Real Madrid star Cristiano Ronaldo has declared himself 'happy and surprised' at Barcelona's weekend defeat.
"There are no unbeatable teams, but I was happy and surprised," he declared.
Meanwhile, the Portugal winger has urged the Real fans who jeered their own side at the weekend to show more support.
Jose Mourinho's Madrid reign began with a goalless draw against Real Mallorca before Saturday's narrow 1-0 victory over Osasuna at the Santiago Bernabeu.
"It is better if the public help you to play better," declared Ronaldo.
"The energy spent on whistling is the same as what they can use to encourage us.
"I'm sure Mourinho will end up giving us a show. He is one of the best coaches in the world.
"We are a team under construction and we want to win a title this year."
Club legend Johan Cruyff has called for patience following Barcelona's shock weekend defeat at the hands of Hercules.
The reigning La Liga champions lost 2-0 to the newly-promoted minnows at the Camp Nou on Saturday evening with the scoreline sending shockwaves through Spanish football.
Coach Pep Guardiola handed starts to recent signings Javier Mascherano and Adriano but came under fire afterwards as he started with established stars Xavi, Pedro and Sergio Busquets on the bench.
But despite severe criticism of the coach and also the team performance in the Catalan press, former coach and player Cruyff has called for patience.
"Whenever you win in football, more is expected of you," he explained.
"In football you can lose to anyone when you take into account a number of factors.
"The club has introduced new players and it is difficult to implement a new style from the beginning.
"It is important to have confidence in this team because they have earned it."
