Oh that's nice..but in the real world all the footballers care about is: playing at the highest level while winning trophies and money. That's why Cesc came at Arsenal in the first place(and I don't think that you blamed him at the time) and that's why he would go to Chelsea.
And to be able to perform at their highest level. Cesc came to Barca to be in the first 11, which did not work out for him. Like YaYa, he is leaving to try to do better at a different top club. Good luck to him, thanks for the last few good years.
