On 30 January 2013, Varane made his "El Clásico" debut against Barcelona in the 2012–13 Copa del Rey. He stopped a group of dangerous attempts from Barcelona, including a shot from Xavi that he cleared from the goal line. He capped his performance with a headed goal in the game, which ended 1–1. He also became the second-youngest foreign player to score for Real Madrid in a Clásico match. In the return leg at the Camp Nou on 26 February 2013, Varane scored Madrid's third goal in a 3–1 away win with a header from a corner kick by Mesut Özil. Varane gained praise from former World Cup winner Bixente Lizarazu after his performances against Barcelona and Manchester United. He said, "We are talking about a kid at Real Madrid who has unseated Pepe, and Pepe, with all his stuff, is still a great centre-half. His performance against Manchester United and Barcelona was extraordinary". Varane continued to impress in the Champions League quarter final first leg against Galatasaray, where he helped Madrid keep a clean sheet in a 3–0 triumph. All of his 27 passes found his teammates without any interception, and all of his tackles succeeded, with most on Didier Drogba.
