Well, this is a bit odd.
Football fans can, of course, get whatever name they want on the back of their shirts within reason. But getting the name of someone who plays for someone else? Yeah, that's a bit weird.
We're off to the Emirates and Saturday's clash between Arsenal and Bournemouth in the Premier League, which the Gunners won 3-0 thanks to a brace from Danny Welbeck and a goal from Alexandre Lacazette.
One man who wasn't on that scoresheet, you'll notice, was Philippe Coutinho .
The Brazilian might be on the naughty step at Liverpool after he failed to sulk his way into a move to Barcelona, but one place he definitely isn't right now is at Arsenal.
But try telling this fan that.
The supporters' shirt was snapped in the stands at the Emirates, and while it is entirely possible that Coutinho could be his name too, it still looks more than a little odd, doesn't it?
Next week, a Liverpool shirt with Alexis Sanchez's name on the back.
