True but ManU probably have more supporters in Scandinavia than in Britain... If you mean the whole world there are more ManU fans in places like the Far east than those that speak English.
I mean you can go to the strangest places in the world and instead of boys wearing football tops of the local teams, they'd be wearing a ManU or Juve top for instance.
Naturally I would have to say ManU :angel: Next I would say it's Real, then Juve and Liverpool. I know a lot of people haven't mentioned 'pool but they (like united) have huge support in scandinavian countries, amongst others...
