Advice from an Arsenal fan

So I’ve been dating this massive Arsenal fan for almost a year now, and with her birthday coming up I figured I’d ask you guys for some advice.

I wanted to get her a new jersey, but since she has one for each of the past few seasons, with most of the current team on the back, I’m going for a less than conventional one. I’m thinking either the blue away Cech jersey (she mentioned wanting one during one of your games this season) or a 2003-04 home kit with any of Henry, Bergkamp, Vieira, or Ljungberg on the back.

Your probably wondering what advice I’m even looking for at this point, but the main issue comes with the size of the jersey. The best fit for her is a medium youth size, or a large youth if that’s the only option. I’ve been looking all over the internet for any of these shirts in that size, but it seems to be a difficult one to find.

Since you guys are probably much more knowledgeable about shopping for Arsenal gear, if any of you could possibly provide a link to a place where I can get one of those in her size, it'd be hugely appreciated
