Real Madrid used two penalties to cruise past third-division club Fuenlabrada 2-0 in their Copa del Rey round-of-32 first-leg tie on Thursday.
Zinedine Zidane selected a much-changed team from the one that defeated Eibar in La Liga play on Sunday, resting key stars Cristiano Ronaldo, Toni Kroos, Sergio Ramos, Raphael Varane, Marcelo, Luka Modric, Isco and Karim Benzema for the match in Madrid's suburbs.
And though their absence was felt through the first 45 minutes, goals from Marco Asensio and Lucas Vazquez were enough to give the defending league champions a comfortable advantage heading into the return fixture at the Bernabeu next month.
Real's youthful side -- featuring the likes of Asensio, Jesus Vallejo, Alvaro Tejero, Achraf Hakimi, Dani Ceballos, Marcos Llorente, Borja Mayoral and Theo Hernandez -- took a while to find their footing in the first half.
However, they picked up the pace after the break and finally found a breakthrough from the penalty spot on 63 minutes. Hakimi was brought down in the box by Fran Garcia, and Asensio slotted home from 12 yards to give Los Blancos a deserved lead.
They added to their advantage on the 80-minute mark, Lucas Vazquez scoring from the spot after Paco Candela was adjudged to have wrestled down Theo during a corner kick and was sent off for his second yellow card.
Madrid finished the match with 10 men, however, after Vallejo's first-team debut ended one minute from time as he was sent off following a heavy challenge.
