Mourinho is still the Ultimate Underdog manager. If there is a manager that I woulf trust to take a lower ranked team in a disadvantage, all odds against them against a much bigger team, it would be Mourinho and then probably Simeone. Jose's style and tactics would suit perfectly to a tee because there wouldn't be any pressure to adhere to a particular tactic, style or method and the only thing essential would be providing the win. Look at his Porto and Chelsea sides. But at the very top tier clubs like Manchester United, Real Madrid, Barcelona, Bayern, Juventus and now the likes of PSG, City etc. There is a requirement of not only churning out results, but also the results should be there alongwith good attacking play and tactics, winning mentality, aesthetically pleasing style of play which suits the image of the club. It also helps satisfy the fans and attract the best of the players.This is where Mourinho fails I think. And now, with the evolution of tactics and inflow of huge money in the EPL, he has become quite predictable and easier to defeat.
