Chelsea are attempting to recapture consistency in the Premier League, and the Blues host Burnley on Saturday at Stamford Bridge.
Frank Lampard's men won seven consecutive games in all competitions during September and October, but have earned just seven wins in their last 16 matches.
Five Premier League losses in quick succession has harmed Chelsea's top-four ambitions, but their rivals have failed to capitalise fully on the slump.
Burnley have been hugely inconsistent this term and sit 15th in the league, just four points above the relegation zone.
