves if they have any interest in Mourinho's services, imo, he's been sacked too many times already, that could be an indication they his philosophies are prolly no longer what's expected nor what's adequate in the modern game; Mou is more of a defensive than an offensive manager, though that methodology has worked in the past and he's won quite a lot of trophies with it, but big clubs hardly want to play that way cause they have big players, thus they are expected to dominate most of the games they play, and not to sit back and wait for the counter.

A smaller club would fit Mou based on his philosophies, but then he is a big manager, and a small club isn't at his level/standards, that's the delimma, I'm pretty sure Mou would not return to the EPL for now, the French or Italian league would be a good option, but the question is which (BIG) teams will want him, I can't think of any as of the moment.
