Did you expect someone else?
You all know about Xavi's passing, playmaking and assisting ability. But what you might not know, and what makes him the best in the world, is that he's the player that runs the most on Barça.
Not Dani Alves, not Busquets, not Pedrito. Xavi is the man that is the brains, lungs, and that simply personifies what Barça is today.
Sadly he'll never ever be considered the Top Player in the World or win a Ballon d'Or because he doesn't score many goals and just isn't that flashy.
He's 31 and has one, maybe two years ahead of him. If he starts to see the bench he might leave soon like Guardiola did once upon a time.
€70 million would make Barça think about it for a player that old, but the truth might be that unless Xavi wants to leave, he'll be there for as long as he wants to.
