Diego Costa has been ruled out of Chelsea's Champions League match against Maribor.

The two teams meet at Stamford Bridge tomorrow in matchday 3 of the group stage.

The striker has struggled to gain full fitness since joining the club in the summer and missed the 2 - 1 win at Crystal Palace, with Frenchman Loic Remy taking his place.

Mourinho says Costa picked up his latest problem while on international duty with Spain.

Andre Schurrle and Ramires are also ruled out.
