The thing about De Jong is that they expected Xavi or Pirlo, and he's more of a great progresser with the ball. Anti-tikitaka player who dribbles from deeper positions. He needed to wait a bit for Barca to change before he got his dues.
It annoys me to no end that Flick found a way to use him properly. He's a player I enjoy watching and I don't like to watch Barcelona so I was really hoping he'd be pushing for a move somewhere else.
