Summing up the xG values of a team's chances during a game is problematic. In this text, I try to show some counter-intuitive insights about "expected scorelines" by looking at the underlying probability distributions over the number of goals.
Voronoi diagrams are an interesting approach to visualize and analyse constellations of players on the pitch. In this article we want to observe what happens when we add information about velocities to the naive version which works with pure positional data.
