xG Statistics

Jack Jasinski is not yet matched to an Understat player model, so there are no xG rows. When the mapping appears, this block will show appearances, minutes, goals, xG, npxG, assists, xA, shots, key passes and xGChain for each available season.

Understat has no season rows for this player yet.

What the columns mean

Read this table as chance quality, not as a scoreboard. A player can outscore xG (finishing well) or lag behind it (missed sitters). Compare rows only when minutes are in the same range.

Apps · Appearances
Matches in which the player was used in this league season, including substitute minutes.
Min · Minutes
Total minutes on the pitch. Useful when comparing output: 1 goal in 90 minutes is not the same as 1 goal in 800.
G · Goals
Goals credited to the player in the Understat shot model for that season.
xG · Expected goals
The quality of shots the player took, expressed as the number of goals an average finisher would score from the same chances. A 0.30 xG shot is a chance that goes in about 3 times in 10.
npxG · Non-penalty xG
Expected goals with penalties removed. This is the cleaner read of open-play and set-piece finishing, because a penalty is usually ~0.76 xG by itself.
A · Assists
Goals that followed the player's last pass. Actual assists, not the model.
xA · Expected assists
The xG value of shots that came directly from the player's key passes. High xA with few assists usually means teammates missed good chances.
Sh · Shots
Total shots recorded by Understat, including blocked and off-target attempts.
KP · Key passes
Passes that led to a shot. This is the volume behind xA.
xGChain · xG chain
Team xG from possessions the player touched. It captures involvement in build-up, not only the shot or the last pass. A midfielder who starts attacks can rank high here without scoring.
xGBuildup · xG buildup
The same possession xG, but excluding the shot-taker and the assist. This is the purest 'how much did this player help create the chance before the final ball' number.
NPG · Non-penalty goals
Goals scored from open play or set pieces, excluding penalties.
