Coach Carlo Ancelotti opted to rest several key players in preparation for the upcoming Spanish Super Cup in Saudi Arabia, with Kylian Mbappe and Vinicius Junior coming on as substitutes in the second half. Valverde opened the scoring with a volley at the back post, and Camavinga extended the lead with a header just 13 minutes in. Endrick nearly scored a third before Guler found the net, benefiting from a deflection after cutting in from the right side.
In the second half, Brahim Diaz struck the post before the 39-year-old Modric scored with a beautifully curled shot. Guler finished the match with ease after being set up by Fran Garcia, marking a successful outing for the Turkish playmaker.
On Saturday, both Barcelona and Atletico Madrid also progressed to the next round, while defending champions Athletic Bilbao narrowly advanced via penalties against third-tier Logrones. The draw for the next round is scheduled for Wednesday, with matches set to occur between January 14-16.
