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.

1

Recent form of each side

Nairobi City Stars at home — creates 1.18, concedes 1.09 · 85 matches

Western Stima away — creates 0.94, concedes 1.35 · 51 matches

⚑ Home and away form are counted separately — the home-field edge is already baked into these numbers.

2

Expected goals for this match

Nairobi City Stars attack 1.18 + Western Stima defence 1.35 → ÷2 → 1.27

Western Stima attack 0.94 + Nairobi City Stars defence 1.09 → ÷2 → 1.02

Each side's attack is blended with the other's defence, then averaged.

3

Chance of every scoreline

From those two numbers a Poisson distribution gives the probability of each exact score — the grid shown above.

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 42% does not mean "Nairobi City Stars will win" — it means "on the available stats, this is the most likely result."
