He is the back bone of Barca , for me he the most important player in the squad after Messi. He is one of the most underrated players of all time. He runs all over the ground , his passes are so accurate and tackles are so deadly .
But for being famous , featured by media you need to score many goals but his job is even harder than that . He controlls whole Barca midfield . He doesn't blonde his hair , sponsor many brands so he doesn't get much attention but he is one of the best.
