Going to Qatar was a good business decision, and I won't begrudge him of that. But if we're talking development wise it is akin to a young player moving to the Chinese Super League or the Russian Premier League instead of La Liga.
Not really. A player's career is limited in time. Xavi doesn't have any pressure.
I've always said managers need to start somewhere where they can make their inevitable mistakes. The problem with big ex-players is that clubs and media expect them to do big things from the go.
Henry at Monaco is a good example. Strong ideas wrongly executed. His biggest flaw wasn't tactical, it was his handling of the players.
This is what Xavi is getting experience in, the mental part, the relation of coach-player and how to manage individuals.
Look, I'm not saying Xavi's path is the best, but he certainly isn't wasting time there. That and getting some extra pocket money lol.
