✍️ Match Preview

Full Analysis

Anoeta plays host to Real Sociedad versus Alaves in La Liga (matchday 29). Kick-off: Sunday 21 March 2027 at 16:00 UK time.

Form

Real Sociedad (all games): 7W 1D 2L across their last 10 — 2.20 PPG. Last five: W W W L W. They are averaging 2.00 goals per game — a high-scoring output that makes them a genuine attacking threat in any fixture. 2 clean sheets from 10 outings (20%). Both teams have scored in 70% of their games — a high BTTS rate that carries real weight in the goals markets.

In front of their own supporters, Real Sociedad have posted 4W 3D 3L from their last 10 home games — 1.50 PPG. At home they are averaging 1.60 goals scored and 1.70 conceded per game. BTTS has landed in 60% of their home matches — a rate that supports the Yes angle in this fixture. Somewhat surprisingly, their home PPG of 1.50 lags behind their overall 2.20 — home advantage has not translated into better results recently.

Alaves have collected 0.90 PPG across their last 10 games: 2W 3D 5L. Last five: L L D L D. Their scoring rate of 1.10 per game is modest, conceding 1.60 — 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.

Alaves's form when playing away from home: 1W 5D 4L across their last 10 road games (0.80 PPG). Away from home they average 1.00 goals scored and 1.70 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.

The points-per-game gap of 1.30 in Real Sociedad's favour (2.20 vs 0.90) is a statistically meaningful difference. The hosts are the form pick here, with draw protection the sensible hedge given the away side's competitiveness.

In terms of goals, both squads have been finding the net consistently (from Real Sociedad's last 10 home games and Alaves's last 10 away games) — Real Sociedad have seen both teams score in 60% of their games, Alaves in 70%. That combined rate is a strong statistical case for BTTS Yes as a standalone play.

H2H History

The head-to-head record is closely matched — across the 8 H2H matches in our data, Alaves edge it 3 wins to 2, with 3 draws. Neither side has a commanding advantage.

The 8 H2H matches in our data averaged 2.1 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 11 Apr 2026, ended Real Sociedad 3–3 Alaves — 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

Real Sociedad half-time and goal-timing data (last 50 games, 25 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 91% of the time; of the 18 games they led at half-time, they failed to win 28%; of the 13 games they trailed at half-time, they recovered to draw or win 31%; BTTS occurs in 72% of their matches (home games); Over 2.5 goals lands in 72% of games (home games); Over 3.5 in 42%.

Alaves half-time and goal-timing data (last 50 games, 25 of them away): at least one goal arrives before half-time in 52% of their matches in away games; when goalless at HT, a second-half goal follows 84% of the time; two or more arrive in the second half on 58% of those occasions; of the 12 games they led at half-time, they failed to win 33%; of the 11 games they trailed at half-time, they recovered to draw or win 36%; BTTS occurs in 56% of their matches (away games); Over 2.5 goals lands in 44% of games (away games).

From a combined perspective, both sides have high BTTS rates — Real Sociedad 76% and Alaves 62% — which reinforces the BTTS Yes angle from in-play data. The over/under 2.5 picture is inconclusive from the in-play data (Real Sociedad 62% | Alaves 50%). There is an in-play dynamic worth noting: Real Sociedad surrender their half-time lead 28% of the time, while Alaves have come from behind at the break to draw or win in 36% of cases — a combination that makes laying the hosts at HT a potential angle. Note also that Alaves surrender HT leads in 33% of cases while Real Sociedad recover from half-time deficits to draw or win 31% of the time — a dynamic that could influence in-play positioning.

Poisson Model

The Poisson distribution model projects Real Sociedad 1.73 xG and Alaves 1.04 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: Real Sociedad attack 1.024 / defence 1.071 | Alaves attack 0.795 / defence 1.106. League average goals — home 1.524 / away 1.218. Alaves's attack rating of 0.795 is below the league average, which holds their xG down at 1.04. Data: built from Real Sociedad's last 50 games and Alaves's last 50.

Result probabilities: Real Sociedad 52% | Draw 27% | Alaves 21%. Fair-value odds: Real Sociedad 1.93 | Draw 3.66 | Alaves 4.77. Real Sociedad hold a narrow Poisson edge at 52% — the draw (27%) is close enough to merit draw-inclusive market consideration.

Goals markets: Over 2.5 probability 52% | BTTS Yes probability 55% | Total xG 2.76. Over/Under 2.5 is close to a coin-flip at 52%/48% — the total xG of 2.76 sits near the 2.5 margin; this is a low-edge market from a Poisson standpoint. BTTS Yes at 55% is only a slight lean — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Final Verdict

Poisson rates Real Sociedad as the most likely outcome at 52% — moderate model lean. Recent form corroborates the Poisson lean — partial multi-source support. Draw probability of 27% warrants consideration of Double Chance or Draw No Bet on Real Sociedad if the outright odds are short.

Poisson projects 2.76 total expected goals, pointing to Over 2.5 at 52% probability — reasonable conviction, supported by recent form (Real Sociedad's last 10 home games and Alaves's last 10 away games) averaging 3.0 goals per game.

On the BTTS market, Poisson puts 55% on Yes. Form rates corroborate — both teams scored in: Real Sociedad 60% (last 10 home games) | Alaves 70% (last 10 away games).
