Barcelona 6-1 Villanovense (agg 6-1): Sandro hits three for second-string Barca

Sandro Ramirez hit a hat-trick and Munir El-Haddadi struck twice for a Barcelona second-string side in a 6-1 win over Villanovense 6-1 to reach the Copa del Rey last 16.

With big names including Lionel Messi, Neymar and Luis Suarez rested, it was a chance for Barca's younger players to shine after a goalless first leg and Sandro and Munir took full advantage with deadly performances.

It was always going to be a tough task for third-tier Villanovense but keeper Jose Fuentes could have done better with Dani Alves's opener after four minutes, before giving the ball straight to Sandro to score a second.

Juanfran Guarnido pulled a goal back after 29 minutes but two minutes later Sandro pounced again. Barca piled on the misery after the break with Munir scoring twice and Sandro getting another in between.

The tie was brought forward due to Barca's involvement in the Club World Cup this month and the other first-leg matches, including Real Madrid's clash with third-tier Cadiz, take place later on Wednesday.

"Sandro and Munir scored again but they have a lot of improving to do," Barca coach Luis Enrique told reporters after the clash.

"They are good friends and have a great understanding. They were always good strikers and I have a lot of belief in them."
