Kylian Mbappe netted twice to earn Real Madrid a 2-0 win at Villarreal and take his side to the top of La Liga.
Alvaro Arbeloa's team moved two points clear of arch-rivals Barcelona, who host bottom-of-the-table Real Oviedo on Sunday.
La Liga's top scorer Mbappe reached 21 goals for the season in the competition to help Madrid see off a spirited Villarreal side, who are now fourth.
Arbeloa's side have won three consecutive matches across all competitions and victory at Villarreal could be a vital step in the revival of their season.
After the shock Copa del Rey defeat at second-tier Albacete in Arbeloa's first match at the helm just 10 days ago after replacing Xabi Alonso, his Madrid have started to take shape. The coach has made clear how important his star players are and none has been more crucial this season than French superstar Mbappe, who has netted 34 times across all competitions.
Mbappe and Vinicius Junior "are the best players in the world, they are players who can really unbalance teams, we try to get the ball to them as much as possible," Arbeloa said. "They're two players who... I'm really happy to have in this state of form and above all, because of the great work they are doing.
"They are really committed to the team, they are the first who are pressing... they're giving this effort and solidarity that we need from them, so I'm very happy that their reward comes in the form of goals."
