Teenager Arda Guler scored twice as Real Madrid cruised past fourth-tier Deportiva Minera to reach the last 16 of the Copa del Rey.
Federico Valverde netted a volley after just five minutes before Eduardo Camavinga doubled Real’s lead eight minutes later, heading home from Fran Garcia’s cross.
Valverde then turned provider for Turkey winger Guler, who made it three on 28 minutes with a left-footed strike into the bottom corner, before Luka Modric’s low drive found the back of the net after the break.
Guler added a fifth just before full-time, turning home from Garcia’s square ball.
This was Carlo Ancelotti’s side’s first match in the tournament this season as they missed the first two rounds because of their participation in the Spanish Super Cup.
Real Madrid are 20-time Copa del Rey champions but were knocked out in the last 16 last season by Atletico Madrid.
Jude Bellingham was rested after he missed a penalty then scored a 95th-minute winner against Valencia last week in a dramatic 2-1 La Liga victory.
