Just search 'Football streams Reddit' and you will find them.
If you need a second opinion because Google search has a habit of sometimes censoring and manipulating search results, especially when it comes to 'protecting copyright', use this Russian search engine.

You can watch almost anything online for free: NBA finals, Olympics, Grand Slam tennis, Euro, Copa, World Cup, all European league football games, WWE pay-per-view events etc.
You can watch Ass League games for free on Youtube, but that's because hardly anyone watches that crap and they aren't as jealous about enforcing copyright. There are not a lot of weirdos who watch or enjoy Ass League games. But they do exist. Imagine being a fuckwit born after 2000 who proudly declares he is a fan of 'Lion City Sailors'.
