Not a sports movie, per se, as those tend to focus on athletes, but a fan movie. (I wasn't aware that they were called fans in England, I had always heard the term "football supporter") Colin Firth plays a lifelong soccer fan, from his formative years. I don't know if his obsessiveness is at all common in England, but it must be enough so for people to recognize the archetype. I have not seen the American remake, which focuses on baseball, (probably because of the word "pitch" in the title) but in the States, that sort of fandom comes closer to (American) football. But it never get like this. The story is about how his fanaticism drives his entire life, overcoming love, marriage, parenthood, and all else. It's an OK film, but I find it hard to recommend.
