Gary Cahill and Cesc Fabregas were sent off as Burnley stunned nine-man Chelsea 3-2 on Saturday to ensure the Blues got their Premier League title defence off to a losing start at Stamford Bridge.
Chelsea were reduced to 10 men in the 14th minute when Cahill was sent off for a reckless challenge on Steven Defour, and they found themselves 3-0 down by half-time as Sam Vokes scored either side of a sensational Stephen Ward strike.
Substitute Alvaro Morata pulled one back in the second half, and he assisted David Luiz as Chelsea grabbed another, despite Fabregas picking up a second yellow card, but the Blues were unable to complete their comeback.
