To celebrate his 750th Barcelona appearance, someone sat him down with an iPad and replayed some of his goals for the club.
I've had a look on Wikipedia and it says there he's scored 84 in total, just about enough to be impressed by his memory I reckon. If he'd only got 10 or something I probably wouldn't have bothered posting this.
Won't be too many more though. He's just announced that he'll be leaving for Qatari club Al Sadd at the end of this season.
