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.

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

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.

Dean #Henderson vs David #DeGea
#PremierLeague Shotstopping 19/20
As requested I will compare the shot stopping performances of the two potential #ManchesterUnited number 1’s.
There will be statistics & 1v1 plots!

Firstly let’s look at post shot expected goals conceded.
@StatsBomb’s PSExG model takes the position of the shot, the position of the defenders, the speed of the shot & the placement of the shot into account in order to calculate whether an Avg GK would save it.

Using this model #DeGea has played almost exactly to the level of an average #PremierLeague goalkeeper & has conceded -0.2 goals more than expected.
#Henderson on the other hand has saved #SheffieldUnited +6.5 more goals than an avg GK would be expected to!
