Chelsea's Oscar suffers injury during training

Chelsea might have to enter this weekend's important fixture without Brazilian midfielder Oscar.

Manager Jose Mourinho confirmed that Oscar sustained an injury during training and doubts that he will be available for Sunday's clash with Manchester City,

It's a tough blow for Chelsea after seeing its season begin with a disappointing draw against Swansea City, where Oscar was one of the standout performers.

Oscar's free-kick goal opened the scoring for The Blues at Stamford Bridge thanks to Swansea's failure to stop his cross into the box from finding the back of the net.
