Enzo Zidane scored on his debut for Real Madrid as they completed the formalities of their passage to the fifth round of the Copa del Rey with a 6-1 win over Cultural Leonesa at the Bernabeu. But the woes continued for Barcelona as they could only draw at Hercules.
Zidane, the eldest son of coach Zinedine, replaced Isco at half-time and collected a pass from Mariano Diaz before cutting inside and firing into the bottom corner from 20 yards out just after the hour.
The win extended the club's unbeaten run to 32 games -- taking Zidane past Carlo Ancelotti's longest run without a defeat recorded during the 2013-14 campaign.
It sealed a 13-2 aggregate win against the Segunda Division B side, after Madrid won 7-1 in Leon last month. Madrid completed their fourth-round tie earlier than the rest of the teams in Spain due to their involvement in the Club World Cup next month.
Mariano, who also netted in the first leg, scored a hat trick -- the first coming after just 23 seconds, the fastest goal of Zidane's reign. James Rodriguez put the home side two up then Mariano struck again before half-time. Zidane's son scored the fourth before Mariano completed his treble and Cesar Morgado put through his own net. Yeray bagged the visitors' consolation just before the break.
A much-changed Barcelona side couldn't get the better of another Segunda Division B side, drawing 1-1 at Hercules.
Jasper Cillessen was named in goal and Samuel Umtiti made his return from injury in defence. Lucas Digne, Denis Suarez, Rafinha, Paco Alcacer and Arda Turan also got run-outs but Barca will have to finish the job back at the Camp Nou in two weeks.
David Mainz gave Hercules a shock lead in the 52nd minute, but Carlos Alena, the 18-year-old who has been linked with a move to Manchester United, spared Barca's blushes with an equaliser six minutes later.
Atletico Madrid put six past Guijuelo in their first-leg meeting away to the Segunda B side.
Saul Niguez opened the scoring from the penalty spot in the 29th minute, with Sime Vrsaljko adding a second for the visitors just before the break.
Yannick Carrasco scored twice to open the second half, and Angel Correa and Roberto Nunez added goals to wrap up the easy win for Diego Simeone's team.
Segunda Division club Cordoba shocked La Liga's Malaga 2-0 at the Estadio Nuevo Arcangel.
Second-half goals from Borja Dominguez and Rodri gave the hosts a first-leg advantage ahead of a visit to Malaga on Dec. 20 to complete the tie.
Sevilla effectively booked their passage with a 5-1 first-leg win away at SD Formentera. Joaquin Correa scored a 28-minute first-half hat trick, and his goals were bookended by a Wissam Ben Yedder brace. Gabri Gomez was on target for the hosts.
Villarreal are also completely in command of their tie, having won 3-0 at Toledo. An Adrian Jimenez own goal set them on their way before Cedric Bakambu and Samuel Castillejo added daylight.
Granada won 1-0 at home to Osasuna thanks to Jon Miguel Toral's goal, while Celta Vigo were 1-0 victors at UCAM Murcia through a Sergi Gomez goal.
