Challenge League · Friday, 30 October 2026 · 19:15. Our rating makes this 66% to go over 2.5 goals, so our lean is over. The Challenge League average is 61%.
| Market | Yes | No | Our call |
|---|---|---|---|
| Over 2.5 goals | 66% | 34% | Over |
| Over 3.5 goals | 40% | 60% | no pick |
| Both teams to score | 63% | 37% | Yes |
The result model puts Neuchatel Xamax FC at 41%, the draw at 23% and FC Aarau at 36%, from expected goals of 1.87 and 1.74.
The league sets the starting point. Challenge League has produced over 2.5 goals in 61% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Neuchatel Xamax FC have 9 in 10 this season (5 of 5 at home), FC Aarau 9 in 10 (5 of 5 away). Those records are pulled toward the league rate with the weight of about 24 matches — enough that two or three unusual games cannot swing a rating — giving 70% and 70%.
Last season still counts, briefly. With 10 and 10 games played this season, last season's rates are still blended in and fade out entirely by game 40 — the point at which our testing showed they stop adding accuracy. A single season is part luck, so each club's record is first pulled toward the league average by 34 games' weight. That moves the two figures to 66% and 66%.
The mix. Weighted 40% home side, 40% away side and 20% league — the split that beat every alternative across 30,582 matches of testing — that gives 65%.
Head to head. These sides have met 12 times in three years, producing over 2.5 goals in 58%. That nudges the number 5% of the way toward the head-to-head pattern — deliberately small, because fixtures change more than reputations do — landing on 65%.
Goal expectation. Separately a Poisson model built from attack and defence strength — using real expected-goals data where the league has it — puts this match at 70%, from expected goals of 1.87 for Neuchatel Xamax FC and 1.74 for FC Aarau. Folding in 30% of that view gives 66%.
This breakdown is generated from the same inputs the rating uses, so it cannot describe a calculation we did not perform. The full model is set out in the methodology.
| Team | Games | O2.5 | O3.5 | BTTS |
|---|---|---|---|---|
| Neuchatel Xamax FC | 10 | 90% | 30% | 60% |
| FC Aarau | 10 | 90% | 30% | 90% |
Our numbers give this match a 75% chance of at least one goal before half-time and 47% of two or more. The Challenge League rates are 72% and 46%. After the break: 83% for a goal and 47% for two or more (league 81% and 48%). Neuchatel Xamax FC's last 50 games had a first-half goal 82% of the time and a second-half goal 84%; FC Aarau's last 50, 76% and 88%. Team form says less about a single half than about a full match, so these numbers stay close to the league's.
Every match ranked the same way: first half goals today · second half goals today · tomorrow.
