Real Madrid coach Jose Mourinho said he is not worried by the jeers from fans in the 4-1 victory against Athletic Bilbao on Sunday.
Mourinho received whistles from the Santiago Bernabeu crowd during the match as the fans presumably protested against the club's inability to overcome Barcelona in direct confrontation.
"There is no problem, it did not happen to me at Porto, Chelsea or Inter, but there is always a first time for everything," Mourinho told a news conference.
"Here, (Zinedine) Zidane received whistles, just like Ronaldo and Cristiano Ronaldo. Why could not I receive whistles?"
"Zidane, Ronaldo and Cristiano responded with their goals. I will try to respond with my work."
Mourinho then stressed there is no reason for crisis talk at the club, despite Wednesday's 2-1 defeat to Barcelona in the first leg of the Copa del Rey quarter-finals.
"This is the first time that I am five points clear at the top," he said.
"We passed the group stage in the Champions League and we still have one match to play in the Copa del Rey."
"If we are beaten, it will not be by Alcorcon but by Barcelona and I do my job."
Meanwhile, Real striker Jose Callejon was happy with his side's display at the Santiago Bernabeu.
The 24-year-old came on as a late substitute and scored Madrid's last goal.
Callejon believes it is possible to defeat Barcelona in the second leg of the Copa del Rey quarter-finals on Wednesday, despite their 2-1 deficit.
"We reacted to their goal the way we had to," he said.
"We played good football to get this victory. I came on and I used my freshness to score the goal. I got a wonderful pass."
"Now we have to think about the Copa del Rey match as something very important. It will be very hard but we can win if we play like this."
