Do you find Jose Mourinho a bigheaded manager?

Considering when he managed Inter he got his players playing with dirty tactics against Barcelona two goals were offside but allowed and Barca had a goal disallowed which would've been a equalizer and it's a coincidence he doesn't mention that now. I thought Barca would knock him back down to earth seeing as his mindgames towards Guardiola wasn't working and, he seems very dodgy after being seen taking that ref for a meal before the game anyways anyone agree with me?
