Antonio Conte admitted the "two faces" of Chelsea were evident after the Premier League champions were humbled 3-2 by Burnley at Stamford Bridge.
Gary Cahill was sent off in the 14th minute by referee Craig Pawson for a high lunge at Steven Defour and Burnley responded by powering into a 3-0 lead with two goals from Sam Vokes and a Stephen Ward strike.
Chelsea fought back through Alvaro Morata and David Luiz, but Cesc Fabregas' dismissal for two bookable offences disrupted their momentum in a second-half they dominated.
