Like, is post-shot xG enough?
Since it was introduced in 2017-18 season, would it be enough to rank all top 5 European leagues goalkeepers? Or what?
Since clean-sheets and save percentages equally depend on the overall defensive performance of the team
Thank you,
Post-shot xG difference is amazing tool at indicating goalkeepers that are good on average in savings shots and to observe so called “hot goalie” effect we also observe in hockey. In football it may concern just one game, tournament or whole season (ter Stegen was probably the second most important player in 2015 Barca run).
For other stuff you need eye test.
