As so often was the case when he graced the football pitches in Spain and the rest of Europe, leave it to former Barcelona midfield maestro Xavi Hernández to hit the nail on the head about José Mourinho:
"He was the assistant coach, someone who understood the philosophy of Barça and who shared many of the same characteristics of Van Gaal. He was very respected by the players. He trained us sometimes alone at Barça B and he was excellent. I'm surprised that he became known for another type of football, more defensive, because he wasn't like that with us."
And therein lies probably one of the most fascinating aspects of The Special One's trajectory thus far.
