Market Consistency and ROI
Odds are tightly clustered: Winamax (FR) and Everygame show the lowest ROI (91.5–91.6%), while Betfair and Matchbook peak at 99.4%. Pinnacle sits at 96.8%, a central and reliable position. The 99.9% optimal ROI by combining the three best cotes (2.36 / 3.15 / 3.85) confirms a highly efficient market.

Value on Away Win (Alavés)
Alavés presents the clearest value signal. Betfair, Matchbook, Unibet (SE), and Unibet (NL) offer 3.85, versus Pinnacle's fair odd of 3.74, translating to +3.0% potential value. Coolbet follows closely at 3.80 (+1.6%). This is moderate but tangible value, meaningful for consistent bettors. On the home win (Rayo) and draw, no cote exceeds the fair odd—consensus is maximal.

Sportsbook Comparison
Winamax (FR), LeoVegas, and Everygame apply the most aggressive margins (ROI < 92%). Betfair and Matchbook combine low margin (99.4% ROI) and best raw prices, especially on the away outcome. For bettors optimizing edge, these two platforms merit attention. Pinnacle remains the reliable benchmark but offers no specific advantage versus Betfair here.

Recommendation
Moderate value on Alavés is confirmed: the 3.85 cote at Betfair or Matchbook exceeds Pinnacle's implied probability. If this spread persists, examining this bet via a Value Bet calculator to validate long-term profitability is warranted. The 99.9% optimal ROI reflects a highly competitive market; sourcing best prices via an ROI Tracker remains essential.
