Real Madrid’s lead at the top of La Liga is down to five points after Xabi Alonso’s side were held by local rivals Rayo Vallecano.
The 36-time league winners were seeking to restore their seven-point lead at the top of the table after Villarreal moved into second with a 2-0 win away at Espanyol on Saturday.
But Vallecano, who had won three of their last five going into the match, proved stubborn opposition.
Defender Raul Asencio came closest to breaking the deadlock in the first half, but the Spaniard could not direct his header goalwards having been left unmarked in the box.
Former Liverpool defender Trent Alexander-Arnold came on for the final stages, but Madrid struggled to create clear-cut chances, with Vinicius Jr and Jude Bellingham squandering the side’s best sights at goal.
Barcelona can cut Madrid’s lead at the top to three points later on Sunday when they travel to Celta Vigo (20:00 GMT).
