I can't speak for the rest but i'm not unconsciously bashing Mourinho.
In my opinion, Jose from a defensive perspective is the better manager and Pep is the better one offensive wise. I can understand both's view point and I think is generally boils down to what type of football you prefer watching. I prefer Jose's and Simeone's type of football and I think when executed properly, is the more effective one.
Let's not forget, they generally have rather "similar" concepts too. Is really not that different from what people put them out to be.
Pep:
He prefers to lengthen their own defensive part and congest the opponent's defensive area. His idea, imo, is to bring the play as close to the opposition's defensive area as possible and then, is up to the players to work something out.
Jose:
He prefers to lengthen his own team's final third and congest his defensive area. His idea, imo, is to lay a foundation for the players to attack. Players have to think how to attack.
