✍️ Match Preview

Analysis & Preview

A La Liga encounter, Regular Season - 18 sees Osasuna travel to Anoeta to take on Real Sociedad. The game is scheduled for Sunday 3 January 2027, 16:00 UTC.

Form Guide

Real Sociedad — All Games: 1W 5D 4L from 10 La Liga outings this season, averaging 0.80 points per game. 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.

At home at Anoeta, Real Sociedad have gone 4W 4D 2L this season (10 games, 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.

Looking at all fixtures this season, Osasuna stand at 3W 1D 6L from 10 La Liga matches — 1.00 PPG. Last five: L L D W W. Their scoring rate of 1.00 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 suggests some defensive organisation. Both teams have scored in 60% of their games — a noteworthy BTTS rate that supports the Yes market. Osasuna have played only a handful of La Liga games so far this season, so this record also draws on matches from last season.

On the road, Osasuna have gone 3W 2D 5L from 10 away fixtures this term (1.10 PPG). Away from home they average 1.20 goals scored and 1.40 conceded per game. BTTS has landed in 60% of their away games — meaningful support for the Yes angle in this specific context.

There is minimal separation in the form figures — Real Sociedad at 0.80 PPG versus Osasuna's 1.00. The form guide is not providing a strong directional steer; the model and market data will carry more weight in the final assessment.

The BTTS market is worth targeting here. Real Sociedad register both teams scoring in 70% of relevant matches, Osasuna in 60% (using home/away splits) — both sides above the 60% threshold gives BTTS Yes firm statistical grounding.

Head to Head

Real Sociedad hold a clear advantage in this fixture, picking up 6 wins from 10 previous encounters compared to 3 for Osasuna, with 1 draws in between.

The 10 previous meetings have averaged 2.3 goals per game — a neutral rate that provides no strong lean on the goals market from the H2H alone. The most recent clash, on 15 Mar 2026, ended 3–1 with Real Sociedad winning.

The historical record gives Real Sociedad a meaningful edge here — 6 wins from 10 meetings is the kind of ledger that should not be discounted when the form picture is inconclusive. Even away from home, the visitors have struggled to impose themselves in this fixture.

In-Play Profile

Real Sociedad in-play tendencies (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%.

Osasuna in-play tendencies (41 games, 20 at away): they score before half-time in 50% of fixtures in away games; when goalless at HT, a second-half goal follows 80% of the time; BTTS occurs in 40% of their matches (away games); Over 2.5 goals lands in 40% of games (away games); they fail to score in 32% of games.

From a combined perspective, both sides have high BTTS rates — Real Sociedad 76% and Osasuna 54% — 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% | Osasuna 49%).

Poisson Model

The Poisson distribution model projects Real Sociedad 1.52 xG and Osasuna 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 | Osasuna attack 1.026 / defence 0.959. League average goals — home 1.585 / away 1.104. Data: 42 Real Sociedad games / 41 Osasuna games used (CurrentSeason).

Result probabilities: Real Sociedad 46% | Draw 26% | Osasuna 29%. Fair-value odds: Real Sociedad 2.17 | Draw 3.85 | Osasuna 3.45. Real Sociedad hold a narrow Poisson edge at 46% — the draw (26%) is close enough to merit draw-inclusive market consideration.

Goals markets: Over 2.5 probability 50% | BTTS probability 53% | Total xG 2.66. Over/Under 2.5 is close to a coin-flip at 50%/50% — the total xG of 2.66 sits near the 2.5 margin; this is a low-edge market from a Poisson standpoint. BTTS probability of 53% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Summary & Verdict

The Poisson model's primary lean is Real Sociedad at 46% — moderate model lean. With a 26% draw probability, Draw No Bet on Real Sociedad offers a more defensible entry point than the straight win. The opposing side holds a 29% win probability per the model — this is not a banker and should be staked accordingly.

The Poisson model projects 2.66 xG in total — Under 2.5 at 50% — Poisson-only — limited corroboration confidence — though form averaging only 3.2 goals per game points in the other direction.

On the BTTS market, Poisson puts 53% on Yes. Form rates corroborate: Real Sociedad 70% | Osasuna 60% BTTS from recent games.
