He has been faithful one more year, even though he has been thinking about leaving the team since last summer. This last year has not been the best for the player due to the little playing time he has had in Barça and the disaster he suffered with the Spanish National Team in the last World Cup.
For long he has been one of the best, but he admits that lately he hasn't been up to the level required for the club. He has always been a faithful player, with a lot of moral authority within the locker room which saw him grow.
He is leaving to Qatar to improve the level of football of that country and extend his amazing carreer a bit more. With his experience, inteligence and play style, he will do an incredible job, like he did in Barça.
As far as we are concerned, we can only thank him and wish him all the luck in the world.
