It must have been hard for him this year to no longer be top choice at this position. He handled it with good graces.
It is not likely he would be Barca head coach in only two years. It might be longer than that before he rejoins the team at all, and even a decade before he could be seriously considered to take over the team.
It's hard for me to absorb that there will be no Xavi on this team next year, even though the writing has been on the wall for a while. It almost seems like the team should change its name or its colors now.
