Congrats on your film Fred!
Some members won't have much idea of what your kind of football is, since they live in countries where some other kind of football is better known - like Australian Rules or Rugby League in Oz,  Rugby in New Zealand, or that weird thing they play in the US with helmets and lots of padding.  So to be fair, you should probably make the topic ANY kind of football. 
I know Soccer has a round ball, that's about all I know about it....  oh yeah, and soccer hooligans... and there's a world cup isn't there....
Well, it should be a great opportunity for some classic "bouncing ball" animation!
