the special one is now the happy one

At his recent unveiling to a mammoth world press, chelsea returnee manager Jose Mourinho formerly known as "the special one"declared himself as "the happy one" hear him: "If I have to choose a nickname for this period, I would choose 'the Happy One'," he declared. "I am very happy.
"Time flies. It looks like it was a couple of days but it was nine years ago when I first became manager," he said after entering the room to a barrage of camera flashes.
"I have the same nature, I am the same person," the title-winning former Real Madrid and Inter Milan manager assured reporters, adding that he had the same heart and emotions.
"I would describe myself as a very happy person. It is the first time I arrive in a club where I already love the club. Before I had to build an emotional relationship and I only came to love the club a little later."
The question is this, (1) is jose happy because he is returning back to chelsea to continue from where he left off? or(2) is he returning back because the EPL is such an interesting league? or (3) is he returning back because there's too much money to be made from Abrahamovic? somebody out there should please tell me why this man has suddenly become "the happy one"
