Cadiz 1-3 Real Madrid: Comfortable win overshadowed by controversy

Real Madrid sealed a comfortable victory in their Copa del Rey clash at Cadiz - but could be booted out of the competition for fielding an ineligible player.

Denis Cheryshev had given Rafael Benitez's side the lead in their 3-1 win at the Ramon de Carranza but the Russia international had a one-game ban hanging over his head.

The 24-year-old had picked up three yellow cards during the competition for former club Villarreal last season and this was the first opportunity the winger had to serve the accompanying ban.

He was hauled off moments after half-time as a brace from Isco secured victory for the 19-time Copa del Rey winners, with Kike Marquez scoring a late consolation for the hosts.

Cadiz would have to report the situation to the Spanish Football Federation on Thursday and the club's Twitter feed, @Cadiz--CF, said during the game: "The Board of Directors of @Cadiz--CF will meet at the end of the match."

Real Madrid face Copa expulsion

Real Madrid could be expelled from the Copa del Rey for fielding an ineligible player.

Last season Osasuna were kicked out of the tournament for playing an ineligible player as Unai Garcia was selected in the win over Mirandes despite being sent off the previous year.

On the pitch, after making a string of changes, Benitez saw his side take the lead as early as the third minute as Cheryshev arrowed home a left-footed drive after a smart pass from James Rodriguez.

Lolo Pla and Wilson Cuero came close to equalisers for the third-tier outfit as they looked to hit back quickly.

Cheryshev then passed up the chance to add a second with Rodriguez unable to turn home Alvaro Arbeloa's pass as Madrid went in one ahead at the interval.

Mateo Kovacic then came on for Cheryshev just after the start of the second-half but the inclusion of the player in the starting line-up could result in Real's expulsion from the competition.

Madrid made sure of victory on the night as Isco struck twice, grabbing his first with a well-taken effort on 65 minutes and putting the visitors further ahead nine minutes later after more smart work from Rodriguez.

Substitute Marquez reduced the arrears with two minutes remaining but it remains unclear who will advance into the fifth round.
