Full Analysis

Brunton Park plays host to Carlisle versus Portsmouth in League One (matchday 32). Kick-off: Saturday 10 February 2024 at 15:00 UK time.

Form & Momentum

Carlisle have collected 0.50 PPG across their last 10 games: 1W 2D 7L. Last five: L L L L L. They are averaging 1.10 goals per game and conceding 2.10 — a modest attacking output that tempers optimism on the Over 2.5 market. However, 2.10 goals conceded per game is a concern — opposing attacks have exploited them regularly. Both teams have scored in 80% of their matches — an extremely high rate that makes BTTS Yes a well-supported standalone angle from their form alone.

At home, Carlisle have gone 2W 3D 5L in their last 10 home games (0.90 PPG). At home they are averaging 1.00 goals scored and 1.60 conceded per game. Both teams have scored in 70% of their home games — an outstanding BTTS rate that is a key data point for this fixture.

Portsmouth's record over their last 10 games: 4W 3D 3L (1.50 PPG). Last five: L W W D W. Their scoring rate of 1.30 per game is modest, conceding 1.20 — not a side to back heavily on the Over 2.5 from their form alone. 3 clean sheets from 10 outings (30%). Both teams have scored in 60% of their games — a noteworthy BTTS rate that supports the Yes market.

Portsmouth's form when playing away from home: 6W 2D 2L across their last 10 road games (2.00 PPG). Away from home they average 1.70 goals scored and 0.80 conceded per game. 6 away clean sheets from their last 10 away games (60%) — they are hard to break down on the road. Their away PPG of 2.00 exceeds their overall 1.50 — they actually perform better on the road than their aggregate form implies.

The travelling side arrive in better shape. Portsmouth are 1.00 PPG clear of Carlisle over their recent games (1.50 vs 0.50). Backing the visitors outright or on Draw No Bet are both valid approaches where the price allows.

H2H History

The head-to-head record is closely matched — across the 1 H2H match in our data, Portsmouth edge it 1 wins to 0, with 0 draws. Neither side has a commanding advantage. With only 1 H2H match to go on, treat this as a light input.

Scoring has been limited in the 1 H2H match in our data, averaging 1.0 goals per game, which makes Under 2.5 the head-to-head-backed angle in the goals market. The most recent of those, on 21 Oct 2023, ended Carlisle 0–1 Portsmouth — a Portsmouth win.

With a balanced win record and just 1.0 goals per game, the H2H data points toward a tight, low-scoring contest — Under 2.5 is the stronger head-to-head angle regardless of which side wins.

Trading & In-Play

Carlisle — key trading statistics (last 77 games, 39 of them at home): at least one goal arrives before half-time in 72% of their matches in home games; when goalless at HT, a second-half goal follows 67% of the time; of the 26 games they trailed at half-time, they recovered to draw or win 31%; BTTS occurs in 51% of their matches (home games); Over 2.5 goals lands in 38% of games (home games); they fail to score in 34% of games.

Portsmouth — key trading statistics (last 77 games, 39 of them away): at least one goal arrives before half-time in 69% of their matches in away games; when goalless at HT, a second-half goal follows 64% of the time; of the 17 games they trailed at half-time, they recovered to draw or win 41%; BTTS occurs in 46% of their matches (away games); Over 2.5 goals lands in 44% of games (away games); they keep a clean sheet 40% of the time.

BTTS rates are mixed from the trading data — Carlisle 51% versus Portsmouth 51%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Carlisle 42% | Portsmouth 46%).

Poisson Model

The Poisson distribution model projects Carlisle 0.76 xG and Portsmouth 1.94 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: Carlisle attack 0.767 / defence 1.415 | Portsmouth attack 1.173 / defence 0.761. League average goals — home 1.302 / away 1.169. Carlisle's attack rating of 0.767 is below the league average, which holds their xG down at 0.76. Portsmouth bring a tight defence (rating 0.761, below 1 = concedes less than average) — this is pulling Carlisle's projected output down. Carlisle's defence rating of 1.415 (above 1 = concedes more than average) is pushing Portsmouth's projected output up. Data: built from Carlisle's last 30 games and Portsmouth's last 77.

Result probabilities: Carlisle 14% | Draw 21% | Portsmouth 65%. Fair-value odds: Carlisle 7.22 | Draw 4.78 | Portsmouth 1.53. The model has a clear lean to Portsmouth (65%) — a 44pp gap over the next-most-likely outcome reflects a meaningful statistical advantage.

Goals markets: Over 2.5 probability 51% | BTTS Yes probability 46% | Total xG 2.70. Over/Under 2.5 is close to a coin-flip at 51%/49% — the total xG of 2.70 sits near the 2.5 margin; this is a low-edge market from a Poisson standpoint. BTTS No at 54% is only a slight lean — the model gives both sides a fair chance of scoring, so No isn't a clear standalone call.

Verdict

The Poisson model's primary lean is Portsmouth at 65% — clear model lean. Recent 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.

The Poisson model projects 2.70 xG in total — Over 2.5 at 51% — a Poisson-only call with no corroboration from form or H2H.

Poisson assigns a 54% probability to BTTS No based on the attack/defence strength model. Form rates are neutral — both teams scored in: Carlisle 70% (last 10 home games) | Portsmouth 40% (last 10 away games).
