Chelsea midfielder Nemanja Matic wary of Maribor

Chelsea midfielder Nemanja Matic has warned his teammates to "be very careful" when they host Maribor in the Champions League on Tuesday.

The Blues currently top Group G after taking four points from their opening two games, while the Slovenian outfit sit two points behind in second place.

Chelsea are expected to earn a win at Stamford Bridge tomorrow night, but Matic believes that the visitors are capable of causing an upset.

"These next two matches against Maribor are very important for us," he is quoted as saying by BBC Sport. "Maribor is a very good team and they played well against Sporting and Schalke so we have to be very careful with them."

Chelsea manager Jose Mourinho revealed on Monday that Diego Costa, Andre Schurrle, Ramires and John Obi Mikel are all injured for the match against Maribor.
