xXKonan, I completely agree.
This guy must play whenever possible. I don't think he is the answer at forward, but he has convinced me at all three midfield spots and at both fullback spots. It does not matter which is his best position, he pretty much covers the entire field regardless of where he lines up. I think he is the best athlete on the team, and maybe the most fit. He's got all the Barca player attributes.
Whether as replacement for whoever is hurt or needs rest, or as a sub for tired legs, he should get on the field almost every single game. Without ever being in the first 11, I see him being in the top 10 on the squad in minutes played for many years ahead.
