Real Sociedad hosts in-form Rayo Vallecano, model gives hosts 48% edge

Real Sociedad arrives at Anoeta sitting fifth in the table, while Rayo Vallecano comes in twelfth, seven points back. But the recent form of both clubs suggests a tighter match than that gap implies, and that's what makes this LaLiga clash interesting.

Pellegrino Matarazzo's side has racked up six wins, one draw and four losses so far this season, scoring 20 goals and conceding 20 across 11 matches played. Over their last five outings, Real Sociedad have won three, lost one and drawn one, a stretch that includes a solid run of form before their most recent stumble. Rayo Vallecano, meanwhile, have three wins, three draws and four losses in 10 league matches, with 15 goals scored and 20 conceded. In their last five games, the Vallecano side drew twice, lost once and won the other two, closing out that span with signs of improvement.

Looking only at home matches, across a sample of five LaLiga games this season, Real Sociedad average 1.408 goals scored and 1.408 goals conceded per match, keeping clean sheets in 20% of those games and showing a tendency to score within the first 15 minutes. Luka Sucic leads the scoring charts in that sample with 4 goals, followed by Orri Oskarsson with 3 and Ander Barrenetxea with 2. Rayo, playing on the road over that same five-game sample, average 1.32 goals scored and 2.86 conceded, without a single clean sheet in those five matches, and they too tend to score early, in the 0 to 15 minute window. Sergio Camello tops that list with 7 goals, ahead of Alvaro Garcia with 3 and Jorge de Frutos with 2.

The head-to-head record doesn't point to a clear favorite either: across 8 meetings, Real Sociedad have won 2, Rayo Vallecano have won 2 and there have been 4 draws, with the home side scoring 13 goals and the visitors 12 across that overall tally.

Likely lineups

For Real Sociedad, the probable lineup is expected to feature Unai Marrero in goal, a back line of Mamadou Sarr, Sergio Gomez, Jon Martin and Igor Zubeldia, Jon Gorrotxategi and Goncalo Guedes in midfield alongside Ander Barrenetxea, and up front Mikel Oyarzabal, Luka Sucic and Orri Oskarsson. This lineup is projected from recent matches with moderate reliability, so it shouldn't be taken as confirmed.

Rayo Vallecano, with the same caveat, could field Emil Audero in goal, a defensive line of Adria Pedrosa, Mujaid Sadick, Florian Lejeune and Ivan Balliu, Unai Lopez, Pathe Ciss and Pedro Diaz in central midfield, and an attacking trio made up of Sergio Camello, Jorge de Frutos and Alvaro Garcia.

What the numbers say before kickoff

Our model gives Real Sociedad a 48% chance of winning, while a draw and a Rayo Vallecano victory each sit at 26%. In other words: the hosts are favorites, but this is far from a sure thing.

Those expected goals figures, an in-house estimate rather than an official statistic, point to a combined total of 3.07, in line with the 70% probability our model assigns to the match going over 2.5 goals and the 60% chance of both teams scoring. With those odds and the head-to-head record in mind, Anoeta is shaping up for an open match, the kind that stays undecided until the final whistle.
