Poisson Model

The Poisson distribution model projects Birmingham 1.89 xG and West Ham 1.60 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: Birmingham attack 1.333 / defence 0.875 | West Ham attack 1.403 / defence 0.981. League average goals — home 1.447 / away 1.305. Birmingham carry an above-average attack strength of 1.333 — their λ of 1.89 reflects genuine attacking quality above the league norm. West Ham have an above-average attack strength of 1.403 — the away xG of 1.60 is driven by genuine attacking quality on the road. Data: 57 Birmingham games / 11 West Ham games used (CurrentSeason).

Result probabilities: Birmingham 45% | Draw 22% | West Ham 33%. Fair-value odds: Birmingham 2.22 | Draw 4.55 | West Ham 3.03. Birmingham hold a narrow Poisson edge at 45% — the draw (22%) is close enough to merit draw-inclusive market consideration.

Goals markets: Over 2.5 probability 68% | BTTS probability 68% | Total xG 3.49. Over 2.5 is the model's clear signal at 68% — a total xG of 3.49 means the expected score alone exceeds the 2.5 threshold, making the Over not just likely but structurally supported by both sides' attack/defence profiles. BTTS Yes at 68% reflects that both xG figures (1.89 / 1.60) are above the threshold where scoring blanks become the primary outcome — both sides are projected to find the net.

Verdict

The Poisson model's primary lean is Birmingham at 45% — moderate model lean. Draw probability of 22% warrants consideration of Double Chance or Draw No Bet on Birmingham if the outright odds are short. The opposing side holds a 33% win probability per the model — this is not a banker and should be staked accordingly.

Poisson projects 3.49 total expected goals, pointing to Over 2.5 at 68% probability — reasonable conviction, supported by form averaging 3.0 goals per game.

On the BTTS market, Poisson puts 68% on Yes. Form rates corroborate: Birmingham 60% | West Ham 50% BTTS from recent games.

The outsider holds a 33% win probability per the model — this is not a banker and should not be treated as one. Proportionate stakes are appropriate given the genuine contest the data projects.
