How to Read World Cup xG: Lessons From the 2022 Final

Understand World Cup expected goals using the 2022 final, with clear explanations of penalties, extra time and misleading tournament totals.

Expected goals (xG) measures the quality of the shots a team takes—not the score it was guaranteed to achieve. At the World Cup, it helps explain why a level score can conceal an uneven balance of chances. But penalties, extra time and unequal numbers of matches make the tournament’s figures easy to misread.

The men’s 2022 final between Argentina and France is a useful example: the score was level after both normal time and extra time, yet Argentina finished with the higher xG.

What the number measures

An xG model assigns each shot a scoring probability between 0 and 1. A shot worth 0.20 xG represents an estimated 20% chance of scoring, based on the model’s assessment of comparable situations. Common inputs include distance, angle, body part and the action preceding the shot; some models also include goalkeeper and defender positions. Hudl Statsbomb explains these inputs and why models produce different values.

A team’s match xG adds those shot values together. It is a total, not a percentage: 2.00 xG does not mean a 200% chance of winning, nor does it promise two goals. It describes the expected scoring output of the shots taken. Attacks that never produce a shot do not add to ordinary shot-based xG.

There is no minutes denominator in that raw total. Rates such as xG per 90 introduce one: total xG divided by minutes played, multiplied by 90.

The 2022 final: same score, different chance quality

Sporting Life’s review reported the following figures from Infogol’s model. The 120-minute figures are cumulative, not extra time alone. Both windows include their respective stoppage time.

Match window Actual score, Argentina–France Argentina xG France xG
Normal time (90 minutes) 2–2 1.77 1.09
Including extra time (120 minutes) 3–3 3.45 2.29

The first row shows why xG adds information beyond the score. France matched Argentina’s two goals in normal time despite recording a lower total estimated chance value. That is not a contradiction: shots either become goals or do not, while xG expresses probabilities.

The second row also changes the interpretation. Argentina added 1.68 xG during extra time, calculated by subtracting its normal-time total from its 120-minute total. Reading 3.45 as a 90-minute figure would exaggerate its chance production rate.

Nor does Argentina’s higher xG establish that it was certain to win. France still had a late opportunity: Infogol valued Randal Kolo Muani’s chance, saved by Emiliano Martínez near the end of extra time, at 0.33 xG. A lower-xG team can still create the chance that decides a knockout match. The same review records that opportunity.

Separate penalties from the shootout

Three of the final’s six match goals were penalties: one for Argentina and two for France. Argentina then won the shootout 4–2. The Coaches’ Voice match analysis confirms the scoring sequence and outcome.

Those are two different statistical categories:

  • Penalties during the match contribute to ordinary xG totals, unless the display specifies non-penalty xG, or npxG.
  • Shootout kicks should be kept separate from match xG and match goals. Under IFAB Law 10, the shootout takes place after the match has ended.

The distinction matters here. Sporting Life reported just 0.29 non-penalty xG for France in normal time, compared with its 1.09 total xG. France’s penalty accounted for much of its estimated chance value in that window.

Non-penalty xG helps you examine chances beyond spot kicks. It is not the same as open-play xG: non-penalty totals can still include shots from corners and free kicks.

How to compare World Cup teams

Before interpreting a tournament xG table, check:

  • Edition and competition: specify the year and whether it is the men’s or women’s World Cup. A single-edition table is not an all-time ranking.
  • Provider: use one model throughout. Different models can value the same shot differently.
  • Playing time: teams progressing further have more opportunities to accumulate xG. Use per-90 rates when comparing production rates, with extra-time minutes included if the xG includes extra-time shots. Still consider opponents and match situations.
  • Penalties and extra time: check whether penalties are included and whether knockout totals cover 90 or 120 minutes.
  • Both directions: xG measures chances taken; xGA measures chances conceded. xG difference is xG minus xGA, not actual goal difference.

Even a per-90 comparison does not remove the uncertainty of a short tournament. A few penalties, difficult opponents or unusually good finishes can strongly influence the figures. Use World Cup xG to assess the shots teams created and allowed—not to turn a handful of matches into a definitive ranking of team quality.
