Fixture Analysis
It is a Primeira Liga clash, Regular Season - 14 as Casa Pia welcome Nacional to . Kick-off is set for Sunday 13 December 2026 at 16:00 UTC.
Form Guide
Casa Pia — All Games: 2W 3D 5L from 10 Primeira Liga outings this season, averaging 0.90 points per game. Last five: L L L L D. They are averaging 0.40 goals per game and conceding 1.30 — a modest attacking output that tempers optimism on the Over 2.5 market. 4 clean sheets in 10 games (40%) reflects a solid defensive base. Both teams have scored in only 10% of their games — a low BTTS rate that suggests clean sheets are a regular occurrence. Casa Pia have played only a handful of Primeira Liga games so far this season, so this record also draws on matches from last season.
In front of their own supporters this season, Casa Pia have posted 2W 4D 4L at — 1.00 PPG. At home they are averaging 0.80 goals scored and 1.50 conceded per game.
Across all Primeira Liga games this season, Nacional have recorded 4W 1D 5L from 10 outings — 1.30 PPG. Last five: D W L L L. Their scoring rate of 1.20 per game is modest, conceding 1.20 — not a side to back heavily on the Over 2.5 from their form alone. 4 clean sheets in 10 outings (40%) underlines their defensive solidity. Both teams have scored in just 30% of their games, reflecting a regular tendency to keep or record clean sheets. Nacional have played only a handful of Primeira Liga games so far this season, so this record also draws on matches from last season.
When travelling in Primeira Liga this season, Nacional have posted 1W 2D 7L from 10 away outings — 0.50 PPG. Away from home they average 0.60 goals scored and 1.60 conceded per game. Away from home, both teams have scored in only 30% of games — a low rate that backs BTTS No when they travel. Their away PPG of 0.50 is notably below their overall 1.30 — form away from home has been a clear weakness this season.
There is minimal separation in the form figures — Casa Pia at 0.90 PPG versus Nacional's 1.30. The form guide is not providing a strong directional steer; the model and market data will carry more weight in the final assessment.
H2H Record
There is little to separate the sides historically. From 4 previous meetings, Casa Pia have won 1, Nacional 2, with 1 draws — a balanced ledger that offers no obvious directional steer on its own.
The last 4 meetings have been tight affairs, averaging just 1.8 goals per game. That low-scoring pattern is a meaningful historical input for the Under 2.5 market. The most recent clash, on 8 Feb 2026, ended 0–0 with a draw.
With a balanced win record and just 1.8 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.
Trading Patterns
Casa Pia in-play and half-time data (39 games, 19 at home): they score before half-time in 68% of fixtures in home games; when goalless at HT, a second-half goal follows 57% of the time; BTTS occurs in 53% of their matches (home games); Over 2.5 goals lands in 32% of games (home games); they fail to score in 51% of games.
Nacional in-play and half-time data (39 games, 19 at away): they score before half-time in 74% of fixtures in away games; when goalless at HT, a second-half goal follows 92% of the time; two or more arrive in the second half on 62% of those occasions; BTTS occurs in 42% of their matches (away games); Over 2.5 goals lands in 32% of games (away games); they fail to score in 33% of games.
BTTS rates are mixed from the trading data — Casa Pia 41% versus Nacional 46%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Casa Pia 41% | Nacional 41%).
Poisson Model
The Poisson distribution model projects Casa Pia 0.93 xG and Nacional 1.43 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: Casa Pia attack 0.688 / defence 1.414 | Nacional attack 0.804 / defence 1.028. League average goals — home 1.317 / away 1.253. Casa Pia's attack strength of 0.688 is below the league average — the 0.93 xG projection reflects a team that scores at a discount to the division norm. Data: 39 Casa Pia games / 39 Nacional games used (CurrentSeason).
Result probabilities: Casa Pia 25% | Draw 27% | Nacional 48%. Fair-value odds: Casa Pia 4.00 | Draw 3.70 | Nacional 2.08. Nacional hold a narrow Poisson edge at 48% — the draw (27%) is close enough to merit draw-inclusive market consideration.
Goals markets: Over 2.5 probability 42% | BTTS probability 46% | Total xG 2.36. Under 2.5 has a narrow probability edge at 58% — total xG of 2.36 is below the line but not decisively so. BTTS probability of 46% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.
Analysis Verdict
On the Poisson output, Nacional are the pick at 48% — moderate model lean. With a 27% draw probability, Draw No Bet on Nacional offers a more defensible entry point than the straight win.
Poisson projects 2.36 total expected goals, pointing to Under 2.5 at 42% probability — reasonable conviction, supported by H2H averaging 1.8 goals per meeting.
The Poisson model's BTTS call is No at 46%. Form rates corroborate: Casa Pia 40% | Nacional 30% BTTS from recent games.
