Real, who made sure of a place in the last 16 of the Champions League with victory over Borussia Monchengladbach on Wednesday night, started brightly as Karim Benzema's drive was pushed onto a post by Oblak.

The home side took the lead after 15 minutes when midfielder Casemiro powered in a header from Toni Kroos' corner.

Diego Simeone's men, though, were finding it difficult to sustain any long spells of possession as striker Luis Suarez cut a forlorn figure, starved of quality service.

The Argentinian made a triple change for the second half, sending on Renan Lodi, Angel Correa and Thomas Lemar – who soon collected a yellow card for clattering into Casemiro.

French midfielder Lemar went close to an equaliser in the 55th minute when he fired into the side-netting after Marcos Llorente had put in a low cross to the back post.

Real Madrid doubled their lead in the 63rd minute.

Kroos' floated free-kick was headed back out towards Carvajal. The defender collected the ball on his chest before firing a long-range effort against a post and in off Oblak as he dived for an own goal.

Atletico finally forced Real goalkeeper Thibaut Courtois into a save when substitute Saul Niguez got on the end of Lodi's cross, before Lemar fired over.

Lucas Vazquez almost added a late third for Real, but Oblak pushed the ball over.

Madrid striker Benzema was making his 528th appearance for the club, breaking Roberto Carlos' record for the most appearances by a non-Spanish player.
