Villarreal vs Napoli
Our model puts a Napoli win at 37% in this UEFA Champions League fixture — close to a three-way split. Expected goals run 1.28 to 1.3.
What this probability has been worth
A number is worth what it has been worth. Across 1,876 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 — 705 fixtures in that band. The model claimed 40.6%, so the two are within 1.9 points of each other. In this range the stated probability has meant roughly what it says.
Where we disagree with the market
Bookmakers price Villarreal at 2.15, which implies about 46.5%. Our model has it at 36.3% — 10.2 points lower. That is a wide gap, and it is worth being plain about what it means: it is not a claim that the price is wrong and we are right. It means two methods that usually agree have landed far apart on this one, and only the result will say which of them read it better.
Attack against defence
The single rating hides where the mismatch actually sits. Splitting it, Napoli's attack should find room against Villarreal's defence, by 189 points. That is the mechanism behind the expected-goals line rather than a separate opinion about it.
Early or late
41.7% of Villarreal's goals have come after the break, against 55.6% for the sides we measure, over 24 goals. A side that does its scoring early has more to protect than most, and a lead at the break is likelier to be the story of the match than the first act of it.
Behind the defence
78.6% of the shots on target Napoli face do not end up in the net, against 67.4% for the sides we measure. That is a keeper and a defence having a good run of it — and a figure that tends to drift back toward the middle, which is worth remembering before reading too much into it.
