Poisson Model

The Poisson distribution model projects Nacional 1.66 xG and Alverca 1.05 xG. These expected goals figures are the primary input: they feed a goal-probability matrix across all scoreline combinations to derive the result and market probabilities below. Underlying strength ratings: Nacional attack 1.086 / defence 1.016 | Alverca attack 0.821 / defence 1.145. League average goals — home 1.337 / away 1.260. Data: 38 Nacional games / 38 Alverca games used (CurrentSeason).

Result probabilities: Nacional 52% | Draw 24% | Alverca 24%. Fair-value odds: Nacional 1.92 | Draw 4.17 | Alverca 4.17. Nacional hold a narrow Poisson edge at 52% — the draw (24%) is close enough to merit draw-inclusive market consideration.

Goals markets: Over 2.5 probability 51% | BTTS probability 53% | Total xG 2.71. Over/Under 2.5 is close to a coin-flip at 51%/49% — the total xG of 2.71 sits near the 2.5 margin; this is a low-edge market from a Poisson standpoint. BTTS probability of 53% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Our Verdict

Poisson rates Nacional as the most likely outcome at 52% — moderate model lean. With a 24% draw probability, Draw No Bet on Nacional offers a more defensible entry point than the straight win.

On the goals line, Poisson's 2.71 combined xG gives a 51% probability to Over 2.5 — Poisson-only — limited corroboration.

Poisson assigns a 53% probability to BTTS Yes based on the attack/defence strength model. Form rates are neutral: Nacional 30% | Alverca 60%.
