Analysis

Our model puts a Besiktas win at 57.7% in this Süper Lig fixture — a moderate lean. Expected goals run 1.79 to 0.91.

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 55% and 65% came in 49.9% of the time — 379 fixtures in that band. That is 9.6 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.

Evenly rated

There is almost nothing between these two on rating — 1630 against 1614, a gap of 16 points. Fixtures this evenly matched are where a model has least to say: the probabilities below are honest, but they are close to a coin weighted only slightly.

Attack against defence

The single rating hides where the mismatch actually sits. Splitting it, Istanbul Basaksehir's attack should find room against Besiktas's defence, by 106 points. That is the mechanism behind the expected-goals line rather than a separate opinion about it.

How often they shoot

Besiktas take 16.3 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

77.8% of the shots on target Besiktas face do not end up in the net, against 67.4% 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.
