I don't follow other people's strategies, but I learn from previous matches as a reference, for football from the start of the competition it is usually clear that the team we are playing will win or lose, based on the way they play.
It's not bad what you apply, but it would be good if, in order for you to have more expertise, you continued or started with a league, for example the Premier League, which is a league that has a very good level of football, it is the toughest league so far, so the strongest teams have always dominated, City, Liverpool, among others, there you can have a lot of information that can help you make your predictions, it is very good and apart from that the commentators in the middle of the game from some experts can help you, especially the stars that are essential for any game.
