Low scoring is structural: only 3 of 11 seasons exceeded 2.70 goals/match. Since 2018/19: consistently 2.48–2.69. 2021/22: 11.3% goalless draws — a record across all leagues and seasons in the dataset. 2025/26: home wins surged to 48.9% — the strongest home season in the dataset, reinforcing the favourite bias.
The Barcelona–Real Madrid duopoly
| Team | Matches | Win % | Goals/match |
|---|---|---|---|
| Barcelona | 418 | 70.3% | 3.32 |
| Real Madrid | 418 | 67.7% | 3.09 |
| Atlético Madrid | 418 | 60.0% | 2.49 |
| Sevilla | 418 | 41.9% | 2.63 |
| Valencia | 418 | 34.4% | 2.58 |
Barça and Real win ~68–70%, producing 3.09–3.32 goals/match (vs 2.63 league avg). Atlético: 60.0% wins but only 2.49 goals — the defensive archetype. Sevilla (41.9%) and Valencia (34.4%) are closer to EPL mid-table than Spanish elite. This polarization drives the calibration gaps.
Market calibration: the +6.0pp favourite gap
| Cluster | n | Imp H | Act H | Δ H | Imp D | Act D | Δ D | Δ A |
|---|---|---|---|---|---|---|---|---|
| Heavy Fav | 586 | 75.0% | 81.1% | +6.0pp | 16.0% | 13.1% | −2.9 | −3.1 |
| Clear Fav | 923 | 56.8% | 58.2% | +1.3 | 25.0% | 25.8% | +0.7 | −2.0 |

| Underdog | 1,093 | 23.1% | 21.8% | −1.3 | 26.1% | 26.3% | +0.2 | +1.1 |
Heavy Fav +6.0pp is the single largest cluster gap in the entire 19,381-match dataset: Barça and Real win 81.1% at home where the market implies 75.0%. A secondary anomaly persists in Even matches, where draws hit 34.3% vs 29.9% implied (+4.5pp). Both stem from the same source — a polarized league where elite home teams dominate and mid-table sides stalemate.

ROI breakdown by cluster
| Cluster | n | Home | Draw | Away |
|---|---|---|---|---|
| Heavy Fav | 586 | +3.3% | −20.1% | −30.8% |
| Clear Fav | 923 | −3.3% | −2.7% | −16.4% |
| Slight Fav | 920 | −2.1% | −6.9% | −8.4% |
| Even | 658 | −8.6% | +9.5% | −15.0% |
| Underdog | 1,093 | −7.1% | −4.6% | −2.6% |
Draw in Even: +9.5% — direct consequence of the +4.5pp gap. Draw odds 3.00–3.60, actual rate 34.3% vs 29.9% implied. One of the few positive-ROI pockets in the dataset.
Home as Heavy Fav: +3.3% — Barça/Real win 81.1% at odds 1.20–1.45. A modest retrospective edge.
⚠ Retrospective ROI across 11 seasons — not a betting signal. These clusters reflect historical mispricing that the bookmaker margin largely absorbs; the pattern may not persist forward.
Dixon-Coles ρ for La Liga
ρ = −0.007 — effectively zero. Smallest of any league.
Counterintuitive: La Liga has the most 0:0 draws (7.3%), yet needs no DC correction. Why? Low λ (1.50, 1.13) means Poisson already predicts a reasonable 0:0 probability (~7.3%). Gap is near zero. In contrast, Bundesliga's high λ pushes Poisson 0:0 to ~4.7% vs actual 5.6% — hence ρ = −0.096.
For La Liga in the calculator: Poisson and Adjusted DC produce nearly identical results. Cross-league comparison →
