Real Madrid head coach Carlo Ancelotti was livid with his side after they "gave away two points" in Sunday's 3-3 LaLiga draw with Levante.
Madrid seemed in control leading 1-0 at the break following Gareth Bale's first LaLiga goal since 2019 but conceded two goals within 12 minutes of the restart to trail 2-1.
Vinicius Junior pulled a goal back in the 73rd minute before Rober restored Levante's lead with the Brazilian finding a leveler with five minutes to go.
"It was crazy, after controlling the first half well," Ancelotti told Marca. "We have given away two points after a very good first half.
"It is difficult to explain, we had to pay attention to any detail. We leave with a bad taste in our mouths. We have to be more attentive."
Los Blancos had started their LaLiga campaign with a strong 4-1 win away to Alaves but the Italian bemoaned his side's second-half attitude against Levante.
"The first half was very good," Ancelotti said. "In the second we did not enter with a good attitude. It was not a good response."
He added: "The third [goal] is bad luck. In the first [goal] we adjust the line badly and in the second [goal] we are three against two, and that cannot be."
Despite his frustrations, Ancelotti was delighted with the impact of 21-year-old Brazilian winger Vinicius Junior as a 59th-minute substitute and hoped he can build on his promise.
The Flamengo junior only scored three league goals from 35 appearances last term but has already equaled that output in two LaLiga games this season.
"He has a lot of quality," Ancelotti said. "He must score, but I don't know if he will be a great scorer.
"With that quality he must score many goals. It will be important for us. Sometimes it is more important to finish the games than to start them.
"It is not something that gives much importance, whether you are the owner or not."
