I've heard of Rugby Sevens, but this is the first time I've heard of Football Sixes.
I played a bit of Rugby and have always found it more exciting to watch than Football because in Football, there's a lot of waiting and passing around which is really boring to watch.
But 7-a-side Rugby (Rugby 7s) is even more exciting to watch when compared to the normal 15-a-side Rugby. It's almost comparable to Basketball with a lot of fast-paced, action-packed and intense excitement.
Although I've have not watched this Football 6s, I am quite sure that it would be as exciting to watch as Rugby 7s.
It's also nice to know that Liverpool won.
