Mourinho frustrated by the health issues: this is part of my job © EuroFootball.com

Jose Mourinho insists he is not worried that part of Madrid's fans booed him on Sunday.

Despite the capital's team celebrating a convincing 4-1 victory against Bilbao's "Athletic", fans still did not hide their dissatisfaction with the failure experienced in the middle of the week against the mortal enemy "Barcelona" club.

"There are no problems," Mourinho said at a press conference. "It didn't happen to me while working with the "Porto", "Chelsea", and "Inter" teams, but there is always a first time."

"Zinedine Zidane was once booed here, as well as Ronaldo and Cristiano Ronaldo. So why shouldn't I also join this group? The players responded by scoring goals, and I will try to do my job as well."
