Chelsea have made a formal complaint against referee Mark Clattenburg after accusing him of using "inappropriate language" to two of their players in the controversial defeat to Manchester United.
The European champions confirmed they have reported Clattenburg to the Premier League match delegate after the fiery 3-2 loss at Stamford Bridge.
A club spokesman said: "We have lodged a complaint to the Premier League match delegate with regards to inappropriate language used by the referee and directed at two of our players in two separate incidents in today's match. The match delegate will pass the complaint to the Football Association. We will make no further comment at this time."
