Real Madrid remain top of La Liga after a 0-0 draw with Atletico Madrid on Saturday at the Wanda Metropolitano Stadium.
An intense first half saw few chances for either side. Joao Felix flashed two shots wide for the hosts, while Toni Kroos tested Jan Oblak with a couple of efforts from distance.
Atletico ended the half as the stronger side, and Real needed goalkeeper Thibaut Courtois to be alert to cut out a dangerous cross from Kieran Trippier intended for Koke.
Real Madrid had the better chances to break the deadlock after half-time. An unmarked Gareth Bale blasted wastefully over the bar after being set up by good work from Nacho Fernandez.
