Gary James Posted July 7 Share Posted July 7 As the title says how is the Expected Goals Prevented / 90 calculated? As i was looking at a scouting report for a new GK I saw a the Expect Goals Prevent / 90 stat and thought I would compare it to my Goal Keeper I could see that my GK has an Expected Goals Prevented Goal / 90 Stat of - 1.44 Initially I assumed that this meant that my GK was letting in 1.44 goals a match more than he should be but my GK has conceded less than a goal per match. So I thought maybe he is saving 1.44 expected goals a match but I thought the minus sign does not make sense. I checked a few more GKs to try and work it out and saw that the Arsenal GK has a EGP/90 of - 3.19 buthas conceded more than a goal per match. So is his team extected to concede shed loads per match? Any help will be appreciated. o Link to post Share on other sites More sharing options...
gunner86 Posted July 8 Share Posted July 8 My understanding is it’s the cumulative xG of shots that are saved averaged over the amount of games. The lower score seemingly better, which seems counter intuitive I do agree. I think what’s helping Costa out here is penalties, as he’s conceded 0 out of 5 faced.

Gary James Posted July 8 Author Share Posted July 8 @gunner86 thanks for the reply. I would agree that I thought a lower score is better but then when I look at the league rankings it has the highest number ranked at 1. Also my gk is ranked at 1.05 goal per match expected goals saved / 90 which means he should have saved 31.5 goals in his 30 Premiere league matches which is an interesting stat considering he has only conceded 26. The penalty stats also show how many they have faced with the saves in brackets as you can see below. Link to post Share on other sites More sharing options...
GIMN Posted July 9 Share Posted July 9 It's an issue with that screen. It calculates the xGP for each competition, but in the donut charts it then adds those together. Link to post Share on other sites More sharing options...

Gotta do something at 4:55 on a Friday I guess 😂 Link to post Share on other sites More sharing options...
Gary James Posted July 9 Author Share Posted July 9 Still makes very little sense to me. My GK has only saved 1.44 Expected goals over all competitions but a worse GK that is performing worse has saved more. Link to post Share on other sites More sharing options...
