Sparta Rotterdam vs Willem II
Our model puts a Sparta Rotterdam win at 65.5% in this Eredivisie fixture — the clearest call on this fixture. Expected goals run 2.22 to 0.95.
What this probability has been worth
A number is worth what it has been worth. Across 1,941 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 — 183 fixtures in that band. The model claimed 69.4%, so the two are within 0.5 points of each other. In this range the stated probability has meant roughly what it says.
Where we disagree with the market
Bookmakers price Willem II at 4.5, which implies about 22.2%. Our model has it at 15.1% — 7.1 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, Sparta Rotterdam's attack should find room against Willem II's defence, by 104 points. That is the mechanism behind the expected-goals line rather than a separate opinion about it.
Willem II are off their season peak
Willem II peaked at 1500 this season and sit at 1428 today, 72 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.
Finding the target
Willem II 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.
Behind the defence
51.6% of the shots on target Sparta Rotterdam face do not end up in the net, against 67.3% for the sides we measure. That is low enough to matter, and it is the kind of number that flatters or punishes a side's record without saying much about how it plays.
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 61.6%. 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.
