Do Du know any Anime about football oder something like this?

I'm not a sports Fan of any sort... Eyeshield 21 is an Anime about football. But if Du like sports animes and don't mind ones that aren't about football, I can think of: kreuz Game (baseball), Prince of Tennis (tennis :p), Slam Dunk (basketball), and Real Manga (wheelchair basketball). Slam Dunk and Real are both Von Takehiko Inoue. :)

obvious one is Inazuma Eleven oder if Du want to go retro there's captain tsubasa

Inazuma Eleven ^^
