Florentino Pérez insists Real Madrid will fight any sanctions for fielding an ineligible player in the Copa del Rey victory over Cadiz on Wednesday night.

Rafa Benitez had Denis Cheryshev in his XI even though he should have been suspended after he received three yellow cards in the Copa del Rey last season for Villarreal. 

Cheryshev was withdrawn from the action moments after half-time, when Real had realised their error, with the head coach, Rafael Benítez, saying they wanted to “show good faith.”
