Madrid, Jan 10 (IANS): Vinicius Junior scored a goal and assisted on another in Real Madrid's 3-0 victory over Leganes in round-of-16 action in the Copa del Rey, Spain's annual knockout football competition.

The Blancos on Wednesday got off to a frustrating start at Santiago Bernabeu Stadium, with Karim Benzema squandering two early chances on a shot over the crossbar and a bouncing header into the arms of goalkeeper Cuellar, reports Efe news.

But Leganes also had a missed opportunity to rue when goalkeeper Keylor Navas dove to his left to save a powerful header by striker Martin Braithwaite.

Late in the first half, the Blancos' Alvaro Odriozola made his presence felt in the opposing goal area.

After a bizarre decision to pass instead of shoot in a one-on-one chance against Cuellar, he won a penalty just before first-half stoppage time when he was taken down by defender Rodri Tarin in the area.

Sergio Ramos then converted from the 12-yard mark to give Real Madrid a 1-0 lead heading into the intermission.

That advantage did wonders for the home side's confidence and level of play in the second half.

Although Vinicius missed out on a couple of chances to score, Real Madrid's constant pressure led to the second goal in the 69th minute.

On the play, Benzema capitalized on a defensive error to take possession of the ball in the area and pass off to Vinicius, who set up Lucas Vasquez for an easy score into a virtually empty net.

The final goal came off the foot of Vinicius, who volleyed home a pass from Odriozola in the 77th minute.

Leganes will have a massive hill to climb when they host the second leg of this Copa del Rey round-of-16 series at Butarque Municipal Stadium on January 16.
