Barcelona have booked their place in the last 16 of the Copa del Rey with a comprehensive victory over Cartagena over two legs.

Gerardo Martino's side won the second leg of their round-of-32 tie 3-0 at home to wrap up a 7-1 aggregate success.

Pedro broke the deadlock for the Catalan giants at Camp Nou just past the half-hour mark to put the hosts in the driving seat.

Then midway through the second half Cristian Tello etched his name on the scoresheet and Neymar found the target two minutes from time to wrap up the victory.
