Arsenal fans need to get the fuck over themselves. I wasn't aware that just because a player played for you he wasn't allowed to wear a jersey for another club. It's not like it was the Barca chairman giving him the shirt to wear and it's not like they gave him a mock contract to sign or something.

It's just a fucking shirt. He hasn't signed for Barca and this is the least aggressive of the players' and backroom staff's attempts to woo him to the club. Much more is being made of it than there should be.
