Real Madrid midfielder, Casemiro has blamed his side for their 3-0 defeat to Sevilla in the La Liga fixture played on Wednesday.
Three first half goals from Sevilla stars, Andre Silva and Wissam Ben Yedder ensured victory for the hosts.
Casemiro said Los Blancos lost because Madrid’s players didn’t play better in the first half.
“We gave away the first half,” Casemiro told Movistar. “We did not play like we have played all season.
“[Sevilla] are a very difficult opponent and, if we give away 45 minutes, this happens.”
Asked whether the reverse made the derby more difficult, the Brazil international added: “Each game is difficult. When playing the derby at home we have to get points. They are a great rival.”
Meanwhile, Julen Lopetegui’s men will take on Atletico Madrid in their next La Liga fixture on Saturday.
