The Jose Mourinho we all know and love is a fiery character. He gauges eyes, he goads referees, he leaves players out of squads to prove a point, he makes inflammatory remarks and he is partial to a suit-ruining knee-slide.
Since his second coming, Mou seems to have mellowed to the point that he is unrecognisable.
He is a man with a delicate ego, who clearly didn't enjoy playing the pantomime villain at Real Madrid. Perhaps in reaction to this, we are being treated to a unusual facade of pleasantness and professionalism. "I'm the Happy One," he told journalists at his unveiling in June.
The Portuguese manager once called Arsene Wenger a "voyeur" because he claimed the Frenchman was obsessed with his Blues side. This week, he had nothing but praise for the Arsenal coach, telling The Sun, "He’s a nice guy. I respect him a lot and I will show him my respect always."
In every recent interview, Mourinho seems to be expressing a veneer of niceties. When pressed about a potential swoop for Wayne Rooney by Sky Sports, the 50-year-old offered a John Lennon-esque sentiment of peace and love:
Be happy. Where is he happy? Where will he find more happiness to have ambition and drive him? I like him as a boy. I wish him well and hope he is happy.
Mourinho is known as a man driven by a relentless desire for success. He does not make life easy for his players. Could his new tranquil approach affect the intensity on the field?
It's possible, but it's also quite possible that he will be back to his old volatile ways by November.
