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
Adelaide Olympic at home — creates 1.70, concedes 0.80 · 20 matches
West Adelaide away — creates 1.53, concedes 1.28 · 47 matches
⚑ Home and away form are counted separately — the home-field edge is already baked into these numbers.
Expected goals for this match
Adelaide Olympic attack 1.70 + West Adelaide defence 1.28 → ÷2 → 1.49
West Adelaide attack 1.53 + Adelaide Olympic defence 0.80 → ÷2 → 1.17
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 45%?"
Adelaide Olympic at 45% 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 45% does not mean "Adelaide Olympic will win" — it means "on the available stats, this is the most likely result."
