Analysis

Our model puts a Millwall win at 40.2% in this Championship fixture — close to a three-way split. Expected goals run 1.18 to 1.33.

What this probability has been worth

A number is worth what it has been worth. Across 1,904 predictions published before kick-off and scored against the result afterwards, the calls we priced between 35% and 45% came in 38.7% of the time — 700 fixtures in that band. The model claimed 40.6%, so the two are within 1.8 points of each other. In this range the stated probability has meant roughly what it says.

Finding the target

Millwall struggles to hit the target: 27.3% of their shots are on goal over their last matches. The average across the sides we have figures for is 34.1%. Accuracy is not the same as scoring — it says how much of a side's shooting is worth a goalkeeper's attention, which is the part that does not swing as wildly from week to week as goals do.

Early or late

70.6% of Portsmouth's goals have come after the break, against 56.2% for the sides we measure, over 17 goals. A side that scores this late is usually one that grows into matches or finishes them stronger than it starts — and one whose half-time score says less than usual about the result.
