Real Madrid maintained their unbeaten start to the new La Liga season after an uneventful goalless draw at city rivals Atletico.
The result was enough to return Zinedine Zidane's men to the summit after they had been temporarily usurped by new boys Granada prior to the evening kick-off.
Real came closest to breaking the deadlock 10 minutes from time when Karim Benzema forced a superb save out of Atletico keeper Jan Oblak.
Otherwise the defences were well on top in a game that also saw Atletico move into a share of second place, still one point behind their rivals.
Earlier, newly promoted Granada extended their remarkable start to the season as a 28th minute effort from Antonio Puertas gave them a 1-0 win over Leganes.
Barcelona eased the pressure on under-fire boss Ernesto Valverde as goals from Luis Suarez and Junior Firpo earned them a 2-0 win at Getafe.
Valverde's side had made their worst start to a season in 25 years and were without an away win in eight attempts.
And their win did not entirely prevent their early season headaches as Clement Lenglet was sent off late on for a second bookable offence.
Getafe had chances to heap more woe on Valverde before Suarez struck the opener four minutes before half-time after latching onto a long ball from keeper Marc-Andre Ter Stegen.
And Firpo effectively wrapped up the points four minutes into the second period when he poked home the rebound after Carles Perez's initial effort was blocked.
Valencia ended a three-match winless steak as Denis Cheryshev's 27th minute strike gave them a 1-0 win at Athletic Bilbao.
Cheryshev struck on the counter-attack to grab the points for the visitors and move them up to ninth place in the table.
