Chelsea have apologised for a tweet delivered after Eden Hazard's clash with a Swansea City ball-boy.

Chelsea apologised for a tweet issued on their official Twitter site following the incident.

It read: "Has football gone mad? Hazard is sent off for kicking the ball under a ball boy attempting to smother the ball rather than return it,"

They soon apologised, tweeting: "Apologies for earlier ballboy tweet. Hazard has now met with the ballboy and has said sorry. #CFC"
