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!
