La Liga Best Bets, Predictions & Expert Picks Thursday, August 20, 2026

Analyse

Alaves is coming off a massive opening week where they looked like world beaters. They put up three goals and didn't allow a single one. That is the definition of a dominant start. Now they travel to face a Rayo Vallecano side that's already stumbling. Rayo lost their first match and gave up two goals in the process. The model sees a huge discrepancy here that the bookies are missing. We are looking at a 20.3 percent edge on Alaves at plus 0.25. That is a massive number for a league like La Liga. The books have Rayo as a slight favorite because they are at home, but the data does not support that. Alaves currently ranks first in the league in both offensive and defensive efficiency. Rayo is sitting at seventh in both categories. It is not even close. And the confidence level is at 90 percent. That tells you everything you need to know. Alaves is playing with a ton of momentum. They are scoring three goals per game while Rayo is only managing one. If Alaves keeps that clean sheet momentum going, Rayo will struggle to even get on the board. Getting a quarter goal of insurance on the better team is a gift. I expect Alaves to control the pace and potentially walk away with all three points. But even a draw gets us paid. It is the smartest play on the board today.

À contre-courant du public

The public usually defaults to the home team in these matchups. They think Rayo Vallecano will bounce back just because they are playing in front of their own fans. But the numbers show Alaves is simply the superior squad on both ends of the pitch.
