That lead had been stretched to 10-2 by the end of the first period courtesy of a double from Mariano Diaz and close-range header from James Rodriguez, while Yeray Gonzalez was on the scoresheet for the visitors.
Enzo Zidane, son of Real Madrid boss Zinedine Zidane, then made it 4-1 on the night just past the hour, before Mariano completed his hat-trick in the 88th minute and Cesar Morgado scored an own-goal two minutes later.
