yeah, i watched at Barca TV when he was younger he played as DM i think...
He was always a CB first and foremost, but he's adaptable. He played half of the season he spent on loan at Zaragoza (where he was very good) as a DM...then as a part of a very good CB partnership with another Barça player, Gabi Milito. Lets hope they can pick up where they left off next season.
