So, you know how sometimes you play soccer with your friends and just have fun without having a real team or coach? Well, that's kind of like non-FIFA international football.
FIFA is a big organization that controls soccer around the world. But some countries and teams don't want to follow all of FIFA's rules, or they're not officially recognized by FIFA. So they play independently, like making up their own games and rules.
Non-FIFA international football is when these independent teams play against each other in international games. They might not have fancy stadiums or big crowds, but they still love playing soccer and showing off their skills. It's kind of like when you have a soccer game with your friends, but on a bigger scale.
Plus, it's a great way for players from these independent teams to get more experience and showcase their talents to other teams and countries. Who knows, maybe one day they'll become part of FIFA and play in the World Cup!
