Mamelodi Sundowns v Siwelele — prediction, stats and goal analysis

PSL · Wednesday, 9 September 2026. Final score 3–0 (half-time 0–0). Rebuilt from the season as it stood that morning, our rating would have been 45% for over 2.5 goals. This match is older than our frozen ratings ledger, which keeps 30 days, so that figure is a reconstruction from pre-match data rather than a number we published at the time — a distinction worth making, because only the frozen ones prove what we actually said beforehand.

How we got this number

The league sets the starting point. PSL has produced over 2.5 goals in 31% of its matches, and that is where a team with no record of its own would sit.

Each side's own record. Mamelodi Sundowns have 3 in 6 this season (1 of 3 at home), Siwelele 2 in 5 (1 of 3 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 34% and 32%.

Last season still counts, briefly. With 6 and 5 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 34% and 24%.

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 29%.

Head to head. These sides have met 2 times in three years, producing over 2.5 goals in 50%. 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 30%.

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 72%, from expected goals of 3.05 for Mamelodi Sundowns and 0.69 for Siwelele. Folding in 30% of that view gives 43%.

Calibration. Tested against 97,729 past matches, our ratings below 55% have run consistently too pessimistic — a figure in the high 30s, for instance, has come in about four points higher. So ratings in that range are lifted part-way back, giving 45%.

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.
