Strasbourg vs Paris Saint-Germain
Our model puts a Paris Saint-Germain win at 64.6% in this Ligue 1 fixture — the clearest call on this fixture. Expected goals run 0.86 to 2.07.
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 55% and 65% came in 50.7% of the time — 355 fixtures in that band. That is 8.8 points below what the model claimed, so read this figure as optimistic: in this range it has been saying more than it could support. We publish the gap rather than quietly shading the number, because a record that only shows its good bands is not a record.
Where we disagree with the market
Bookmakers price Paris Saint-Germain at 1.41, which implies about 70.9%. Our model has it at 64.6% — 6.3 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 1972 against 1699 for Strasbourg, a gap of 272 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 Strasbourg's defence, by 331 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 5 straight wins, part of 5 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.
Strasbourg are off their season peak
Strasbourg peaked at 1750 this season and sit at 1699 today, 51 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
Strasbourg hits the target more often than almost anyone: 41.4% 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.
How often they shoot
Paris Saint-Germain take 19.1 shots a match against an average of 11.9. Volume like that usually means territory rather than precision, and it is why a side can dominate a match and still not win it.
Behind the defence
76.5% of the shots on target Paris Saint-Germain face do not end up in the net, against 67.3% 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.
