The Barca midfielder feels that Los Blancos are frequent moaners about decisions that go against them, and he said that it is time for Madrid to accept defeat gracefully.
"Madrid crying about the referee? They always look for excuses," he told reporters after the match.
"They have no reason to complain, not today, not earlier this season.
"The easy excuse is the referee. Same as always. They cannot complain at all this season about the officials. But if they will, they will."
Gerardo Martino's side are currently top of La Liga.
