Croatia vs Spain
Our model puts a Spain win at 72.9% in this Int: UEFA Nations League fixture — the clearest call on this fixture. Expected goals run 0.78 to 2.44.
Where we disagree with the market
Bookmakers price Spain at 1.26, which implies about 79.4%. Our model has it at 72.9% — 6.5 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.
The ratings gap
Spain carry a rating of 1992 against 1750 for Croatia, a gap of 242 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, Spain's attack should find room against Croatia's defence, by 207 points. That is the mechanism behind the expected-goals line rather than a separate opinion about it.
Spain are on a run
Spain arrive on 10 straight wins, part of 41 matches unbeaten. Form of that length moves our rating on its own, so it is already reflected in the numbers above rather than being an argument on top of them.
