Real Madrid extended their unbeaten run to 38 games with a 3-0 victory over Sevilla in the first leg of their last-16 Copa del Rey tie at the Bernabeu.
Real – who has won 29 of those 38 matches – are one short of equalling a best-ever run by a La Liga team.
James Rodriguez scored twice as he made a rare start in the absence of the rested Cristiano Ronaldo.
Raphael Varne also headed home to put Real firmly in control with the second leg in Seville on 12 January.
Real Sociedad also took a huge step towards the last eight with Willian Jose, Carlos Vela and Mikel Oyarzabal scoring in a 3-1 win over Villarreal.
