Basically the footballer is the kid in school who plays football non-stop, wears his full uniform everywhere he goes (cleats included), but is for the most part a nice kid, gets along with everybody and is actually very intelligent once you get to know him. And yes, if he does have to wear other clothing it will be some basketball shorts, a t-shirt and some $100+ Nike Shox that he bought five years ago when he was still only wearing a size 15.
"He's trackin' mud all over our haulways with those dirty football cleats! Are those even allowed here?"
"It's ok, he's cool. He's a footballer."
