You might be able to find some streaming sites, especially in a local language, that allow you to watch for free but chances are they will be shut down eventually. I take it you have a favorite team that you support? The fact you've not mentioned it already is a bit unusual because that's what people speak about first - but watch a few different teams and decide if you like any of them.
You can watch matches easily from the bars, you do not have to subscribe to any channels because you might not find the games interesting but when you watch from the bars with other people that are interesting in the clubs that are playing that day. You can make new friends that you will be watching the games with. There are times when I always visit the nearest bars in my location specially for the games that are on for that day. It is not like I have not subscribed to sports channels but the game is fun watching it with other supporters. We get to share ideas about the games which can help in when we want to bet, even though it is not for that particular game that is playing but for future games.
