It is a shame that he left and in his situation, I'd do the same thing. Board and Tito should have literally licked his ass to stay but instead they apparently did the opposite. Loyalty is one thing but as has been mentioned prior, this club is deviating from its ethos too much recently and especially since we always used to put the youth first, spitting in his face like this almost deserves a certain type of retribution. Especially since he is continuing to be groomed by Pep, why should he have stayed?
Anyway, he looked fantastic tonight. Finally showing the maturity and domination of the ball that he displayed at the youth levels on the big stage and seems to be making the transition to world class. Not sure if we should be comparing him to Xavi just yet but he certainly seems destined to take his mantle once he retires.
Worry not tho guys, we got Rafinha

he shows everything that his brother possess with a bit more tenacity. Plus, never rule out him returning. You never know how things go in football and an epic Cesc like return saga to play alongside his brother certainly doesn't seem impossible.
