As most a fan of college football in America, I am not familiar with Association football.
Same here, I never knew association football was known as soccer as well, with 11 players on the field.
What countries are associated with this "association football" league?
The Laws of soccer were originally made back in 1863 in England, but now soccer is enjoyed by the whole world. 
I saw a major increase in the popularity of soccer in the United States in the late 1980s.
Yes, soccer has grown so much in the US, over 24.4 million people play soccer in the US now! 
That statistic surprises me as I had no idea the sport was so popular here in America.
It really started to pick up when the United States hosted the 1994 FIFA World Cup. Nowadays FIFA soccer video game is very popular as well.
I had a good friend from Norway who loved to play video soccer as well as playing on the field.
That's cool! The latest versions of FIFA soccer video games include exclusively-licensed leagues and teams from all over the globe, makes it extra exciting to play.
