This guy is completely crazy. I've never seen someone doing what he did today at a press conference.
It looks pretty clear to me that he's leaving. He's really unhappy with the board and criticized it heavily today. I think that they lowered massively his salary and over-all, the way the treated him doesn't satisfy him and I fully understand it.
First, they didn't wanted to extend his contract. Then, when TAS didn't cancel the ban in late december, they decided to start the discussions. He deserves better and this board is a complete mess. Leaving after winning the treble is a good scenario for him. He has nothing more to prove and to win. He'll probably leave for a club in Manchester or Milano, and then come back in his local club in Brazil, Bahia.
