Zinedine Zidane accepts that he could lose his job if Real Madrid's performances and results do not start to improve.
Real are 19 points behind La Liga leaders Barcelona and suffered an embarrassing exit from the Copa del Rey on Wednesday.
Zidane's team had won the first leg of their quarter-final against Leganes 1-0 but contrived to lose the second match 2-1 and crashed out of the competition on away goals.
Real face Paris Saint-Germain in the last 16 of the Champions League next month and Zidane knows that those two matches will be vital for his job prospects.
"Of course. That is really clear," Zidane said when asked if his job was on the line. "I am responsible for this, I'm the coach.
"So I must find solutions. I must take on the situation. I will keep always fighting, keep working, try and look for things to make the team better. Nothing more.
"I don't regret leaving out players. Some players needed to rest. On paper this was a competitive team, then in the first half no, we did not compete.
"I am very disappointed and will take responsibility for all this. But I will keep working. Tomorrow is another day, and what we must do is pick ourselves up and think of Saturday's game [at Valencia]. But today is a very hard blow."
Real are 3/5 to beat Valencia and 1/3 to qualify for the quarter-finals of the Champions League, a competition they can be backed at 4/6 to win for the third time in a row this season.
