Rayo Vallecano vs Girona FC: match statistics

Rayo Vallecano holds a clear form advantage — in the last 5 matches they have 4 wins and 1 draw (PPG 2.6) and have scored 8 goals, while Girona in their last 5 have only 1 win, 1 draw and 3 losses (PPG 0.8) and have scored 5 goals. At home Rayo averages 1.24 goals and xG 1.80 with 16.47 shots per game and 5.76 on target, which contrasts with Girona away — 1.00 goals, xG 1.20, 10 shots and 3.71 on target. Defensively the hosts are stronger: Rayo concedes 0.82 goals at home and has 41% clean sheets, while Girona concedes 1.53 goals away and has only 6% clean sheets; the goal difference (+7 Rayo vs -9 Girona away) completes the picture. Despite Girona’s higher conversion (10% vs 8% Rayo), the lower number of shots on target and the visitors’ poor form make the hosts’ chances of victory substantially higher; I estimate probabilities of 65% for the home team, 20% for a draw and 15% for the away team.

Seasonal data strongly support the BTTS - Yes for Girona: their season BTTS rate is 71% versus Rayo's 47%, while the league BTTS level is 56%. Both teams concede over 1.4 goals per match (Rayo 1.47; Girona 1.53) and their xG against are 1.57 and 1.77 respectively, indicating chances created for opponents. However, Rayo has shown very good defense recently — in the last 5 matches the hosts averaged 1.6 scored and only 0.6 conceded, with BTTS at 20% in that run, which reduces the likelihood of an opponent goal. Girona away have only a 6% clean sheet rate and have scored 36 while conceding 51 this season, and their BTTS in the last 5 matches is 60%, so their games often feature goals from both sides. Considering Girona’s dominant seasonal signal (71%), the league level of 56% and the high conceded averages 1.47 and 1.53, I tip BTTS 'Yes' at 63% probability versus 37% for 'No'.

I estimate total expected goals at approximately 2.94: home xG is 1.32 and combined with xG against Girona 1.77 yields ~1.55 for Rayo, while Girona xG 1.20 versus Rayo’s defense 1.57 yields ~1.39 for the visitors. Seasonally Rayo scores over 1.5 goals in 71% of matches and Girona in 88% (~80% on average), which strongly supports Over 1.5 and makes it the best line to play. For the 2.5 line seasonal rates are 53% (Rayo) and 47% (Girona), and with our xG-total = 2.94 the Poisson model translates this to roughly a 56% probability for Over 2.5. The 3.5 line is less likely — seasonally only 24%/12% and the model gives ~34% for Over 3.5, so Under 3.5 is statistically safer. Additionally, in the last 5 matches Rayo scored 8 goals (avg 1.6) and conceded 3 (0.6), while Girona scored 5 and conceded 7, which confirms the expectation of at least two goals in this fixture.

Rayo Vallecano have led at the break more often — the hosts were leading at half-time in 41% of matches, while Girona were trailing at half-time in 18% of their away games; averaging these rates I estimate the chance of Rayo leading at the break at roughly 30%. Form favors the hosts: Rayo have won 4 of their last 5 matches (80%), while Girona have won only 1 of 5 (20%), which increases the likelihood of Rayo maintaining their lead and winning in regular time. Rayo generate an average xG of 1.32 and 10.71 shots per match with a home goals average of 1.12, while Girona have an xG of 1.20, score 1.00 goals away and concede an average of 1.77 xG, suggesting an advantage for Rayo in chance creation. Since goals more often occur after the break (Rayo score on average 0.65 goals after half-time, Girona 0.53) and Girona have 100% of matches in the data with at least one goal after the break, there is a risk of a turnaround, but the form balance and home advantage favor Rayo for the final win, therefore I select the 1/1 scenario as the strongest signal.
