Full Analysis

Estádio Municipal de Rio Maior plays host to Casa Pia versus Rio Ave in Primeira Liga (matchday 34). Kick-off: Saturday 16 May 2026 at 19:00 UK time.

Current Form

Casa Pia's record over their last 10 games: 1W 4D 5L (0.70 PPG). Last five: D L L L W. They are averaging 0.50 goals per game and conceding 1.30 — a modest attacking output that tempers optimism on the Over 2.5 market. 3 clean sheets from 10 outings (30%).

Casa Pia at home: 2W 6D 2L from their last 10 home games — 1.20 PPG on home soil. At home they are averaging 1.10 goals scored and 1.10 conceded per game. BTTS has landed in 60% of their home matches — a rate that supports the Yes angle in this fixture. Their home PPG of 1.20 is noticeably stronger than their overall 0.70 — Casa Pia are significantly better at home than their overall form suggests.

Rio Ave (all games): 4W 3D 3L across their last 10 — 1.50 points per game. Last five: W D L D L. Their scoring rate of 1.10 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.

Rio Ave's form when playing away from home: 4W 1D 5L across their last 10 road games (1.30 PPG). Away from home they average 0.90 goals scored and 1.80 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.

Rio Ave arrive in superior form — a 0.80 PPG advantage (1.50 vs 0.70) that offsets much of the home-ground benefit. The away side are the form pick, with draw protection the sensible way to manage the home-field uncertainty.

Head-to-Head

The head-to-head record is closely matched — across the 7 H2H matches in our data, the wins are level at 2 apiece, with 3 draws. Neither side has a commanding advantage.

The 7 H2H matches in our data averaged 2.4 goals per game — a neutral rate that gives no strong lean on the goals market from the H2H alone. The most recent of those, on 4 Jan 2026, ended Casa Pia 1–3 Rio Ave — a Rio Ave win.

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

Trading

Casa Pia half-time and goal-timing data (last 67 games, 33 of them at home): at least one goal arrives before half-time in 73% of their matches in home games; when goalless at HT, a second-half goal follows 71% of the time; of the 15 games they led at half-time, they failed to win 47%; BTTS occurs in 61% of their matches (home games); Over 2.5 goals lands in 36% of games (home games); they fail to score in 36% of games.

Rio Ave half-time and goal-timing data (last 67 games, 33 of them away): at least one goal arrives before half-time in 70% of their matches in away games; when goalless at HT, a second-half goal follows 80% of the time; two or more arrive in the second half on 67% of those occasions; of the 16 games they led at half-time, they failed to win 50%; BTTS occurs in 46% of their matches (away games); Over 2.5 goals lands in 52% of games (away games); they fail to score in 34% of games.

BTTS rates are mixed from the trading data — Casa Pia 52% versus Rio Ave 54%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Casa Pia 45% | Rio Ave 55%).

Poisson Model

The Poisson distribution model projects Casa Pia 1.10 xG and Rio Ave 1.05 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 0.742 / defence 1.011 | Rio Ave attack 0.915 / defence 1.021. League average goals — home 1.447 / away 1.137. Casa Pia's attack rating of 0.742 is below the league average, which holds their xG down at 1.10. Data: built from Casa Pia's last 67 games and Rio Ave's last 67.

Result probabilities: Casa Pia 36% | Draw 30% | Rio Ave 34%. Fair-value odds: Casa Pia 2.75 | Draw 3.39 | Rio Ave 2.93. This is a low-confidence result — no outcome reaches 45%. The draw at 30% is a primary outcome, not an afterthought.

Goals markets: Over 2.5 probability 36% | BTTS Yes probability 43% | Total xG 2.15. Under 2.5 has a narrow probability edge at 64% — total xG of 2.15 is below the line but not decisively so. BTTS No at 57% 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 Casa Pia at 36% — marginal model lean. Note a divergence: in-form Rio Ave (1.50 PPG) cuts against the Poisson lean — the model adjusts for opposition strength, which raw form results do not. Draw probability of 30% warrants consideration of Double Chance or Draw No Bet on Casa Pia if the outright odds are short. The opposing side holds a 34% win probability per the model — this is not a banker and should be staked accordingly.

Poisson projects 2.15 total expected goals, pointing to Under 2.5 at 64% probability — a Poisson-only call with no corroboration from form or H2H.

On the BTTS market, Poisson puts 57% on No. Form rates corroborate — both teams scored in: Casa Pia 60% (last 10 home games) | Rio Ave 30% (last 10 away games).
