Fixture Analysis
It is a Championship clash, Regular Season - 17 as Portsmouth welcome West Ham to Fratton Park. Kick-off is set for Tuesday 24 November 2026 at 19:45 UTC.
Recent Form
Across all Championship games this season, Portsmouth have gone 4W 4D 2L from 10 outings — a 1.60 PPG return. Last five: W W D W D. They are averaging 1.10 goals per game and conceding 0.90 — a modest attacking output that tempers optimism on the Over 2.5 market. 4 clean sheets in 10 games (40%) reflects a solid defensive base. This season is still relatively young for Portsmouth, so this record blends games from this season and last.
Portsmouth at Fratton Park this season: 5W 3D 2L from 10 home games — 1.80 PPG on home soil. At home they are averaging 1.60 goals scored and 1.30 conceded per game. BTTS has landed in 60% of their home matches — a rate that supports the Yes angle in this fixture.
Looking at all fixtures this season, West Ham stand at 6W 2D 2L from 10 Championship matches — 2.00 PPG. Last five: D W W L L. Their attacking form is sharp — 2.90 goals per game is a high-output rate that commands respect in the goals markets. 4 clean sheets in 10 outings (40%) underlines their defensive solidity. Both teams have scored in 60% of their games — a noteworthy BTTS rate that supports the Yes market. This season is still relatively young for West Ham, so this record blends games from this season and last.
West Ham away from home this season: 3W 4D 3L from 10 away games — 1.30 PPG on the road. Away from home they average 1.60 goals scored and 1.50 conceded per game. Their away PPG of 1.30 is notably below their overall 2.00 — form away from home has been a clear weakness this season.
The form comparison is too close to call — 1.60 PPG (Portsmouth) versus 2.00 (West Ham). When the figures are this level, no pick can be reliably derived from recent results alone.
In-Play Data
Portsmouth trading profile (51 games, 25 at home): they score before half-time in 72% of fixtures in home games; when goalless at HT, a second-half goal follows 82% of the time; BTTS occurs in 52% of their matches (home games); Over 2.5 goals lands in 44% of games (home games).
West Ham trading profile (51 games, 25 at away): they score before half-time in 76% of fixtures in away games; when goalless at HT, a second-half goal follows 86% of the time; two or more arrive in the second half on 64% of those occasions; BTTS occurs in 52% of their matches (away games); Over 2.5 goals lands in 60% of games (away games); Over 3.5 in 37%.
BTTS rates are mixed from the trading data — Portsmouth 55% versus West Ham 57%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Portsmouth 45% | West Ham 65%).
Poisson Model
The Poisson distribution model projects Portsmouth 1.42 xG and West Ham 1.95 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: Portsmouth attack 1.016 / defence 1.125 | West Ham attack 1.352 / defence 0.923. League average goals — home 1.517 / away 1.283. West Ham have an above-average attack strength of 1.352 — the away xG of 1.95 is driven by genuine attacking quality on the road. Data: 59 Portsmouth games / 13 West Ham games used (CurrentSeason).
Result probabilities: Portsmouth 28% | Draw 22% | West Ham 50%. Fair-value odds: Portsmouth 3.57 | Draw 4.55 | West Ham 2.00. West Ham hold a narrow Poisson edge at 50% — the draw (22%) is close enough to merit draw-inclusive market consideration.
Goals markets: Over 2.5 probability 66% | BTTS probability 65% | Total xG 3.37. Over 2.5 is the model's clear signal at 66% — a total xG of 3.37 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 65% reflects that both xG figures (1.42 / 1.95) are above the threshold where scoring blanks become the primary outcome — both sides are projected to find the net.
Summary & Verdict
The Poisson model's primary lean is West Ham at 50% — moderate model lean. With a 22% draw probability, Draw No Bet on West Ham offers a more defensible entry point than the straight win. The opposing side holds a 28% win probability per the model — this is not a banker and should be staked accordingly.
The Poisson model projects 3.37 xG in total — Over 2.5 at 66% — reasonable confidence, supported by form averaging 3.0 goals per game.
On the BTTS market, Poisson puts 65% on Yes. Form rates corroborate: Portsmouth 60% | West Ham 50% BTTS from recent games.
