Full Analysis
Estadio de Vallecas plays host to Rayo Vallecano versus Espanyol in La Liga, Regular Season - 16. Kick-off: Sunday 5 December 2021 at 13:00 UTC.
Current Form
Rayo Vallecano's overall La Liga record this term: 5W 2D 3L from 10 games (1.70 PPG). Last five: W D L W D. Offensively they are averaging 1.50 goals per game, with 1.10 conceded. 2 clean sheets from 10 outings provides some defensive foundation. Both teams have scored in 70% of their games — a high BTTS rate that carries real weight in the goals markets. This season is still relatively young for Rayo Vallecano, so this record blends games from this season and last.
Rayo Vallecano's form when playing at home: 6W 1D 0L across 7 games at Estadio de Vallecas this term (2.71 PPG). They are averaging 2.29 goals per home game — a prolific scoring rate in front of their own fans. 4 clean sheets from 7 home games (57%) — they are an exceptionally hard side to score against at Estadio de Vallecas. Their home PPG of 2.71 is noticeably stronger than their overall 1.70 — Rayo Vallecano are significantly better at Estadio de Vallecas than their overall form suggests.
Espanyol have collected 1.70 PPG across 10 La Liga outings this season: 5W 2D 3L. Last five: D L W L W. Their scoring rate of 1.20 per game is modest, conceding 0.90 — not a side to back heavily on the Over 2.5 from their form alone. 4 clean sheets in 10 outings (40%) underlines their defensive solidity. This season is still relatively young for Espanyol, so this record blends games from this season and last.
Espanyol's form when playing away from home: 0W 3D 4L across 7 road games this term (0.43 PPG). Away from home they average 0.71 goals scored and 1.43 conceded per game. Their away PPG of 0.43 is notably below their overall 1.70 — form away from home has been a clear weakness this season.
Neither side holds a meaningful form edge. The 1.70 vs 1.70 PPG split is negligible — model and market signals should carry more analytical weight for this one.
Trading Data
Rayo Vallecano goal-timing and half-time pattern breakdown (15 games, 7 at home): they score before half-time in 86% of fixtures in home games; when goalless at HT, a second-half goal follows 67% of the time; BTTS occurs in 43% of their matches (home games); Over 2.5 goals lands in 71% of games (home games).
Espanyol goal-timing and half-time pattern breakdown (15 games, 7 at away): they score before half-time in 71% of fixtures in away games; when goalless at HT, a second-half goal follows 60% of the time; BTTS occurs in 43% of their matches (away games); Over 2.5 goals lands in 43% of games (away games); they keep a clean sheet 40% of the time; they fail to score in 33% of games.
BTTS rates are mixed from the trading data — Rayo Vallecano 53% versus Espanyol 40%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Rayo Vallecano 60% | Espanyol 33%).
Poisson Model
The Poisson distribution model projects Rayo Vallecano 1.66 xG and Espanyol 0.69 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 1.285 / defence 0.853 | Espanyol attack 0.701 / defence 1.278. League average goals — home 1.012 / away 1.162. Rayo Vallecano carry an above-average attack strength of 1.285 — their λ of 1.66 reflects genuine attacking quality above the league norm. Espanyol bring a strong defensive rating of 1.278 — this is suppressing Rayo Vallecano's projected output below what their attack strength alone would suggest. Data: 15 Rayo Vallecano games / 15 Espanyol games used (CurrentSeason).
Result probabilities: Rayo Vallecano 60% | Draw 25% | Espanyol 15%. Fair-value odds: Rayo Vallecano 1.67 | Draw 4.00 | Espanyol 6.67. The model has a clear lean to Rayo Vallecano (60%) — a 45pp gap over the next-most-likely outcome reflects a meaningful statistical advantage.
Goals markets: Over 2.5 probability 42% | BTTS probability 41% | Total xG 2.36. Under 2.5 has a narrow probability edge at 58% — total xG of 2.36 is below the line but not decisively so. BTTS probability of 41% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.
Verdict
The Poisson model's primary lean is Rayo Vallecano at 60% — clear model lean. Draw No Bet is worth pricing alongside the outright: 25% draw probability makes the stalemate a live outcome even at this conviction level.
Poisson projects 2.36 total expected goals, pointing to Under 2.5 at 42% probability — Poisson-only — limited corroboration conviction.
On the BTTS market, Poisson puts 41% on No. Form rates corroborate: Rayo Vallecano 43% | Espanyol 43% BTTS from recent games.

📝 Match Report
How It Unfolded
Rayo Vallecano beat Espanyol 1-0 at Estadio de Vallecas, Regular Season - 16, in the La Liga. That is the final score; the rest of this report grades it against what the data forecast beforehand.
The Model vs The Result
The Poisson model went into this projecting Rayo Vallecano 1.66 xG and Espanyol 0.69 xG, a combined 2.36. The scoreboard read 1-0 for 1 actual goal. Both sides finished within a goal of their individual projections, so the scoreline sat close to the model's expected shape. Those figures were built on strength ratings of Rayo Vallecano attack 1.28 / defence 0.85 against Espanyol attack 0.70 / defence 1.28, drawn from 15/15 games (CurrentSeason).
On the result, the model split it Rayo Vallecano 60% | Draw 25% | Espanyol 15%, with Rayo Vallecano to win its most likely call at 60%. The scoreboard confirmed the model's leading pick.
Goals & Markets
The model rated Over 2.5 goals at 42%. The game delivered 1, so it stayed under — the model's lean was correct. Over 1.5 had been 69% and missed. On both teams to score, the model sat at 41% and the match did not — another call in the model's favour. Historically the two sides average 47% Over 2.5 across their same-competition games (Rayo Vallecano 60%, Espanyol 33%), a base rate that agreed with today's under. Their combined BTTS history runs at 47%, which matched the one-sided outcome.
Trading Patterns vs Reality
Rayo Vallecano's trading profile (15 games, 7 home) set some clear expectations: BTTS lands in 53% of their matches — today it did not.
Espanyol's trading profile (15 games, 7 away) set some clear expectations: BTTS lands in 40% of their matches — today it did not; they keep a clean sheet 40% of the time, and conceded here; they fail to score in 33% of games, a blank that repeated today.
Form vs Result
The form lines were close — Rayo Vallecano 1.60 PPG, Espanyol 1.33 PPG — offering no strong steer, and the Rayo Vallecano win broke the near-deadlock. Rayo Vallecano (home/away splits) managed 1 against a 2.29 scoring average — below par going forward.
Verdict
Grading the result against the stored data, 3 of 3 pre-match signals came in: result (hit), Over 2.5 (hit), BTTS (hit). The data earned its keep here, calling the bulk of the fixture correctly.
