Paris Saint-Germain vs Troyes
Our model puts a Paris Saint-Germain win at 82.5% in this Ligue 1 fixture — the clearest call on this fixture. Expected goals run 2.65 to 0.48.
What this probability has been worth
A number is worth what it has been worth. Across 2,454 predictions published before kick-off and scored against the result afterwards, the calls we priced between 75% and 85% came in 84.1% of the time — 88 fixtures in that band. The model claimed 79.2%, so the two are within 4.9 points of each other. In this range the stated probability has meant roughly what it says.
Where we disagree with the market
Bookmakers price Paris Saint-Germain at 1.12, which implies about 89.3%. Our model has it at 82.5% — 6.8 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
Paris Saint Germain carry a rating of 2000 against 1527 for Troyes, a gap of 472 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, Paris Saint-Germain's attack should find room against Troyes's defence, by 386 points. That is the mechanism behind the expected-goals line rather than a separate opinion about it.
Paris Saint-Germain are on a run
Paris Saint-Germain arrive on 9 straight wins, part of 9 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.
Finding the target
Troyes struggles to hit the target: 23.5% of their shots are on goal over their last matches. The average across the sides we have figures for is 33.9%. 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.
How often they shoot
Paris Saint-Germain take 18.9 shots a match against an average of 12. Volume like that usually means territory rather than precision, and it is why a side can dominate a match and still not win it.
Early or late
69.6% of Paris Saint-Germain's goals have come after the break, against 56.2% for the sides we measure, over 23 goals. A side that scores this late is usually one that grows into matches or finishes them stronger than it starts — and one whose half-time score says less than usual about the result.
Behind the defence
80% of the shots on target Paris Saint-Germain face do not end up in the net, against 67.2% 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.
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 82.2%. 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.
