I've looked at the clip numerous times now and for the life of me I cannot tell if he's being serious or not with regard to leaving.
When you really think about it though, would it actually be that much of a surprise if he did head for the sunset if we pull this off...?
He would go down in history as our greatest ever manager, be loved for eternity by fans, he would have achieved his dream that he has constantly harped on about since his arrival, win a Champions League with Tottenham. He's also said numerous times how he would like to leave on a high, and not end up like Wenger where you go from hero to villain by outstaying your welcome.
As well as all that, I'm sure he's acutely aware of the major surgery that needs to be done to this team, and the relationship he has with some of those boys would make it so difficult for him I would imagine to tell some of them they're no longer wanted after just being crowned Champions of Europe...
I hope I'm completely and utterly wrong in everything I've just said, but I genuinely wouldn't be so sure what he's saying is purely sarcasm..
