Karim Benzema scored the only goal as Real beat Atletico in the Madrid derby to go six points clear at the top of La Liga.
The French striker converted Ferland Mendy's cross from six yards out to give Real a deserved win.
Zinedine Zidane's side are now unbeaten in 21 games and have won eight in a row - including a penalty shootout success over Atletico in the Spanish Super Cup.
Second-placed Barcelona host Levante tomorrow.
