Match Analysis
Portsmouth host Stevenage at Fratton Park in League One, Regular Season - 26. Kick-off is scheduled for Monday 1 January 2024 at 15:00 UTC.
Form Guide
Portsmouth — All Games: 5W 3D 2L from 10 League One outings this season, averaging 1.80 points per game. Last five: W W D L D. Offensively they are averaging 1.70 goals per game, with 1.10 conceded. 5 clean sheets from 10 games (50%) is a standout defensive return — they are keeping their net clean in more than half their matches. This season is still relatively young for Portsmouth, so this record blends games from this season and last.
Portsmouth's home record at Fratton Park: 6W 3D 1L from 10 League One appearances (2.10 PPG). At home they are averaging 1.50 goals scored and 1.00 conceded per game. 4 home clean sheets from 10 games (40%) — a solid defensive base on their own ground.
Across all League One games this season, Stevenage have recorded 6W 3D 1L from 10 outings — 2.10 PPG. Last five: D W D L W. They are scoring at 1.80 per game and conceding 0.80. Defensively, 0.80 goals conceded per game is elite-level — a side this difficult to score against is a real threat to Over 2.5 and BTTS Yes. 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 Stevenage, so this record blends games from this season and last.
On the road, Stevenage have gone 5W 1D 4L from 10 away fixtures this term (1.60 PPG). Away from home they average 1.60 goals scored and 1.20 conceded per game. 4 clean sheets from 10 away games (40%) shows they are capable of shutting up shop on the road. Their away PPG of 1.60 is notably below their overall 2.10 — form away from home has been a clear weakness this season.
The form comparison is too close to call — 1.80 PPG (Portsmouth) versus 2.10 (Stevenage). When the figures are this level, no pick can be reliably derived from recent results alone.
H2H Record
There is little to separate the sides historically. From 1 previous meetings, Portsmouth have won 0, Stevenage 0, with 1 draws — a balanced ledger that offers no obvious directional steer on its own.
The last 1 meetings have been tight affairs, averaging just 0.0 goals per game. That low-scoring pattern is a meaningful historical input for the Under 2.5 market. The most recent clash, on 26 Aug 2023, ended 0–0 with a draw.
With a balanced win record and just 0.0 goals per game historically, the H2H points toward a tight, low-scoring contest. Under 2.5 goals has the strongest statistical grounding from the fixture history regardless of which side wins.
In-Play Data
Portsmouth trading profile (70 games, 35 at home): they score before half-time in 63% of fixtures in home games; when goalless at HT, a second-half goal follows 61% of the time; BTTS occurs in 54% of their matches (home games); Over 2.5 goals lands in 43% of games (home games); they keep a clean sheet 41% of the time.
Stevenage trading profile (70 games, 35 at away): they score before half-time in 80% of fixtures in away games; when goalless at HT, a second-half goal follows 70% of the time; BTTS occurs in 49% of their matches (away games); Over 2.5 goals lands in 40% of games (away games); they keep a clean sheet 43% of the time.
BTTS rates are mixed from the trading data — Portsmouth 50% versus Stevenage 46%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Portsmouth 43% | Stevenage 43%).
Poisson Model
The Poisson distribution model projects Portsmouth 1.30 xG and Stevenage 1.28 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 0.994 / defence 1.022 | Stevenage attack 1.118 / defence 0.961. League average goals — home 1.365 / away 1.122. Data: 70 Portsmouth games / 24 Stevenage games used (CurrentSeason).
Result probabilities: Portsmouth 37% | Draw 28% | Stevenage 36%. Fair-value odds: Portsmouth 2.70 | Draw 3.57 | Stevenage 2.78. This is a low-confidence result — no outcome exceeds 45%. The draw at 28% is a primary outcome, not an afterthought.
Goals markets: Over 2.5 probability 48% | BTTS probability 53% | Total xG 2.59. Over/Under 2.5 is close to a coin-flip at 48%/52% — the total xG of 2.59 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 Portsmouth as the most likely outcome at 37% — marginal model lean. With a 28% draw probability, Draw No Bet on Portsmouth offers a more defensible entry point than the straight win. The opposing side holds a 36% win probability per the model — this is not a banker and should be staked accordingly.
Poisson projects 2.59 total expected goals, pointing to Under 2.5 at 48% probability — Poisson-only — limited corroboration conviction.
The Poisson model's BTTS call is Yes at 53%. Form rates are neutral: Portsmouth 50% | Stevenage 40%.
The outsider holds a 36% 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.

📝 Match Report
How It Unfolded
Portsmouth beat Stevenage 2-1 at Fratton Park, Regular Season - 26, in the League One. The remainder of the report sets that outcome against the pre-match model, the markets and the teams' data profiles.
The Model vs The Result
The Poisson model went into this projecting Portsmouth 1.30 xG and Stevenage 1.28 xG, a combined 2.59. The scoreboard read 2-1 for 3 actual goals. Both sides finished within a goal of their individual projections, so the scoreline sat close to the model's expected shape. Those figures were built on strength ratings of Portsmouth attack 0.99 / defence 1.02 against Stevenage attack 1.12 / defence 0.96, drawn from 70/24 games (CurrentSeason).
On the result, the model split it Portsmouth 37% | Draw 28% | Stevenage 36%, with Portsmouth to win its most likely call at 37%. The result followed the model's preferred path, landing its top-rated outcome.
Goals & Markets
The model rated Over 2.5 goals at 48%. The game delivered 3, so it went over — against the model's lean. Over 1.5 had been 74% and landed. On both teams to score, the model sat at 53% and the match saw both sides score — another call in the model's favour. Historically the two sides average 43% Over 2.5 across their same-competition games (Portsmouth 43%, Stevenage 43%), a base rate that pointed the other way from today's over. Their combined BTTS history runs at 48%, which did not match the both-scored outcome.
Trading Patterns vs Reality
Portsmouth's trading profile (70 games, 35 home) set some clear expectations: BTTS lands in 50% of their matches — today it did; they keep a clean sheet 41% of the time, and conceded here.
Stevenage's trading profile (70 games, 35 away) set some clear expectations: BTTS lands in 46% of their matches — today it did; they keep a clean sheet 43% of the time, and conceded here.
Form vs Result
The form lines were close — Portsmouth 1.71 PPG, Stevenage 1.83 PPG — offering no strong steer, and the Portsmouth win broke the near-deadlock. Stevenage (home/away splits) shipped 2 against a 1.03 concession average — a leakier day than usual.
Verdict
Grading the result against the stored data, 2 of 3 pre-match signals came in: result (hit), Over 2.5 (miss), BTTS (hit). Partial vindication: some calls landed, others slipped.
