Gary Cahill and Willian issued a Chelsea rallying cry ahead of their Manchester City clash

Gary Cahill and Willian issued a Chelsea rallying cry ahead of their clash against Manchester City at The Etihad on Sunday.

The defending Premier League champions have endured a week of controversy involving a fallout between manager Jose Mourinho and some members of his medical staff.

The Blues already have some work to do this season after the west London side drew 2-2 with Swansea City at Stamford Bridge last weekend.

And Chelsea defender Cahill, who didn’t enjoy the best of games against the Swans, took to Twitter to rally his Blues team-mates.

Man City v Chelsea is the late kick-off on Sunday.
