Real Madrid coach Zinedine Zidane was critical of his side after a 1-1 draw with Valladolid in their first home game of the Spanish La Liga season.
Karim Benzema spun and shot from the edge of the area after 82 minutes to score his second goal in two league games.
That should have seen Madrid make it two wins in two so far this season but complacency crept in on Saturday.
Valladolid's Oscar Plano got the better of Raphael Varane and crossed for Sergi Guardiola to level with two minutes remaining at the Santiago Bernabeu.
Zidane, who started with James Rodrigues and Gareth Bale in his XI, was left to lament the hosts dropping points.
"We did the most difficult thing which was to score," he said.
"Our second-half performance was not the best, but we scored, and in just a few minutes we conceded. We were out of position.
"The first half was good. But we could not score and so the result leaves a bad taste.
"It's not so much losing the ball, because that can happen, but we were out of position to defend.
"We have to kick the ball out of the danger area. We know we have to play the 90 minutes. We can't just play 50 or 60 minutes."
Madrid had peppered Valladolid's goal in the first half, but Bale and Rodriguez, who received an ovation when he was substituted early in the second half, both sent shots wide of Jordi Masip's goal.
In the second period, Zidane introduced Luka Jovic for his home debut and he headed onto the bar from a Bale cross.
But Valladolid never gave up the result and might even had won the game with another Guardiola chance.
"In the second half we played the way we wanted to, and that's why we were able to equalise," Valldolid coach Sergio Gonzalez said.
Gabriel Fernandez got the only goal of the game as Celta Vigo accounted for Valencia 1-0 in the day's late game.
Earlier, hosts Getafe and Athletic Bilbao shared the points after Jaime Mata responded to Raul Garcia's sixth-minute goal for the visitors in a 1-1 draw while promoted Osasuna drew 0-0 with Eibar.
