About Rakitic, it isn't about him being or not Barca quality. He is definitely good enough to play for this team. Player is quality. The real question is fit. Does he fit with this team.
As of right now, I'd be willing to give the coaching staff the benefit of the doubt. If Lucho feels that for his new project and his vision for the team, Rakitic fits better than Cesc, for any number of reasons, then I'm happy to give him the benefit of the doubt, at least until I see the product on the field and am able to judge for myself.
But there is not doubt Rakitic has enough talent to play for this team.
