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.

1

Recent form of each side

Portsmouth at homecreates 1.10, concedes 1.00 · 31 matches

Derby awaycreates 1.11, concedes 1.77 · 47 matches

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

2

Expected goals for this match

Portsmouth attack 1.10 + Derby defence 1.77 → ÷2 → 1.44

Derby attack 1.11 + Portsmouth defence 1.00 → ÷2 → 1.06

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.

4

Portsmouth at 46% 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 46% does not mean "Portsmouth will win" — it means "on the available stats, this is the most likely result."
