>>63092233Mourinho's entire schtick is based on winning. Results are the only thing that matter to him, and he'll use every trick in the book to gain an edge over the opposition and win. Including but not limited to "mind games", us vs them siege mentality, muh refs muh conspiracy and grinding, defensive football. He may act like a bit of an asshole, but he wins and that's the only thing that matters in mourinho's world.
He also idolises fergie and wants to have a legacy at a single club, of having a generation of supporters grow up knowing only one manager. Wenger has this too, despite being a worse manager than both red nose and mourinho by the W/L metric, the only thing that matters to mourinho. This is the cause of his cognitive dissonance, that maybe more things than winning matter for a manager, that acting like a knob is not okay just because your team wins football matches. This goes against his result only philosophy and he resents wenger for it.
TL;DR resentment and jealousy
