I promise you that if you go canvas a random selection of North Americans you would be astonished at how many do not recognize "Barcelona" as anything but a city. Football is really not very popular there. Though in recent years it is slowly becoming a bit more watched.
I can assure you that Mexicans (where football is the main sport and has been for years) would, Hondurans, Panamanians, and many others. If you simply mean the USA and Canada say so. Football is the most watched sport comfortably, with the odd anomaly like the US.
