✍️ Match Preview

Analysis

Charlton make the trip to Fratton Park to face Portsmouth in Championship, Regular Season - 31. The match kicks off on Saturday 13 February 2027 at 15:00 UTC.

Current Form

Portsmouth's overall Championship record this term: 5W 4D 1L from 10 games (1.90 PPG). Last five: W D W D W. They are averaging 1.40 goals per game and conceding 0.80 — a modest attacking output that tempers optimism on the Over 2.5 market. Defensively, conceding just 0.80 per game is an exceptional defensive record — one of the tightest in the division. 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.

In front of their own supporters this season, Portsmouth have posted 6W 2D 2L at Fratton Park — 2.00 PPG. At home they are averaging 1.70 goals scored and 1.20 conceded per game. BTTS has landed in 60% of their home matches — a rate that supports the Yes angle in this fixture.

Charlton (all games): 0W 4D 6L across 10 Championship outings this term — 0.40 points per game. Last five: D L L L L. Their scoring rate of 0.50 per game is modest, conceding 1.90 — not a side to back heavily on the Over 2.5 from their form alone. 2 clean sheets from 10 outings suggests some defensive organisation. This season is still relatively young for Charlton, so this record blends games from this season and last.

Charlton's form when playing away from home: 1W 4D 5L across 10 road games this term (0.70 PPG). Away from home they average 0.90 goals scored and 2.10 conceded per game. Both teams have scored in 70% of their away matches — a high BTTS rate on the road that directly informs this fixture.

The form ledger tips toward Portsmouth. A 1.50 PPG lead over Charlton (1.90 vs 0.40) is a consistent enough margin to carry weight. If the win odds appear compressed, Draw No Bet offers draw insurance at a lower cost than a full switch to Double Chance.

In terms of goals, both squads have been finding the net consistently (using home/away splits) — Portsmouth have seen both teams score in 60% of their games, Charlton in 70%. That combined rate is a strong statistical case for BTTS Yes as a standalone play.

H2H Analysis

The head-to-head record is closely matched — Portsmouth lead 2W to 3W over the last 9 encounters, with 4 draws, though neither side has established a commanding advantage.

The 9 previous meetings have averaged 2.8 goals per game — a neutral rate that provides no strong lean on the goals market from the H2H alone. The most recent clash, on 12 Sep 2026, ended 0–0 with a draw.

The head-to-head offers no strong directional steer in either the result or goals markets. Form, the predictive model and current market pricing should carry more weight than the historical record for this fixture.

Trading

Portsmouth half-time and goal-timing data (60 games, 30 at home): they score before half-time in 77% of fixtures in home games; when goalless at HT, a second-half goal follows 78% of the time; BTTS occurs in 53% of their matches (home games); Over 2.5 goals lands in 47% of games (home games).

Charlton half-time and goal-timing data (60 games, 30 at away): they score before half-time in 47% of fixtures in away games; when goalless at HT, a second-half goal follows 86% of the time; BTTS occurs in 57% of their matches (away games); Over 2.5 goals lands in 43% of games (away games).

BTTS rates are mixed from the trading data — Portsmouth 55% versus Charlton 53%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Portsmouth 45% | Charlton 42%).

Poisson Model

The Poisson distribution model projects Portsmouth 2.10 xG and Charlton 1.09 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 1.088 / defence 1.091 | Charlton attack 0.770 / defence 1.274. League average goals — home 1.514 / away 1.292. Charlton bring a strong defensive rating of 1.274 — this is suppressing Portsmouth's projected output below what their attack strength alone would suggest. Data: 60 Portsmouth games / 60 Charlton games used (CurrentSeason).

Result probabilities: Portsmouth 61% | Draw 21% | Charlton 19%. Fair-value odds: Portsmouth 1.64 | Draw 4.76 | Charlton 5.26. The model has a clear lean to Portsmouth (61%) — a 42pp gap over the next-most-likely outcome reflects a meaningful statistical advantage.

Goals markets: Over 2.5 probability 62% | BTTS probability 58% | Total xG 3.19. Over 2.5 holds a meaningful probability edge at 62% — the 3.19 total xG provides moderate support, though the model is not projecting a high-scoring game. BTTS probability of 58% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Verdict

The Poisson model's primary lean is Portsmouth at 61% — clear model lean. Current-season form corroborates the Poisson lean — partial multi-source support. Draw No Bet is worth pricing alongside the outright: 21% draw probability makes the stalemate a live outcome even at this conviction level.

On the goals line, Poisson's 3.19 combined xG gives a 62% probability to Over 2.5 — strong, supported by form averaging 3.0 goals per game and H2H averaging 2.8 goals per meeting.

The Poisson model's BTTS call is Yes at 58%. Form rates corroborate: Portsmouth 60% | Charlton 70% BTTS from recent games.
