✍️ Match Preview

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): 1W 5D 4L across 10 La Liga fixtures this term — 0.80 PPG. Last five: D L L W D. They are averaging 1.30 goals per game and conceding 1.80 — 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 4W 4D 2L at Anoeta — 1.60 PPG. They are averaging 2.10 goals per home game — a prolific scoring rate in front of their own fans. Both teams have scored in 70% of their home games — an outstanding BTTS rate that is a key data point for this fixture. Their home PPG of 1.60 is noticeably stronger than their overall 0.80 — Real Sociedad are significantly better at Anoeta than their overall form suggests.

Alaves have collected 1.70 PPG across 10 La Liga outings this season: 5W 2D 3L. Last five: W L W D W. Their scoring rate of 1.40 per game is modest, conceding 1.10 — 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 60% of their games — a noteworthy BTTS rate that supports the Yes market. 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: 3W 4D 3L across 10 road games this term (1.30 PPG). Away from home they average 1.60 goals scored and 1.70 conceded per game. Both teams have scored in 80% of their away matches — a high BTTS rate on the road that directly informs this fixture.

On a straight form reading, Alaves are the stronger side — 0.90 PPG clear of the hosts (1.70 vs 0.80). Backing them with draw insurance is the conservative play if the outright away price appears short.

The BTTS picture is exceptionally clear (using home/away splits) — Real Sociedad register both teams scoring in 70% of relevant games, Alaves in 80%. Both sides above 70% makes BTTS Yes one of the strongest standalone angles in this fixture.

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 (41 games, 20 at home): they score before half-time in 75% of fixtures in home games; when goalless at HT, a second-half goal follows 88% of the time; BTTS occurs in 75% of their matches (home games); Over 2.5 goals lands in 70% of games (home games); Over 3.5 in 42%.

Alaves half-time and goal-timing data (41 games, 20 at away): they score before half-time in 55% of fixtures in away games; when goalless at HT, a second-half goal follows 93% of the time; two or more arrive in the second half on 67% of those occasions; BTTS occurs in 55% of their matches (away games); Over 2.5 goals lands in 40% of games (away games).

From a combined perspective, both sides have high BTTS rates — Real Sociedad 76% and Alaves 61% — 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 58% | Alaves 49%).

Poisson Model

The Poisson distribution model projects Real Sociedad 1.53 xG and Alaves 1.15 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 0.999 / defence 1.010 | Alaves attack 1.032 / defence 0.968. League average goals — home 1.585 / away 1.104. Data: 42 Real Sociedad games / 41 Alaves games used (CurrentSeason).

Result probabilities: Real Sociedad 46% | Draw 25% | Alaves 29%. Fair-value odds: Real Sociedad 2.17 | Draw 4.00 | Alaves 3.45. Real Sociedad hold a narrow Poisson edge at 46% — the draw (25%) is close enough to merit draw-inclusive market consideration.

Goals markets: Over 2.5 probability 50% | BTTS probability 54% | Total xG 2.68. Over/Under 2.5 is close to a coin-flip at 50%/50% — the total xG of 2.68 sits near the 2.5 margin; this is a low-edge market from a Poisson standpoint. BTTS probability of 54% 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 46% — moderate 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 25% warrants consideration of Double Chance or Draw No Bet on Real Sociedad if the outright odds are short. The opposing side holds a 29% win probability per the model — this is not a banker and should be staked accordingly.

Poisson projects 2.68 total expected goals, pointing to Over 2.5 at 50% probability — reasonable conviction, supported by form averaging 3.5 goals per game.

On the BTTS market, Poisson puts 54% on Yes. Form rates corroborate: Real Sociedad 70% | Alaves 80% BTTS from recent games.
