✍️ 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 1D 4L from 10 games (1.60 PPG). Last five: D L W L L. They are averaging 1.40 goals per game and conceding 1.50 — a modest attacking output that tempers optimism on the Over 2.5 market. 3 clean sheets 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. Portsmouth have played only a handful of Championship games so far this season, so this record also draws on matches from last season.

In front of their own supporters this season, Portsmouth have posted 2W 2D 6L at Fratton Park — 0.80 PPG. At home they are averaging 0.80 goals scored and 1.30 conceded per game. Somewhat surprisingly, their home PPG of 0.80 lags behind their overall 1.60 — the home advantage has not translated into superior results at Fratton Park this season.

Charlton (all games): 4W 2D 4L across 10 Championship outings this term — 1.40 points per game. Last five: W L W W W. Their scoring rate of 1.30 per game is modest, conceding 1.40 — not a side to back heavily on the Over 2.5 from their form alone. 1 clean sheet from 10 outings suggests some defensive organisation. Both teams have scored in 90% of their matches this season — one of the stronger BTTS rates in the division, making Yes a well-evidenced play. Charlton have played only a handful of Championship games so far this season, so this record also draws on matches from last season.

Charlton's form when playing away from home: 3W 5D 2L across 10 road games this term (1.40 PPG). Away from home they average 1.10 goals scored and 1.30 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.

Both sides are running at similar form levels — 1.60 PPG for Portsmouth against 1.40 for Charlton. There is no clear form edge to exploit here; other signals need to take the lead.

H2H Analysis

The head-to-head record is closely matched — Portsmouth lead 2W to 3W over the last 8 encounters, with 3 draws, though neither side has established a commanding advantage.

Attacking output has been a hallmark of this fixture. At 3.1 goals per game across 8 meetings, the Over 2.5 has a statistically grounded case from the head-to-head record alone. The most recent clash, on 17 Feb 2026, ended 3–1 with Portsmouth winning.

With the win record balanced, the strongest H2H-derived signal is in the goals market. At 3.1 goals per game historically, Over 2.5 is the cleaner angle to extract from the head-to-head data.

Trading

Portsmouth half-time and goal-timing data (49 games, 24 at home): they score before half-time in 71% of fixtures in home games; when goalless at HT, a second-half goal follows 86% of the time; BTTS occurs in 46% of their matches (home games); Over 2.5 goals lands in 38% of games (home games).

Charlton half-time and goal-timing data (49 games, 24 at away): they score before half-time in 42% of fixtures in away games; when goalless at HT, a second-half goal follows 92% of the time; BTTS occurs in 58% of their matches (away games); Over 2.5 goals lands in 38% of games (away games).

BTTS rates are mixed from the trading data — Portsmouth 57% versus Charlton 55%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Portsmouth 47% | Charlton 41%).

Poisson Model

The Poisson distribution model projects Portsmouth 1.06 xG and Charlton 1.47 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 0.791 / defence 1.139 | Charlton attack 0.996 / defence 0.923. League average goals — home 1.454 / away 1.297. Portsmouth's attack strength of 0.791 is below the league average — the 1.06 xG projection reflects a team that scores at a discount to the division norm. Data: 50 Portsmouth games / 49 Charlton games used (CurrentSeason).

Result probabilities: Portsmouth 24% | Draw 32% | Charlton 44%. Fair-value odds: Portsmouth 4.17 | Draw 3.12 | Charlton 2.27. This is a low-confidence result — no outcome exceeds 45%. The draw at 32% is a primary outcome, not an afterthought.

Goals markets: Over 2.5 probability 46% | BTTS probability 53% | Total xG 2.53. Over/Under 2.5 is close to a coin-flip at 46%/54% — the total xG of 2.53 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.

Verdict

The Poisson model's primary lean is Charlton at 44% — marginal model lean. Draw probability of 32% warrants consideration of Double Chance or Draw No Bet on Charlton if the outright odds are short.

On the goals line, Poisson's 2.53 combined xG gives a 46% probability to Under 2.5 — Poisson-only — limited corroboration — though H2H averaging only 3.1 goals per meeting points in the other direction.

The Poisson model's BTTS call is Yes at 53%. Form rates corroborate: Portsmouth 40% | Charlton 70% BTTS from recent games.
