What Is a Soccer Expected Goals Against (xGA) Metric
Expected Goals Against (xGA) totals the xG of all chances a team concedes, measuring defensive quality independent of the goalkeeper's shot-stopping performance.
Defensive quality measure
xGA shows how many goals a team was expected to concede based on chance quality.
Independent of finishing
A low xGA means good defending regardless of whether the opponent finished chances.
Team and player splits
Break down xGA by zone, phase, and opponent to find defensive weaknesses.
What xGA reveals
- Total expected goals conceded per match
- xGA by defensive zone and phase of play
- Comparison against actual goals conceded to isolate keeper impact
- Trend across matches to track defensive form
xGA scope
- Total xGA
- Zone splits
- Keeper isolation
- Form trends
Why xGA matters
Goals conceded can be distorted by a goalkeeper having a great or poor game. xGA strips out finishing and shot-stopping luck to reveal how well the defense actually limited chance quality, making it one of the most reliable defensive metrics in soccer.
