H2H Record

Real Betis have tended to come out on top in this fixture, winning 4 of the last 10 encounters against Rayo Vallecano's 1 victories.

Poisson Model

The Poisson distribution model projects Rayo Vallecano 1.61 xG and Real Betis 1.09 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: Rayo Vallecano attack 0.967 / defence 0.903 | Real Betis attack 1.074 / defence 1.033. League average goals — home 1.617 / away 1.119. Data: 38 Rayo Vallecano games / 38 Real Betis games used (PrevSeason). Note: current-season sample is too small — prior-season data is carrying the calculation. Model confidence is reduced; treat probabilities as directional rather than precise.

Result probabilities: Rayo Vallecano 50% | Draw 25% | Real Betis 26%. Fair-value odds: Rayo Vallecano 2.00 | Draw 4.00 | Real Betis 3.85. Rayo Vallecano hold a narrow Poisson edge at 50% — the draw (25%) is close enough to merit draw-inclusive market consideration.

Goals markets: Over 2.5 probability 51% | BTTS probability 53% | Total xG 2.70. Over/Under 2.5 is close to a coin-flip at 51%/49% — the total xG of 2.70 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 Rayo Vallecano at 50% — moderate model lean. With a 25% draw probability, Draw No Bet on Rayo Vallecano offers a more defensible entry point than the straight win.

The Poisson model projects 2.70 xG in total — Over 2.5 at 51% — reasonable confidence, supported by form averaging 2.8 goals per game.

On the BTTS market, Poisson puts 53% on Yes. Form rates corroborate: Rayo Vallecano 50% | Real Betis 80% BTTS from recent games.

The Poisson model is drawing on PrevSeason data (38 games minimum) — early-season projections carry additional uncertainty. Weight the live form and odds signals accordingly.
