In 2013, Robin van Persie 'arrived at the Emirates with his Manchester United team-mates for the first time since making his £24million move last summer'. After saying hello to a few old faces, Van Persie reflexively turned to enter the Gunners changing room before being redirected. He may have been left red-faced, but all we can say is once a Gunner, always a Gunner! So wear the Arsenal F.C. Cap RD to remind yourself that you're a Gunner and shall remain one.
