BARCELONA, Spain (AP) — Athletic Bilbao forward Iker Muniain celebrated his 21st birthday in style on Thursday, scoring two goals and setting up another to send the Basque side into the Copa del Rey's final 16 in a 4-0 victory over 10-man Celta Vigo.
Bilbao overturned a 1-0 loss in the first leg at Celta and advances to face Real Betis.
Muniain opened the scoring with a long-range strike in the 21st minute at San Mames, after Bilbao's pressure led to Ibai Gomez stealing the ball from Michael Krohn-Dehli in Celta's territory.
Markel Susaeta slipped behind his marker to tap home Ibai Gomez's cross to put Bilbao ahead on aggregate one minute before halftime.
Already struggling to many any impact in the final third, Celta's chances were further undermined in the 53rd when defender Hugo Mallo was dismissed with his second yellow card.
Muniain scored his second goal in the 80th before he sent Aritz Aduriz clear to cap the win five minutes from time.
Despite the assist, Aduriz said Muniain could foot the bill for the party.
"He gets to pay," said Aduriz. "Wow. Two goals on his birthday? It's his turn to pay."
Also, Valencia moved on after a nervy 1-0 win over third-division Nastic Tarragona. Rayo Vallecano advanced after rallying to beat 10-man Valladolid 3-1, and Espanyol defeated second-tier Real Jaen 2-0 for a 4-2 win on aggregate.
With interim coach Nico Esteve making his debut in place of the fired Miroslav Djukic and the tie poised at 0-0 after the first leg, Pablo Alcacer's headed Valencia's winner in the 37th.
