Real Madrid made it a record-equalling 39 games unbeaten with a 5-0 Spanish league win over Granada at the Santiago Bernabeu on Saturday.
The victory means they equal Barcelona’s Spanish record of matches without losing and can beat it when they play Sevilla in their second-leg, last-16 Copa del Rey game next Thursday.
Isco opened the scoring for the leaders in the 12th minute off Karim Benzema's pass - finding the net beneath the dive of Guillermo Ochoa.
It was 2-0 on 20 minutes when Ochoa failed to hold a Luka Modric shot and Benzema converted the rebound from an offside position.
Cristiano Ronaldo, who had presented his fourth Ballon d’Or trophy to the Santiago Bernabeu before the game, scored the third heading in Marcelo’s cross.
On 31 minutes Isco made it four from Modric’s cross. He had replaced James Rodriguez in the starting line-up but Rodriguez came on at the break and set up the fifth for Casemiro with a free-kick which the Brazilian converted at the back post.
The midfielder's goal means everyone in the current squad bar Fabio Coentrao has scored at least one goal so far this season.
“We played a very complete match and we could have scored more goals. We are very pleased with the way we have started the year," Modric said.
"The manager (Zinedine Zidane) has asked us to start games with intensity and that is what we did today. We had a week off and we came back we had a mini pre-season and we have come back very strong."
Zidane added: “It’s important to win but it’s also important how we do it and the supporters are enjoying watching Real Madrid.”
Granada's David Lomban said: “It was never a contest. We have to just think about the next game now. It’s very difficult to come here and get anything.”
In the second game of the day Atletico Madrid picked up a 2-0 away victory against Eibar.
Saul Niquez headed in Felipe Luis’ cross in the 53rd minute to put them ahead.
He looked marginally offside when he scored but Eibar could have no complaints about the second goal with Antoine Griezmann converting Kevin Gameiro’s cross.
“We struggled to get into the game in the first half but we were much better in the second half," Griezmann said.
“We feel we’ve got back the essence of what Atletico Madrid is – we are hard to break down and dangerous going forward.”
The result puts them back in the top four ahead of Villarreal who play on Sunday against Barcelona. Luis Enrique's side need a win to close Real Madrid's six point gap at the top.
Later Saturday Las Palmas host Sporting and Sevilla visit Real Sociedad.
