Jose Mourinho was left concerned after his Real Madrid side dropped points for a second consecutive game in an uninspiring 0-0 La Liga draw at Racing Santander on Wednesday.

However, the Portuguese added that he felt more positive about the performance than Sunday's shock 1-0 defeat at Levante and urged his players to be ready at home to face city neighbors Rayo Vallecano this weekend.

"We've dropped five points in two away games and that is worrisome," the former Inter Milan and Chelsea manager told a news conference.

"But it's less worrying to draw a match in which you're the only side that tries to play and win," he added.

"We've scored one goal in our last three games and we must return to normality by scoring and winning on Saturday."

Real lacked the zip and zest that inspired it to a 6-0 win at Real Zaragoza in its opening match of the campaign, as it bid to end Barcelona's three-year grip on the Spanish title.

Former World Player of the Year Cristiano Ronaldo, who sustained a gashed ankle in Champions League action last week, looked well below his best and Mesut Ozil, often the creative spark of the side, was largely anonymous.

"As a team we didn't do our best and some of our players performed under par," Mourinho said. "Our concentration was better tonight than it was on Sunday and I have a different overall feeling about the game."
