Real Madrid manager Jose Mourinho has admitted that he is concerned with his side following their 1-0 defeat to Sevilla last night.

Mourinho was disappointed that Real, who were unable to equalise after going behind early on, have in his eyes only played well once all season.

"I worry about my team and that since the start of the official season we have only played well in the Super Cup, a little bit against Valencia and a little bit against Granada," Mourinho told the club's official website. "That is my concern rather than points.

"We have [to] work harder on set pieces and each player knows who he needs to mark and his job at set pieces. In the first minute [we conceded] a goal from a corner. This shows me the image of my team, lacking concentration, without being mentally prepared."

Real Madrid are currently 10th in La Liga with only four points from a possible 12.
