Full Analysis

Anoeta plays host to Real Sociedad versus Alaves in La Liga, Regular Season - 29. Kick-off: Sunday 21 March 2027 at 16:00 UTC.

Form

Real Sociedad (all games): 3W 3D 4L across 10 La Liga fixtures this term — 1.20 PPG. Last five: W D W L W. They are averaging 1.40 goals per game and conceding 1.90 — a modest attacking output that tempers optimism on the Over 2.5 market. 1 clean sheet from 10 outings provides some defensive foundation. Both teams have scored in 70% of their games — a high BTTS rate that carries real weight in the goals markets. Real Sociedad have played only a handful of La Liga games so far this season, so this record also draws on matches from last season.

In front of their own supporters this season, Real Sociedad have posted 3W 4D 3L at Anoeta — 1.30 PPG. At home they are averaging 1.80 goals scored and 1.80 conceded per game. BTTS has landed in 60% of their home matches — a rate that supports the Yes angle in this fixture.

Alaves have collected 1.70 PPG across 10 La Liga outings this season: 5W 2D 3L. Last five: W W L L D. Their scoring rate of 1.40 per game is modest, conceding 0.80 — not a side to back heavily on the Over 2.5 from their form alone. Defensively, 0.80 goals conceded per game is elite-level — a side this difficult to score against is a real threat to Over 2.5 and BTTS Yes. 5 clean sheets from 10 games (50%) is an exceptional defensive record — they are keeping clean sheets more often than not. Alaves have played only a handful of La Liga games so far this season, so this record also draws on matches from last season.

Alaves's form when playing away from home: 2W 4D 4L across 10 road games this term (1.00 PPG). Away from home they average 1.40 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. Their away PPG of 1.00 is notably below their overall 1.70 — form away from home has been a clear weakness this season.

On a straight form reading, Alaves are the stronger side — 0.50 PPG clear of the hosts (1.70 vs 1.20). Backing them with draw insurance is the conservative play if the outright away price appears short.

In terms of goals, both squads have been finding the net consistently (using home/away splits) — 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

Form and model data should carry more weight here — the historical record is too balanced to provide a directional steer. From 8 meetings: Real Sociedad 2W, Alaves 3W, 3D.

The 8 previous meetings have averaged 2.1 goals per game — a neutral rate that provides no strong lean on the goals market from the H2H alone. The most recent clash, on 11 Apr 2026, ended 3–3 with a draw.

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

Trading

Real Sociedad half-time and goal-timing data (45 games, 22 at home): they score before half-time in 73% of fixtures in home games; when goalless at HT, a second-half goal follows 90% of the time; two or more arrive in the second half on 50% of those occasions; BTTS occurs in 73% of their matches (home games); Over 2.5 goals lands in 73% of games (home games); Over 3.5 in 42%.

Alaves half-time and goal-timing data (45 games, 22 at away): they score before half-time in 54% of fixtures in away games; when goalless at HT, a second-half goal follows 88% of the time; two or more arrive in the second half on 59% of those occasions; BTTS occurs in 54% of their matches (away games); Over 2.5 goals lands in 41% of games (away games).

From a combined perspective, both sides have high BTTS rates — Real Sociedad 76% and Alaves 60% — 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 60% | Alaves 49%).

Poisson Model

The Poisson distribution model projects Real Sociedad 1.19 xG and Alaves 1.17 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 0.861 / defence 1.124 | Alaves attack 0.832 / defence 0.853. League average goals — home 1.621 / away 1.250. Data: 45 Real Sociedad games / 45 Alaves games used (CurrentSeason).

Result probabilities: Real Sociedad 36% | Draw 30% | Alaves 35%. Fair-value odds: Real Sociedad 2.78 | Draw 3.33 | Alaves 2.86. This is a low-confidence result — no outcome exceeds 45%. The draw at 30% is a primary outcome, not an afterthought.

Goals markets: Over 2.5 probability 42% | BTTS probability 49% | 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 49% is moderate — 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 36% — marginal model lean. Note a divergence: in-form Alaves (1.70 PPG) cuts against the Poisson lean — consider the strength-adjusted model over surface-level form results. Draw probability of 30% warrants consideration of Double Chance or Draw No Bet on Real Sociedad if the outright odds are short. The opposing side holds a 35% win probability per the model — this is not a banker and should be staked accordingly.

Poisson projects 2.36 total expected goals, pointing to Under 2.5 at 42% probability — Poisson-only — limited corroboration conviction — though form averaging only 3.4 goals per game points in the other direction.

On the BTTS market, Poisson puts 49% on No. This conflicts with form data: Real Sociedad 60% | Alaves 70% from recent games — a notable divergence.

The outsider holds a 35% win probability per the model — this is not a banker and should not be treated as one. Proportionate stakes are appropriate given the genuine contest the data projects.
