Poisson Model

The Poisson distribution model projects Nacional 1.64 xG and Vitória SC 1.15 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 1.088 / defence 1.010 | Vitória SC attack 0.889 / defence 1.138. League average goals — home 1.324 / away 1.283. Data: 39 Nacional games / 38 Vitória SC games used (CurrentSeason).

Result probabilities: Nacional 49% | Draw 24% | Vitória SC 27%. Fair-value odds: Nacional 2.04 | Draw 4.17 | Vitória SC 3.70. Nacional hold a narrow Poisson edge at 49% — the draw (24%) is close enough to merit draw-inclusive market consideration.

Goals markets: Over 2.5 probability 53% | BTTS probability 55% | Total xG 2.79. Over/Under 2.5 is close to a coin-flip at 53%/47% — the total xG of 2.79 sits near the 2.5 margin; this is a low-edge market from a Poisson standpoint. BTTS probability of 55% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Analysis Verdict

On the Poisson output, Nacional are the pick at 49% — moderate model lean. With a 24% draw probability, Draw No Bet on Nacional offers a more defensible entry point than the straight win.

The Poisson model projects 2.79 xG in total — Over 2.5 at 53% — Poisson-only — limited corroboration confidence.

On the BTTS market, Poisson puts 55% on Yes. This conflicts with form data: Nacional 30% | Vitória SC 50% from recent games — a notable divergence.
