Jose Mourinho has not set foot in the Santiago Bernabeu since leaving Real Madrid in 2013, but his Champions League homecoming with Benfica on Wednesday will be far more complicated than initially anticipated.
The Argentine will miss the second leg after UEFA provisionally suspended him for one game amid an investigation into the incident.
Mourinho, who won a La Liga title with Los Blancos during three years at the helm, made a big impact on the Spanish giants during a period of particularly bitter rivalry with Barcelona and a dressing room divided for and against him.
