With the tie over as a contest following Real’s 7-1 first leg win and El Clasico away to Barcelona to come on Saturday, Zidane made nine changes from the side that started the 2-1 win over Sporting Gijon last weekend.
Norwegian starlet Martin Odegaard, 17, was also handed his full debut, but it was Dominican international Mariano Diaz who got Real off to a flying start as he slotted home the first of his hat-trick after just 23 seconds.
