Chelsea are looking to extend their lead at the top of the Premier League to six points by claiming a victory over relegation battlers Sunderland on Wednesday evening.
The Blues, who are chasing their 10th consecutive win, head into the match three points clear of second-placed Arsenal - who were defeated by Everton on Tuesday.
They beat West Brom last time out, Diego Costa striking in a hard-fought home win over Tony Pulis' men, and head into tonight's match knowing they are overwhelming favourites against the Premier League bottom side.
