Luciano Vietto's hat-trick has helped Valencia record a 4-0 win over Las Palmas to fire Los Che into the quarter-finals of the Copa del Rey with a 5-1 aggregate victory.
With the tie poised at 1-1 from the first leg ahead of the return encounter at the Mestalla, Marcelino Garcia Toral's charges took the lead on the half-hour mark.
Vietto, who had not scored a single goal in 2017, broke the deadlock with his first shot for his loan club, slotting home on the rebound after Simone Zaza's header was parried by Las Palmas goalkeeper Raul Lizoain.
The Argentine, on the books of Atletico Madrid, doubled his tally shortly after the restart with a neat dink over Lizoain, before Nemanja Maksimovic put the game to bed with the hosts' third goal - and his first for the club - on 54 minutes.
Vietto saved his best for last, completing his hat-trick on 66 minutes with an audacious effort from around 40 yards out which soared above the Las Palmas backline and goalkeeper before dipping into the net.
