Rayo Vallecano1-1Deportivo Alavés

Rayo Vallecano host Deportivo Alavés in the second round of the 2026-27 La Liga season. Both sides played their opening match on August 15, so the current season's table is too small to draw conclusions; the figures here come from the 2025-26 campaign. The most important numbers point to Rayo: they have won all four recorded meetings against Alavés, and the Poisson model gives them a 46.1% win probability, with a 1-0 result as the most likely exact scoreline.

The model projects a low-scoring, tight match, with roughly 2.3 total goals and a 45.4% chance that both teams score. Rayo's home defence was a strength last season, while Alavés's away record was a clear weakness. That combination explains why the hosts are favored, though the draw probability remains significant at 27.6%.

Rayo Vallecano finished eighth last season with 50 points from 38 matches, winning 12, drawing 14 and losing 12. They scored 41 goals (1.08 per game) and conceded 44 (1.16), a profile shaped by an attack ranked 17th and a defence ranked 4th in the division. Their recent form in the 2025-26 table was WWDDW.

Their most recent five matches, most recent first, read LLWWD, with an average of 1.4 goals scored and 1.2 conceded per game. They last played on August 15 and have had five days to rest. The defensive stability that defined their 2025-26 season at home is evident, though the small recent sample offers a more mixed picture.

Deportivo Alavés were 14th in 2025-26, taking 43 points from 38 games with an 11-10-17 record. They scored 44 goals (1.16 per game) and conceded 56 (1.47), ranking 14th in attack and 13th in defence. Their recent form in the 2025-26 table was LWWDL.

Across their last five matches, the record reads DLWWD (most recent first), with a notably stingy defensive line: 0.8 goals scored and 0.6 conceded per game in that stretch. They also played on August 15 and have had five days between matches.

Head-to-head, the record is completely one-sided. The four meetings on file have all been won by Rayo Vallecano, who hold a 6-1 aggregate goal advantage. Three of the four games produced two goals or fewer.

At Vallecas, Rayo won 1-0 in October 2024 and again in October 2025. In the two meetings at Alavés, Rayo won 2-0 in March 2025 and 2-1 in May 2026. These results, while a small sample, are consistent with the model's expectation of a narrow home win.

Rayo's defensive strength is amplified at home. In their last 20 matches at Vallecas, they won seven, drew 11 and lost just two, averaging 1.2 goals scored and only 0.75 conceded per game. Their home win rate of 35% is above their overall win rate of 31.6%.

Alavés's away form is much weaker. Over their last 20 away matches, they have five wins, four draws and 11 losses, scoring exactly one goal per game and conceding 1.55. That 25% away win rate is below their overall 28.9%. The combination of Rayo's home solidity and Alavés's road struggles is central to the model's assessment.

Both teams enter with identical rest periods — five days since their respective matches on August 15 — so there is no meaningful freshness edge. The schedule strength is similar: Rayo's recent opponents have averaged a rank of 9.8 across four fixtures, while Alavés's have averaged 10.2 across five. That suggests both have been tested to a similar degree, though Alavés's sample includes one extra match.

The larger caveat is the sample itself. With only one round of the new season played, the underlying strength ratings are drawn from the full 2025-26 campaign. No promotion adjustment is applied to these estimates, so they are based directly on last season's performance levels. That makes projections reliable in general, but early-season form can deviate from those baselines.

The model, running with high confidence, gives Rayo a 46.1% chance of winning, a 27.6% chance of a draw and a 26.2% chance of an Alavés victory. The projected scoreline is 1-0, built from expected goals of 1.35 for Rayo and 0.95 for Alavés. The most likely exact scorelines are 1-0 (13.6%), 1-1 (12.8%) and 0-0 (10%).

The total-goals expectation is about 2.3, with a 66.9% probability of at least two goals, 40.4% of at least three and 20.1% of at least four. Both teams are projected to score in 45.4% of scenarios. On the winning-margin side, a one-goal home win is projected in 24.3% of scenarios, a draw in 27.6%, a one-goal away win in 17%, a home win by two or more in 21.8%, and an away win by two or more in 9.2%. The picture is of a close match in which Rayo's greater overall likelihood of winning is spread across narrow margins.

The evidence points to a narrow Rayo Vallecano home win. Their perfect head-to-head record, strong home defensive numbers from last season, and the model's 46.1% win probability all align. Alavés's poor away record makes them the underdog, though their recent defensive form — 0.6 goals conceded per game over their last five matches — offers a plausible path to a low-scoring draw. The projected 1-0 scoreline suggests a game that could be decided by a single goal.

If Rayo reproduce the defensive form that made them the fourth-best defence in La Liga, that margin should hold. The main risk to the forecast is Alavés's ability to keep the game goalless or produce one away goal. With the draw at 27.6% and an away win at 26.2%, the model is not treating this as a foregone conclusion, but the balance of data clearly favors the hosts.
