Karim Benzema scored in the first half before Sergio Ramos added a second, while Marco Asensio killed the tie late on after Luis Muriel had scored a free-kick.
Los Blancos were very rarely troubled, as Atalanta once again failed to lay a glove on the Spanish giants despite the late goal from Muriel.
So, who performed best in the Spanish capital?
✔️ Karim Benzema 7.8
Benzema's goal set the tone but he was a big presence throughout. He should have scored another, but his overall play deserved great credit.
Nobody had more shots than his four, with two on target, and he completed four dribbles; he was constantly driving the team on and showed great leadership qualities.
He very nearly scored a second before he saw a header saved, with his follow-up attempt hitting the post.
❌ Marco Sportiello 5.1
Atalanta's goalkeeper never really recovered from making an error for the opening goal. He looked shaky all night, and struggled to take control of his area.
He did manage to get a hand to Ramos' penalty, but it was one he should have saved.
Even for Asensio's goal late on, his weak attempted save at the front post summed up his night.
⭐ Luka Modric 9.0
The Croatian was Madrid's key man, creating the first big chance of the night for the hosts He laid on Benzema's goal, but Atalanta didn't put him or Toni Kroos under nearly enough pressure in midfield. Defensively, he won four of his eight duels.
Modric and Kroos played the most passes on the night, and the former enjoyed 90% completion. It wasn't a particularly taxing night for the former Tottenham man, but he was still head and shoulders above all others on the pitch.
