xG Statistics
Sebastian Szymański's xG Statistics block is an Understat shot model for the 2026 season. It does not replace goals and assists — it explains them. xG and xA ask whether the chances were good enough; xGChain and xGBuildup show how often the player was on the ball in moves that became shots. Use minutes as the denominator: a large xG in 80 minutes is a hot streak, the same xG over 1,200 minutes is a role. Figures are rounded to two decimals and stay empty when Understat has no match for this player.
| Season | League | Club | Apps | Min | G | xG | npxG | A | xA | Sh | KP | xGChain |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 2026 | Ligue 1 | Rennes | 2 | 143 | 0 | 0.06 | 0.06 | 1 | 0.18 | 2 | 4 | 1.78 |
| 2025 | Ligue 1 | Rennes | 16 | 796 | 1 | 0.53 | 0.53 | 3 | 2.57 | 12 | 19 | 4.68 |
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.
