Valencia have secured their passage into the sixth round of the Copa del Rey with a 4-1 aggregate victory over Osasuna.

Los Che held a two-goal advantage heading into tonight's tie at the Mestella, but still had work to do as Los Rojillos looked to upset the odds.

Neither side really threatened in the opening half-hour, but the game sprung to life when the hosts took the lead in the 34th minute.

The referee awarded a free kick when Jonas was felled by Ruben Gonzalez and Tino Costa whipped the ball low past Andres Fernandez from the resulting free kick.

However, Valencia's lead did not last long, as Joseba Llorente drilled a fierce shot past Vicente Guaita to restore parity.

The visitors started brightly in the second period, and nearly went ahead when Llorente met Alvaro Cejudo's cross, only to see it go agonisingly wide of the upright.

Lolo then made a vital interception at the other end to prevent Nelson Valdez from reaching Juan Bernat's centre.

Mauricio Pellegrino's men took control of the contest from the 60th minute and did not look like losing from then on in.

Victory was complete when Roberto Soldado found the back of the net in injury time.
