He hit problems at Real Madrid. He had passed the test to be their manager by knocking Barcelona (despite Inter barely having the ball), then the best team in the world, out of the Uefa Champions League and winning the competition, in the Bernabeu.
He got some criticism for the defensive way in which his Inter team played against Barca, but what else could he do? Barca had better players but Mourinho got the result. He had no temptation to be remembered like the Brazil team of 1982, a beautiful side that did not win anything.
He wants to win and that is what he does everywhere he goes. He usually does it with his teams playing attractive football, too.
I do not think he was cut out to manage Real Madrid. I know he did well – winning the league, Spanish Cup and improved them in Europe – and all at a time when Barca was the best team in the world.
But Spanish clubs are like teams in South America, it is the club presidents who are famous. In England, the club presidents do not seek publicity or have a high profile. In Spain, they like to be considered the most important person at the club.
