Not a good night for #Ramsdale!
The 4th goal summed it up!
-Engaged the 1v1 when it was 20yrd out & there was a CB covering making the finish far easier
-Using the smother technique rather than the spread technique making the chipped finish far more difficult to save

My 1v1 model shows that engaging 1v1s at distances greater than 14yrds from goal just makes the finishes easier rather than harder
The best GKs (like #Alisson) often wait deep & lure the striker in & then engage the ball once they know they can snuff out the shot!

My 1v1 model also finds the smother to be very vulnerable when the 1v1 is central as it often allows the GK to be rounded or chipped plus it does very little to cover the side the GK does not have their hands!
A spread wouldn’t drastically increased the Rambos save probability!

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!

Today I’ll breakdown #DeGea’s performance in the #PremierLeague using my bespoke GK models!
The headline is for the first time in 3 seasons #DeGea’s shot stopping skills are outweighing his weak shot prevention skills & thus far he has saved #MUFC ~5 additional goals!

Shot Stopping:
#DeGea’s shot stopping has been world class, my model predicts he has saved #MUFC ~5 goals more than an average #PL shot stopper would’ve thus far!
The goalmouth map highlights just how hard #DeGea has been to beat, if you don’t hit the corners you won’t score!

His Best 3 Saves (Lowest ExSave Saves Made) are below 😮:
1. 24% Save Probability vs Jesus
2. 34% Save Probability vs Almiron
3. 42% Save Probability vs Pukki
They highlight #DeGea big strength, his reflexes & ability to cover huge amounts of the goal area.

#DeGea’s ability to deal with crosses has quite rightly been criticised.
In the #PremierLeague #DeGea has only prevented 6 opposition chances occurring by claiming crosses!
My model finds this lack of activity means #MUFC concede on average an additional 0.14 ExG every game!

My model finds this lack of activity means #MUFC concede on average an additional 0.14 ExG every game!
In comparison #Alisson of #LFC has prevented 18 opposition chances occurring by claiming crosses & #Alisson has played 90 fewer minutes!
This difference in cross claiming ability corresponds to #LFC facing on average roughly 0.36 fewer ExG per game in comparison to #MUFC!

Additionally #DeGea’s sweeping numbers have also been low this season.
In the #PremierLeague #DeGea has only prevented 4 opposition chances occurring by sweeping throughballs!
My model finds this lack of activity means #MUFC concede on average an additional 0.07 ExG every game!

#Alisson’s #PremierLeague form is an absolute joke! 🔥
He’s faced 7 1v1 situations so far & saved all 7! 🤯
My model predicts an average #PL GK would’ve conceded ~4 goals from those situations by now! 👑
How long do we think he can keep the 100% record? 🤔

#LFC #LiverpoolFC
My model uses a database of #PremierLeague 1v1s to not only calculate the expected save probability of each 1v1 situation but to also predict what the optimal strategy is in each situation & how likely a GK would be to make the save for a given decision (for more see thread👇🏻).
Class from #Alisson!
Wonderful decision to wait & react rather than engaging #Pukki!
#Alisson’s improved so much vs long range 1v1s!
19/20 long range 1v1 ExSaves: 6.01
19/20 long range 1v1 Saves: 5 ❌
20/21 long range 1v1 ExSaves: 11.46
20/21 long range 1v1 Saves: 13 ✅

Ah #Alisson won’t want to see this again!
There’s 2 mistakes here:
1. Positioning: he’s 6yrd out for a central 15yrd shot thus he cuts his reaction time greatly without reducing the effective goal area a lot.
2. Technique: he goes with his hand rather than his foot!

#LIVAVL
Research has shown the optimum GK position for none 1v1 long range shots is roughly 1.5-2yrd off the line
Once a GK starts positioning themselves further out than this the reduced goal area they have to cover doesn’t outweigh the loss of reaction time hence goals like this occur

In this situation though #Watkins’ finish is actually a poor one as he smashes it down the centre, so #Alisson could’ve got away with his poor positioning but he compounded his first mistake by going with his hand rather than his foot!

THREAD:
How important is a goalkeeper’s ability to prevent shots?
Is it of comparable importance to shot stopping ability?
In this thread I will investigate these questions & outline my ExG prevented model using #Alisson as an example.

#PremierLeague #LFC #GKUnion #EPL
Every action a GK performs can be separated into 3 categories:
Save-> here the GK attempts to block the ball going into the goal
Distribution-> here the GK attempts to play the ball to a teammate
Interception-> here the GK attempts to stop the ball from reaching an opponent
Save-> here the GK attempts to block the ball going into the goal
Distribution-> here the GK attempts to play the ball to a teammate
Interception-> here the GK attempts to stop the ball from reaching an opponent
Evaluating GK intercepting from public data is difficult as most stats providers split intercepting actions between recoveries, tackles, interceptions, punches, & claims, & the differences between the categories are unclear & not relevant to interception difficulty/importance.
