Match Analysis
Portsmouth host Swansea at Fratton Park in Championship, Regular Season - 37. Kick-off is scheduled for Tuesday 10 March 2026 at 19:45 UTC.
Form Guide
Portsmouth — All Games: 3W 3D 4L from 10 Championship outings this season, averaging 1.20 points per game. Last five: W W L L D. They are averaging 1.30 goals per game and conceding 1.00 — a modest attacking output that tempers optimism on the Over 2.5 market. 1 clean sheet from 10 outings provides some defensive foundation. Both teams have scored in 60% of their games — a high BTTS rate that carries real weight in the goals markets.
In front of their own supporters this season, Portsmouth have posted 4W 3D 3L at Fratton Park — 1.50 PPG. At home they are averaging 1.20 goals scored and 0.80 conceded per game.
Across all Championship games this season, Swansea have recorded 5W 2D 3L from 10 outings — 1.70 PPG. Last five: L W D L W. They are scoring at 1.50 per game and conceding 1.00. 4 clean sheets in 10 outings (40%) underlines their defensive solidity.
Swansea's form when playing away from home: 2W 0D 8L across 10 road games this term (0.60 PPG). Away from home they average 0.80 goals scored and 1.80 conceded per game. Their away PPG of 0.60 is notably below their overall 1.70 — form away from home has been a clear weakness this season.
Despite the home advantage, the form figures favour Swansea — 0.50 PPG ahead of the hosts (1.70 vs 1.20). That gap is large enough to take seriously. Draw No Bet on the visitors neutralises home-ground risk while maintaining the form-backed selection.
Head to Head
There is little to separate the sides historically. From 3 previous meetings, Portsmouth have won 1, Swansea 1, with 1 draws — a balanced ledger that offers no obvious directional steer on its own.
Goals have been a feature of this fixture. The last 3 meetings have averaged 3.0 per game — a rate that gives the Over 2.5 market a solid historical foundation. The most recent clash, on 9 Dec 2025, ended 0–1 with Swansea winning.
With the win record balanced, the strongest H2H-derived signal is in the goals market. At 3.0 goals per game historically, Over 2.5 is the cleaner angle to extract from the head-to-head data.
In-Play Profile
Portsmouth in-play tendencies (81 games, 39 at home): they score before half-time in 67% of fixtures in home games; when goalless at HT, a second-half goal follows 77% of the time; BTTS occurs in 51% of their matches (home games); Over 2.5 goals lands in 51% of games (home games); they fail to score in 32% of games.
Swansea in-play tendencies (81 games, 39 at away): they score before half-time in 64% of fixtures in away games; when goalless at HT, a second-half goal follows 83% of the time; BTTS occurs in 44% of their matches (away games); Over 2.5 goals lands in 49% of games (away games).
BTTS rates are mixed from the trading data — Portsmouth 54% versus Swansea 46%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Portsmouth 53% | Swansea 46%).
Poisson Model
The Poisson distribution model projects Portsmouth 1.30 xG and Swansea 0.80 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 0.870 / defence 0.856 | Swansea attack 0.763 / defence 1.153. League average goals — home 1.291 / away 1.217. Data: 81 Portsmouth games / 82 Swansea games used (CurrentSeason).
Result probabilities: Portsmouth 47% | Draw 32% | Swansea 21%. Fair-value odds: Portsmouth 2.13 | Draw 3.12 | Swansea 4.76. Portsmouth hold a narrow Poisson edge at 47% — the draw (32%) is close enough to merit draw-inclusive market consideration.
Goals markets: Over 2.5 probability 35% | BTTS probability 41% | Total xG 2.09. Under 2.5 is the strongly backed market at 65% probability — total xG of 2.09 sits well below the 2.5 threshold. The model is projecting a tight, low-scoring match based on both sides' defensive quality. BTTS probability of 41% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.
Analysis Verdict
On the Poisson output, Portsmouth are the pick at 47% — moderate model lean. Note a divergence: in-form Swansea (1.70 PPG) cuts against the Poisson lean — consider the strength-adjusted model over surface-level form results. With a 32% draw probability, Draw No Bet on Portsmouth offers a more defensible entry point than the straight win.
Poisson projects 2.09 total expected goals, pointing to Under 2.5 at 35% probability — Poisson-only — limited corroboration conviction — though H2H averaging only 3.0 goals per meeting points in the other direction.
The Poisson model's BTTS call is No at 41%. Form rates corroborate: Portsmouth 50% | Swansea 40% BTTS from recent games.

🧮 Model Insight
Model Mechanics
The model rates Portsmouth's attack at 0.87x the league average against Swansea's defence at 1.15x — combine the two and it projects 1.30 expected goals for the hosts. The same calculation in reverse, Swansea's attack versus Portsmouth's defence, projects 0.80 expected goals for the visitors.
These ratings are built from 81/82 games of current-season data — a full enough sample to trust.
Scoreline Breakdown
Of every possible scoreline, 1-1 carries the highest individual probability at 14.4% — still a long way from a near-certainty, which says something about how open this one is on paper.

📈 Form Insight
Where Both Sides Stand
Across their last 81 outings, Portsmouth have picked up 1.16 PPG on a 24W 22D 35L record — W-W-L-L-D across the most recent five.
Swansea's form line: 31W 17D 33L from 81 games, 1.36 PPG, last five L-W-D-L-W.
Form-wise this is close to level: Portsmouth on 1.16 PPG, Swansea on 1.36. Other factors will likely decide this one more than recent results.
Home Ground vs the Road
On home soil, Portsmouth have posted 1.56 PPG from 39 outings (17W 10D 12L). That's noticeably better than their 1.16 PPG overall — Portsmouth are a different proposition at home than their general record suggests.
On the road, Swansea have gone 11W 6D 22L from 39 away games — 1.00 PPG when travelling.
Comparing the two in their relevant venue splits, Portsmouth come out ahead — a more targeted read than the overall PPG figures above, since it strips out games played in the opposite context.
The Goals Picture
Portsmouth are averaging 1.15 goals scored and 1.43 conceded per game recently; Swansea are on 1.15 scored and 1.21 conceded.

📝 Match Report
How It Unfolded
Swansea beat Portsmouth 1-2 at Fratton Park, Regular Season - 37, in the Championship. 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 Swansea 0.80 xG, a combined 2.09. The scoreboard read 1-2 for 3 actual goals. Swansea outscored their 0.80 projection by 1.2. Those figures were built on strength ratings of Portsmouth attack 0.87 / defence 0.86 against Swansea attack 0.76 / defence 1.15, drawn from 81/82 games (CurrentSeason).
On the result, the model split it Portsmouth 47% | Draw 32% | Swansea 21%, with Portsmouth to win its most likely call at 47%. Instead the game produced a Swansea win, an outcome the model had rated at just 21% — a clear break from expectation and a genuine upset by the numbers.
Goals & Markets
The model rated Over 2.5 goals at 35%. The game delivered 3, so it went over — against the model's lean. Over 1.5 had been 63% and landed. On both teams to score, the model sat at 41% and the match saw both sides score — a miss on BTTS. Historically the two sides average 49% Over 2.5 across their same-competition games (Portsmouth 53%, Swansea 46%), a base rate that pointed the other way from today's over. Their combined BTTS history runs at 50%, which matched the both-scored outcome.
Trading Patterns vs Reality
Portsmouth's trading profile (81 games, 39 home) set some clear expectations: BTTS lands in 54% of their matches — today it did.
Swansea's trading profile (81 games, 39 away) set some clear expectations: BTTS lands in 46% of their matches — today it did; they keep a clean sheet 31% of the time, and conceded here.
Form vs Result
The form lines were close — Portsmouth 1.16 PPG, Swansea 1.36 PPG — offering no strong steer, and the Swansea win broke the near-deadlock. Portsmouth (home/away splits) shipped 2 against a 0.97 concession average — a leakier day than usual. Swansea (home/away splits) scored 2 against a 0.82 average — above their attacking norm.
Verdict
Grading the result against the stored data, 0 of 3 pre-match signals came in: result (miss), Over 2.5 (miss), BTTS (miss). This one broke away from the data — most of the pre-match signals were overturned by how the ninety minutes actually played out.
