you can. You can always find them for free, but only when the game starts since copyright and stuff. Quality is not that good, but it works awesome when your sitting in class and a good game is on.
Just google the game match and something with “stream”. What people do is host it on a streaming website so you can see their feed, live football.
There are lot of pay websites, but I don’t want to deal with that crap, usually consists of downloading and stuff. I don’t have the links here but I can probably post some links that usually have people hosting live football later.
