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. 5v6m6i
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:
Paulo Gazzaniga of Tottenham Hotspur
Premier League: Week 15
Moenchengladbach’s goalkeeper Yann Sommer
Bundesliga: Week 14
Villareal’s goalkeeper Sergio Asenjo
La Liga: Week 15
PSG’s goalkeeper Keylor Navas
Ligue 1: Week 16
Robin Olsen of Cagliari Calcio
Serie A: Week 15
