Los Blancos have given themselves a difficult home game to navigate and have to win by three goals in the second leg of their UEFA Champions League quarter-final.
The prospect of another season without silverware looms large, and Zidane admits even he didn’t expect such a bad result.
“I have all the responsibility, total, as coach,” he said. “We will watch the game again, and analyse it. I am responsible, and must look to see what happened. And I will do that.
“I am very proud of my players. We had chances, the only thing is we did not get what we wanted here. It is 2-0 and we must accept that. It hurts as we knew it would be difficult, but nobody, including me, expected this.
“We did not start with the necessary intensity for a Champions League game. We made that mistake. I am not going to go crazy now, as what we have done recently is positive. But this game we cannot be happy with.
“We will analyse it. It could be [due to] Saturday's game [the 2-1 win over Barcelona], physically we have suffered, above all in the first half. We lacked, above all, mobility in all the lines, at the start.”
