He's leaving because he can't be a starter for Barcelona anymore. I would say that he has had a chat with Mourinho and he isn't coming to sit on Chelsea's bench.
Why people blame the board?? They are supporting the manager. If Mourinho said "Sell Hazard, buy a toaster and a fridge" then the board would buy a toaster a a fridge to be Hazard's replacement. Blaming the board is easy and unfair.
Would have played 4 matches for England, but he is spanish.He was under-21 in 2010. And he got 12 NT appearances in two years for the best national team ever. Furthermore, he was only 21-23 years old. NOT BAD.
