Real Madrid manager Carlo Ancelotti was pleased with his side's resilience as it earned a 2-1 win over Atletico Madrid at the Bernabeu in the hard-fought first leg of their Champions League round-of-16 tie on Tuesday.

Brahim Diaz scored the second-half winner after Atletico forward Julian Alvarez had canceled out Rodrygo's opener.

"It was a good goal but it's not over yet," Diaz said. "We still have to play the return match and give everything we have just like tonight. Nothing has been decided yet."

Diaz jumped the behind-the-goal boards to celebrate with Madrid fans who hugged him profusely, which earned him a yellow card.

"Playing here is something incredible, I always say it," Diaz said. "When you wear this shirt you have to give it all."

He was given a standing ovation at the Santiago Bernabeu Stadium when he was replaced by Endrick in the 89th.

Diaz was making his fourth Champions League start for Madrid this season, replacing Jude Bellingham because of a yellow-card suspension.

Vinicius Jr and Kylian Mbappe both missed good chances that could have given Real a bigger margin for the second leg but Ancelotti was not in the mood to lament missed opportunities.

He preferred to stick with the positive which is a win against what he considers one of Europe's best teams this season and said his players will need even more effort to make the most of their narrow advantage to advance in their title defense.
