To create the league rankings, we take all shots faced by all goalkeepers to date in their league. We learn a set of embeddings that captures the different skillsets of a goalkeeper, which we can then swap in order to simulate their performance.
This gives us the total number of goals each goalkeeper would have been expected to concede (xG) if they faced every shot. To make this more interpretable, we first standardise the xG’s from a season total to per game, and then take this from the league average.
This final value is the number of xG’s a goalkeeper would have either prevented or conceded compared to the league average. So without further ado, here are Stats Perform’s goalkeeper rankings for Dec. 10:
