LONDON: Jose Mourinho was proved correct as Newcastle striker Papiss Cisse came off the bench to condemn Premier League leaders Chelsea to a 2-1 defeat, their first of the season.

Chelsea manager Mourinho had said several times that going through the season unbeaten was an impossibility and so it has proved.

The Senegal international struck with his sixth goal of the season four minutes after replacing Remy Cabella, and then added a second 12 minutes from time.

Magpies defender Steven Taylor was dismissed for a second bookable offence and substitute Didier Drogba headed Jose Mourinho’s men back into the game with seven minutes remaining to spark a desperate, but ultimately fruitless, late flurry.

It was Chelsea’s third successive league defeat on Tyneside and left Mourinho still awaiting his first win in the competition at St James’ Park.
