Imo, he is still "turned off" for (too) large periods of matches.
It always feels as if he is not touching the ball for 10 minutes and then he creates a deadly chance or an awesome shot.
And then he goes into a sleeping mode for 10 minutes again.
An awesome action is a good thing, but being "turned off" for 10 minutes before that isn't a too good thing for a Barca's midfielder which needs to be involved in movement and passing all the time.
A quality player though, but for different styles of football.
