Internazionale vs Fiorentina
Our model puts an Internazionale win at 69.3% in this Serie A fixture — the clearest call on this fixture. Expected goals run 2.2 to 0.77.
What this probability has been worth
A number is worth what it has been worth. Across 2,054 predictions published before kick-off and scored against the result afterwards, the calls we priced between 65% and 75% came in 69.9% of the time — 193 fixtures in that band. The model claimed 69.4%, so the two are within 0.6 points of each other. In this range the stated probability has meant roughly what it says.
The ratings gap
Inter Milan carry a rating of 1848 against 1667 for Fiorentina, a gap of 181 points. On our scale that is the difference between a side that controls most of its fixtures and one that has to earn each of them. It is also the single largest input into the probabilities above.
Attack against defence
The single rating hides where the mismatch actually sits. Splitting it, Internazionale's attack should find room against Fiorentina's defence, by 290 points. That is the mechanism behind the expected-goals line rather than a separate opinion about it.
Internazionale are off their season peak
Internazionale peaked at 1904 this season and sit at 1848 today, 56 points below their own best. Measuring a side against itself rather than against the table is often the earlier signal, and it is not visible in a league position.
A high-scoring home side
One model here does nothing but estimate how likely the home side is to score four goals or more, and on this fixture it reads 69%. Across our settled fixtures that happens about 8% of the time, so this is well above ordinary. It says nothing about who wins — a side can score four and still be caught — but a match where one team is expected to run up a total is one where the scoreline is much harder to call than the result.
