Full Analysis

San Mamés plays host to Athletic Club versus Osasuna in La Liga (matchday 33). Kick-off: Tuesday 21 April 2026 at 19:00 UK time.

Form & Momentum

Athletic Club have collected 1.40 PPG across their last 10 games: 4W 2D 4L. Last five: L L W L L. They are averaging 1.30 goals per game and conceding 1.50 — a modest attacking output that tempers optimism on the Over 2.5 market. Both teams have scored in 70% of their games — a high BTTS rate that carries real weight in the goals markets.

At home, Athletic Club have gone 5W 1D 4L in their last 10 home games (1.60 PPG). At home they are averaging 1.30 goals scored and 1.30 conceded per game. BTTS has landed in 60% of their home matches — a rate that supports the Yes angle in this fixture.

Osasuna's record over their last 10 games: 3W 5D 2L (1.40 PPG). Last five: D L W D D. Their scoring rate of 1.30 per game is modest, conceding 1.30 — not a side to back heavily on the Over 2.5 from their form alone. 2 clean sheets from 10 outings (20%). Both teams have scored in 70% of their games — a noteworthy BTTS rate that supports the Yes market.

On the road, Osasuna have gone 2W 3D 5L in their last 10 away fixtures (0.90 PPG). Away from home they average 1.00 goals scored and 1.40 conceded per game.

A near-identical PPG reading — 1.40 for Athletic Club, 1.40 for Osasuna — means the form record is uninstructive on result selection. The goals and market sections will carry greater evidential weight.

H2H Analysis

The head-to-head record is closely matched — across the 8 H2H matches in our data, Athletic Club edge it 3 wins to 1, with 4 draws. Neither side has a commanding advantage.

The 8 H2H matches in our data averaged 1.9 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 3 Jan 2026, ended Athletic Club 1–1 Osasuna — a draw.

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 Data

Athletic Club goal-timing and half-time pattern breakdown (last 69 games, 35 of them at home): at least one goal arrives before half-time in 63% of their matches in home games; when goalless at HT, a second-half goal follows 80% of the time; of the 14 games they trailed at half-time, they recovered to draw or win 57%; BTTS occurs in 51% of their matches (home games); Over 2.5 goals lands in 43% of games (home games).

Osasuna goal-timing and half-time pattern breakdown (last 69 games, 35 of them away): at least one goal arrives before half-time in 43% of their matches in away games; when goalless at HT, a second-half goal follows 78% of the time; of the 26 games they led at half-time, they failed to win 38%; of the 14 games they trailed at half-time, they recovered to draw or win 43%; BTTS occurs in 46% of their matches (away games); Over 2.5 goals lands in 34% of games (away games).

BTTS rates are mixed from the trading data — Athletic Club 51% versus Osasuna 58%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Athletic Club 42% | Osasuna 45%). Note also that Osasuna surrender HT leads in 38% of cases while Athletic Club recover from half-time deficits to draw or win 57% of the time — a dynamic that could influence in-play positioning.

Poisson Model

The Poisson distribution model projects Athletic Club 1.31 xG and Osasuna 1.08 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: Athletic Club attack 0.903 / defence 1.079 | Osasuna attack 0.886 / defence 0.937. League average goals — home 1.553 / away 1.124. Data: built from Athletic Club's last 69 games and Osasuna's last 69.

Result probabilities: Athletic Club 42% | Draw 27% | Osasuna 30%. Fair-value odds: Athletic Club 2.38 | Draw 3.64 | Osasuna 3.28. This is a low-confidence result — no outcome reaches 45%. The draw at 27% is a primary outcome, not an afterthought.

Goals markets: Over 2.5 probability 43% | BTTS Yes probability 48% | Total xG 2.39. Under 2.5 has a narrow probability edge at 57% — total xG of 2.39 is below the line but not decisively so. BTTS No at 52% is only a slight lean — the model gives both sides a fair chance of scoring, so No isn't a clear standalone call.

Picks & Verdict

On the Poisson output, Athletic Club are the pick at 42% — marginal model lean. Draw probability of 27% warrants consideration of Double Chance or Draw No Bet on Athletic Club if the outright odds are short. The opposing side holds a 30% win probability per the model — this is not a banker and should be staked accordingly.

On the goals line, Poisson's 2.39 combined xG gives a 57% probability to Under 2.5 — reasonable conviction, supported by the H2H data averaging 1.9 goals per game across 8 H2H matches.

The Poisson model's BTTS call is No at 52%. Form rates are neutral — both teams scored in: Athletic Club 60% (last 10 home games) | Osasuna 50% (last 10 away games).
