Real Madrid missed the chance to leapfrog Barcelona at the top of the La Liga table, with a 0-0 draw at home to Real Betis.
Zinedine Zidane's side were unable to break down their organised visitors at the Santiago Bernabeu, with Karim Benzema and skipper Sergio Ramos both missing first half chances.
However the closest his side came to breaking the deadlock was on six minutes, as Eden Hazard was denied a goal, after VAR ruled him to be offside from Benzema's pass.
Rubi's side had opportunities to edge in front before the break, with summer signing Nabil Fekir and man of the moment Loren Moron bringing saves from Thibaut Courtois.
Los Blancos struggled to increase the tempo after the break, with Benzema and Hazard well shackled by the Betis defence.
Zidane brought on Luka Jovic and Vinicius Junior in the closing stages, as the home side looked to force the issue, but it was to no avail, as Rubi's side held firm.
