The observed final result is not always an accurate reflection how well teams played, since chance can play a significant role in determining the observed final score. A shot-xG-based assessment of the match yields a more accurate measure of how well teams played. This is achieved by simulating the outcome of all shots observed in the match, each with a likelihood of conversion (shot xG) that takes into account shot location, shot type (header, etc.) and shot context (e.g. penalty, free kick, shot from a corner kick, shot from a cross, etc.). The values below represent the range of outcomes that could have been observed based on quality and number of shots taken by each team.
