Oh yeah. Every now and then I see a little kid running around here in a Messi shirt and think:Yes. They'll still count cap sales as "fan purchases" though, and chances are it's things like that that go towards counting how many "fans" they have. 20m cap sales in UK? 20m Yankees fans in UK!
I bet a very large proportion of non-European Man Utd "supporters" are doing the exact same thing. Same as Barcelona.
But you know they'll grow out of it and probably don't give a flying fuck about Barcelona in reality.
