Real Madrid stumbled to a second straight draw at Santiago Bernabeu after being held 1-1 by Levante in La Liga on Saturday.
Madrid lost striker Karim Benzema to a right-leg injury four days before their Champions League title defense starts against Cypriot team Apoel.
Coach Zinedine Zidane will be without Marcelo for the next league match at Real Sociedad after the defender got a direct red card for kicking Jefferson Lerma in the head after they tumbled to the turf in the 89th.
With Cristiano Ronaldo serving the third of a four-match suspension – for pushing a referee – Zidane gave starts to newcomer Theo Hernandez and midfielder Marcos Llorente.
Newly promoted Levante caught Madrid with their guard down on the 12th minute via a routine throw-in executed by Ivan Lopez, which concluded in a goal by another teammate also named Ivan Lopez.
One Lopez directed the throw-in to the other Lopez, who slipped behind Dani Carvajal near the goal, controlled the ball and poked it past goalkeeper Kiko Casilla.
Gareth Bale replaced Benzema in the 26th when Madrid's striker grabbed his right leg and asked to be substituted.
Lucas Vazquez got the equalizer 10 minutes later, when he tapped in the rebound after Levante goalkeeper Raul Fernandez saved Sergio Ramos' header.
Bale was criticised by the home crowd after Madrid’s 2-2 draw with Valencia last round and the Wales winger squandered four opportunities to put the hosts ahead in this game. Bale sent three headers wide and failed to beat Fernandez one-on-one.
Toni Kroos almost grabbed the win for 10-man Madrid when he hit the post in stoppage time.
Madrid, the defending Liga champion, have only one victory in the first three rounds.
