I don't know why you're asking about apps & games. If you want to learn about sports you've got the net on your phone & home comp to learn about which ever sports you're interested in. Football site's are popular they're easy to find.
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. What medium can I follow to get good information about football matches? If anyone can help me with this, it will be great for me because I am very interested in knowing about sports but I don't have a clear idea about how to know. Also, is there any good app from where I can watch live football games and unique popular games and share good information?
