Visiting the stadium

Hi guys I’m from Hong Kong and I’m gonna visit Barcelona on September is planning to watch a Barcelona home game, since Europe is kinda far away I don’t think I’ll visit there for a couple years.

So I wonder which seats are the closest to the player tunnel because I really wanna try to get my araujo jersey autographed or simply take some pictures up close cuz I feel like he’s not gonna stay here that long although I really want him to stay
Thanks in advance!!
