Marco Asensio and Francisco "Isco" Alarcon were the big winners in a match that had little at stake for Real Madrid, reports Agencies.
The pair made the most of their chances in a second-string Madrid team on Thursday, scoring two goals each in a 6-1 rout of third division Melilla in the Copa del Rey.
Javi Sanchez and Vinicius Junior also netted as the European champion advanced to the last-16 stage 10-1 on aggregate after having won the first leg 4-0 in the small Spanish enclave in Africa.
Asensio and Isco used to have bigger roles for Madrid but haven't been getting many first-team opportunities under new coach Santiago Solari.
Vinicius played well throughout and claimed his second goal for Madrid with a shot from inside the area in the 75th minute at Santiago Bernabeu Stadium.
Isco was a starter for the first time under Solari and was named captain. He hadn't scored a goal since September but one of his strikes against Melilla came from a superb long-range shot into the top corner.
Asensio, a second-half substitute in the league last weekend, hadn't scored since the first leg against Melilla in October.
Meanwhile, Eibar were the first top-tier club to go out of this season's Copa Del Rey after a 4-2 aggregate defeat to Sporting Gijon.
Eibar rallied from 2-0 down on Thursday in the home leg of their clash but were eliminated 4-2 on aggregate by the second-division side.
Levante defeated second division Lugo 2-0 to advance 3-1 on aggregate. Jorge "Coke" Andujar and Raphael Dwamena scored late goals for the hosts at Ciutat de Valencia Stadium.
Athletic Bilbao repeated their 4-0 triumph from the first leg against Huesca to advance 8-0 overall. It was the third win for Athletic in 16 matches this season, in the team's first match since Argentine coach Eduardo Berizzo was fired.
Real Betis defeated third division Racing Santander 4-0 to go through 5-0 on aggregate.
