i don't like this account, they love to remove sources from stuff they post.
according to fbref:
- save%: perin 90,3% (1st in the league), tek 72,3% (somewhere in the middle of the list)
- psxg-ga (which is the difference between the expected goals conceded and the actual goals allowed): +5,4 (1st in the league; 2nd is falcone with +3,6, but he played 26 matches, not 4), tek is at -0,1, so he's basically performing as expected by the statistical models
- even better: psxg-ga/90, so the last stat per 90 minutes: perin +0,71 (so he saves ~0,7 expected goals per match, which was helped by the penalty he saved but still excellent), tek is at -0,01, which means he saves what the average goalie can save, nothing less, nothing more. perin's sample size of 4 matches is a bit short of course, but for context, the 2nd on this list has +0,22, an other 4 goalies are between +0,1 and +0,2, which makes perin's +0,71 probably unsustainable on the long run. some of the best from other leagues: kepa +0,47, allison +0,42, neto (our ex keeper) +0,35 (all better than the rest of serie a), spain has 2 goalies over +0,3, ter stegen +0,22, oblak +0,12, sommer +0,37, neuer +0,31, donnarumma +0,12. anyway, you get the point.
i'd love to see this without penalties though. he also made quite a progress compared to his previous seasons, he still looks sharp as fuck this year. probably our only player who's performing way above expectations this term. it's clear by both stats and subjective evaluation that we're benching the better goalkeeper.
