#Ederson highlighted how waiting deep is not a passive strategy!



If #DeGea had rushed out to engage this touch he would’ve turned a 38% goal probability chance into a 61% goal probability chance as MA could’ve easily rounded him or chipped him!
#Karius made 8 saves vs #MUFC, but GKing is about quality not quantity!



Gks, don’t always deal with these situations well & often panic & rush out allowing strikers to either chip it over them or curl it round themhttps://twitter.com/jhdharrison1/status/1414147466874785794
The GK xG model shown above looks at every shot faced, pass received, cross faced & through ball faced & calculates the probability of a goal occurring for & against the GK’s team before the event & after the event occurs!



When receiving the ball under pressure, both #Chelsea GKs have been below the #PremierLeague standard!



My handling model uses historic shot data to gauge how often certain shots should be expected to be caught, parried away from danger, & parried into danger in combination with a none shot xG model which assesses how likely rebounds are to be scored based on the parry location



My 1v1 model shows that engaging 1v1s at distances greater than 14yrds from goal just makes the finishes easier rather than harderhttps://twitter.com/jhdharrison1/status/1524130917723291649
#Ederson was the best distributer & his shot preventing was class but his below average shot stopping means his value is far below #Alisson’s!



My model finds that if #DeGea had engaged the 1st touch the chance would’ve been 0.64 ExG because even though the 1v1 is quite far from goal engaging in that location would make the GK very vulnerable to the chip, sidefoot finish, and being rounded.

I actually thought #DeGea’s footwork before the shot occurred was excellent & it got him into a great position to make the save but his shot stopping technique selection let him down at the last moment & meant he couldn’t make the save!
I’ve seen the save described on Twitter as both the save of the season & poor positioning followed by a slow recovery!
In comparison #Alisson of #LFC has prevented 18 opposition chances occurring by claiming crosses & #Alisson has played 90 fewer minutes!



I think #Mendy is a top GK by the way & he’s made many great saves this season but just because a GK is good doesn’t mean we should praise them regardless of how good their goalkeeping actually is!https://twitter.com/Jhdharrison1/status/1449448726167269379
What a ball this was


Obviously it was a top top penalty save but you could instantly tell by #Martinez’s reaction that he was gutted with the fact he didn’t manage to push it out wide.
Definition: A forced out of position 1v1 is a 1v1 which occurs either after a rebound, ricochet, or cross which results in a 1v1 situation where the GK could not possibly be inline with the ball as the situation starts & needs to reposition quickly to make the save



#DeGea showed you don’t need to start deep to get into such a position, he was over 12yrd out & was ready to sweep if he had to but because he made the decision to drop & react so quickly & confidently he managed to use his wonderful fast footwork to get back in time.
