One thing I have noticed is that everyone can give good information about football and post good quality, but I can't give good information or post good about football and different sports.
For you to follow up about football you must first develop love for football, then keep watching football this including live matches. You can only know about football when you keep following currently matches and I believe there are sites you could read about them. And for goals update you can also check

That's right, honestly speaking the first step to learning about football is having passion and love for it that nurtures within overtime and as time goes on you might tend to learn alot about it, moreso you'll need to read news about sports as well to get ground knowledge about most leagues and teams you might love.
