It's sad to see legends overstaying their welcome. That was one of the good things about Seinfeld - it left on a high note.
On the other hand, MJ playing for the wizards or Pablo Aimar playing in the Malaysian League is a bit sad.
In a similar vein, Jose Mourinho is a legendary coach, particularly for his exploits with Porto and Chelsea.
But even his biggest supporters have to admit he has done pretty poorly apart from those jobs and it has been a while now.
Bad at Real Madrid, terrible at Man Utd and I guess it is still early days at Tottenham but he has managed to piss the players off.
My observation is that he isn't able to click with this generation of footballers as well as he did with the previous one. It happens even in the workplace and it's probably time for him to retire.
