So this left me to ask the question does statistics really work in football or it just a coincidence that it happens
Yes! statistics is the most reliable source of information that you can consider to predict the outcome of the match. It’s like technical analysis on trading because it’s the log of players contribution on the game to measure their effectiveness.
Not only on football but in all sports. There’s a lot of factor to be considered but stats alone can give you already a solid analysis that will help you to your prediction.
I won most of my sports bet by doing analysis on stats.
