Robbo's Verdict

Strong
Rayo Vallecano to win Strong lean Strong · Clear advantage

The model gives Vallecano a 62.7% win probability, reflecting their superior expected goals and Osasuna’s low scoring rate.

Show the maths
Osasuna’s expected goals sit at 0.3 while Vallecano’s stand at 1.3, creating a full‑goal gap that the model translates into a 62.7% win chance for Vallecano. The draw probability is 28.9% and Osasuna’s win chance only 8.5%, confirming the one‑sided nature of the matchup. The top predicted scorelines (0‑1 at 26.2% and 0‑2 at 17.1%) reinforce the likelihood of Vallecano scoring while keeping a clean sheet.
Pick 2 · Both Teams to Score
Both Teams to Score — No (one side kept off the scoresheet) 81.1% model probability

With Osasuna averaging 0.3 expected goals and Rayo Vallecano averaging 1.3, the model gives a 81.1% chance at least one side fails to score, ahead of the 18.9% it gives to both teams scoring.

Show the maths
BTTS probability is derived from each side's expected goals (Osasuna 0.3, Rayo Vallecano 1.3) run through the same Poisson goal-expectancy model used for the match result: 18.9% of simulated outcomes have both teams scoring at least once, versus 81.1% where at least one side is shut out.
Pick 3 · Total Goals
Under 2.5 Goals 78.3% model probability

Combined expected goals of 1.6 (Osasuna 0.3 + Rayo Vallecano 1.3) points to a tighter game, with the model giving Under 2.5 Goals a 78.3% chance against 21.7% for Over.

Show the maths
Total goals probability comes from the same Poisson model summing both teams' expected goals (Osasuna 0.3 + Rayo Vallecano 1.3 = 1.6 combined): 21.7% of simulated outcomes finish with 3 or more goals, versus 78.3% finishing with 2 or fewer.
Match Result Model

Our Poisson model, built from each side's real season scoring and conceding rates, has Osasuna at 8.5%, the draw at 28.9%, and Rayo Vallecano at 62.7% to win.

Most Likely Scoreline

The single most likely scoreline in our model is 0-1 at 26.2% — treat any single scoreline price with caution given how spread out the probability distribution is across a low-scoring match.

Form Guide — Last 5

Osasuna

DWWLL

Osasuna’s last five league games show a win over Celta Vigo (2‑1) and a win over Getafe (1‑0), but they were also beaten 2‑5 by Alavés and 0‑2 by Espanyol. Those conceding lapses, combined with a modest scoring output, underline their struggle to produce goals at home, supporting a low‑scoring outcome for this fixture.

Rayo Vallecano

LDLWL

Rayo Vallecano’s recent away results include a 1‑2 loss at Sevilla and a 1‑4 defeat at Real Madrid, yet they secured a 3‑2 home win over Racing Santander. The ability to find the net even on the road, despite conceding heavily, aligns with the model’s expectation of them scoring and keeping the game tight.

Head-to-Head

In the last five meetings, Osasuna have won twice, Vallecano have won twice, and there has been one draw (1‑1 in 2025). The split record means there is no historic edge, leaving the model’s statistical advantage as the decisive factor.
