Real Madrid head coach, Carlo Ancelotti has taken full responsibility for their 3-1 defeat to Atletico Madrid on Sunday night.
Los Blancos came into the game top of the LaLiga table with an unbeaten record.
Alvaro Morata scored twice for ths hosts, while Antoine Griezmann also got on the scoresheet.
Ancelotti, speaking after the game, dismissed suggestions that tactics were a concern on the night.
Instead, the Italian claimed defensive shortcomings and a lack of intensity cost the visitors.
“We didn’t start well or defend well. When they went 2-0 up, they played the game they wanted to. Atleti did better than us in this sense.
“I think the system was not a problem, but rather defensive fragility. We were not compact and they took advantage of it.
“When the team doesn’t do what it has to do, it’s my responsibility. I shoulder that, it’s my fault,” Ancelotti said.
