What is the purpose of xG statistics?

This sort of statistics gives a lot of information about the quality of each team’s game. It gives the opportunity to:

• See the difference between real and alternative score in match and the difference between the number of dangerous moments which team make near the rivals goals and allow to make near their own goals,

• Check the real force and shape of each player or team, for example, the quality of a forward and the dangerous of their moments.

• See how the team play after the score change, for example how they attack when they lose in one goal.

• See the number and the danger of the moments which team makes near the opponents goals and allows to make near their own goals.

• See the impact of the “luck factor” in each match or during the whole season.
