He knew fine well every last gesture, bit of body language and expression would be read into, to look for signs of a goodbye.
And, he made a proper goodbye of it, didn't seem to care, didnt stick with the team, went off on his own and let himself get emotional.
So I see that as mind made up and pretty serious, and I now believe the rumours, whoever happens to have leaked them. I also partly respect that he did that, didn't try be coy or guarded. Yet to be seen if anything materialises or how quickly. I still think, if we are interested the gap will be way too big to get a deal done.
