Napoli vs Bologna
Our model puts a Napoli win at 52.4% in this Serie A fixture — a moderate lean. Expected goals run 1.58 to 0.93.
Where we disagree with the market
Bookmakers price Napoli at 1.71, which implies about 58.5%. Our model has it at 52.4% — 6.1 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 Bologna's defence, by 118 points. That is the mechanism behind the expected-goals line rather than a separate opinion about it.
Margin risk
Our blowout flag reads 50%: more than half of all simulations end with a three-goal margin or more. Finishing gaps that wide make the scoreline far less predictable than the winner.
