Discover the secrets of xG, xA, and shot quality to become a more informed football fan

Football, or soccer, is a sport that has been dominated by traditional statistics such as goals scored, assists, and shots on target. However, with the advent of advanced metrics, fans and analysts can now gain a deeper understanding of the game.

One such metric is expected goals (xG), which measures the quality of chances created by a team or player.
