My 1st @goalkeeper_com piece:

How many goals were the big 6 GKs worth vs the avg #PL GK?

#Alisson was worth ~19 goals! What more does a GK have to do to get #POTY!

#DeGea was the best shot stopper but his weak shot prevention & distribution meant he was only worth ~3 goals!
#Ederson was the best distributer & his shot preventing was class but his below average shot stopping means his value is far below #Alisson’s!

#Ramsdale’s performances at the end of the season were average but his incredible start means he ended the year with great numbers!
#Mendy was in 2nd place for goal value throughout the year but a poor final few games caused him to drop off, still he was worth ~6 goals to #Chelsea!

#Lloris has gone under the radar this year & while his distribution was pretty weak his shot stopping & sweeping was class!
#Alisson was by far the GK of the year

My model finds he’s been worth ~19 goals to #LFC vs if they had an average #PremierLeague GK!

Not only is his 1v1 stopping off the chart he’s performing above the expected level for an average #PL GK in every single aspect of goalkeeping!
#DeGea has a profile unlike any of the other big 6 GKs, while he is an awesome shot stopper who saved #MUFC ~10 goals more than if they had an avg #PremierLeague GK, his weak shot preventing & distribution means #MUFC concede far more chances than they would with an avg #PL GK!
#Ramsdale’s season was like #Arsenal’s very up & down but in the end pretty solid!

In the 1st half of the season his shot stopping was +9, while in the 2nd half his shot stopping was -3!

#AFC will be hoping that next year he will be far more consistent!
#Lloris was one of the unsung heroes of the season

The #THFC stopper was consistently a solid shot stopper & this season, while his distribution was weak, his sweeping was excellent, he frequently stopped big chances occurring due to his ridiculous speed off the line!
#Ederson is a classic example of how GKing has evolved!

His sweeping & distribution is excellent & facilitates the way #MCFC play however this year his substandard shot stopping in combination with #MCFC’s great defence means that his overall worth to #MCFC was just ~4 goals!
#Mendy is a very well rounded GK, his only consistent weaknesses are 1v1 stopping & penalty stopping, in all other areas he is good.

He started off the season in incredible form but by conceding a few weak goals in the final weeks he “only” ended up being worth ~6 goals to #CFC!
A full breakdown of each of the big 6 GKs in all aspects of GKing will be coming out over the summer!

Has #Ederson turned a corner regarding his issues with long range 1v1s?

Yesterday he positioned himself perfectly inside his 6yrd box during this long range 1v1 thus allowing his defender to pressure the ball while maximising the finish difficulty for the striker!

#SOUMCI #MCFC





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

As GKs should only wait deep until the CF gets close enough that the GK will not have enough reaction time to make a save, which is what #Ederson did as he rushed & smothered once the CF was within 14yrd of goal!
#Ederson has had huge problems with 1v1 situations like these in the past as he has rushed out too soon & found himself at the PK spot (rather than the 6yrd box) which gifts the opposition CF simpler finishes like chips & sidefoots while also not allowing his CBs to get back!

#DeGea showing how to deal with a long range 1v1!

He initially stays deep & therefore doesn’t gift an easy chip/sidefoot finish by maximising his reaction time!

But once #Antonio takes the additional touch #DDG rushes out quickly & forms the block & snuffs out the shot!

#MUFC
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!

By waiting he dictated the 1v1 to MA & made him make a decision, MA chose to take another touch…
This is when #DeGea really nailed it!

Rather than continuing to stay deep #DeGea realised that now MA was close enough that his reaction time may not be enough to save the shot so he rushed & formed the premeditated block barrier reducing the goal probability to 34%!

Despite #NUFC’s loss to #MUFC #Karius showed that he is more than capable of playing at the top level!

Our model at #GKxG found his shot stopping was worth 0.22 goals more to #Newcastle than if they had an average #PremierLeague GK in goal

Full article👇 goalkeeper.com/news-and-media… Image
#Karius made 8 saves vs #MUFC, but GKing is about quality not quantity!

5 of the saves had xSave>99% thus #PremierLeague GKs save them every time!

The 2 interesting & difficult saves were the 1v1 vs #Bruno & #Weghorst’s long range shot! Which beat #PL GKs 41% & 29% of the time! Image
It was these saves whose difficulty outweighed the 2 goals #Karius conceded meaning #Karius saved an above expected amount of shots in the #LeagueCupFinal

#Karius could do nothing with the #Casemiro goal (xSave probability<5%) but the #Rashford goal was a little more interesting Image

#DeGea continues to be one of the best GKs vs long range 1v1s!

When #Anthony gets in #DeGea doesn’t rush out & gift an easy finish but holds deep & let’s his def recover & pressure the ball!

DDGs top decision making turned a 37% goal probability situation into a 16% one!

#MUFC
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 them

Staying calm & letting your defenders pressure the ball & only rushing out once the striker is closer to goal is a vital skill to master
For those people saying it was a easy save:

#DeGea made the save look easy & made the save far easier for himself due to his top class decision to hold deep & then use his top hand. This made a difficult situation comfortable!

Great decision making makes hard saves easy!

The #PremierLeague is back!

How has your team’s GK performed?

#Pickford’s class shot stopping & distribution puts him top 🏴󠁧󠁢󠁥󠁮󠁧󠁿

#Pope, #Henderson, & #Leno have had great starts at their new clubs🧤

Big mistakes have cost #DeGea & #Ramsdale 😱

#Ward has struggled in all areas 😞
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!

Thus it measures & evaluates every action a GKs makes!
This allows all GKs to be given a single number measured in goals called

“Total Value in Goals”

Which describes the GK’s value to their side vs having a league average GK & takes into account everything they do meaning GKs of vastly different styles can be fairly compared!

Will #Potter make #Kepa his number 1?

Most accept #Mendy is the superior shot stopper & shot preventer so the argument is about distributing

We @goalkeeper_com find in recent games #Mendy has been the better passer while both GKs have been equally error prone on the ball!

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

#Mendy has cost #CFC 0.52 xG more than the avg #PL GK would be expected to if they received the ball in the same situations (this is heavily influenced by his mistake vs Leeds) Image
Similarly #Kepa has cost #CFC 0.59 xG more than the avg #PL GK would be expected to if they received the ball in the same situations as he did in his last 15 #PremierLeague games, #Kepa’s numbers here are heavily influenced by his mistake vs #Liverpool which #Mane capitalised on! Image
