Alejandro Grimaldo converted the resulting penalty, and Jonathan David later added a second for the hosts. Antonio Rüdiger headed a late consolation for Mourinho’s side, but it proved too little, too late.

"He even brought printed images of the incidents into his press conference to emphasise his point.
Real Madrid later released an official statement echoing their manager’s frustration, describing the defeat as “marked by the poor officiating” of referee Miguel Angel Ortiz Arias.
The result leaves Mourinho’s side six points behind leaders Barcelona after suffering their second La Liga defeat of the season.
