Expected goals in this match
What is xG?
Every shot is scored 0–1 by how likely it is to be a goal from that spot — a chance in the middle of the box ≈ 0.4, a long shot from a tight angle ≈ 0.03, a penalty ≈ 0.76. Add them up over a match and that is the xG.
The scoreline can lie: you can win 1-0 on a fluke while creating half the chances. xG shows who was really closer to scoring — and over a season it predicts results better than goals alone.

How is this calculated?
Every number below comes from this match — nothing is made up.
Recent form of each side
Union San Felipe at home — creates 1.22, concedes 0.92 · 111 matches
Antofagasta away — creates 1.12, concedes 1.47 · 57 matches
⚑ Home and away form are counted separately — the home-field edge is already baked into these numbers.
Expected goals for this match
Union San Felipe attack 1.22 + Antofagasta defence 1.47 → ÷2 → 1.34
Antofagasta attack 1.12 + Union San Felipe defence 0.92 → ÷2 → 1.02
Each side's attack is blended with the other's defence, then averaged.
Chance of every scoreline
From those two numbers a Poisson distribution gives the probability of each exact score — the grid shown above.
The answer to "why 44%?"
Union San Felipe at 44% is simply the biggest of the three — that is the pick.
What the model can't see
It reads only the stats of recent matches. It knows nothing about:
- injuries & suspensions
- the matchday lineup
- motivation — cup, relegation, a title race
- weather & pitch condition
- in-game coaching decisions
So 44% does not mean "Union San Felipe will win" — it means "on the available stats, this is the most likely result."
