Chelsea have made a complaint about referee Mark Clattenburg's language during their defeat to Manchester United.
Two accusations of using "inappropriate language" have been levelled against Clattenburg, who sent off Branislav Ivanovic and Fernando Torres during United's stormy 3-2 win.
Chelsea did not go into details, but a spokesman confirmed two separate incidents involving two different players have been reported.
And Sky Sports News' chief reporter Bryan Swanson identified one of the two players involved as midfielder John Obi Mikel, who was seen attempting to enter the referee's dressing room after the game.
The 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."
In a later statement the Professional Game Match Officials - the body which controls Premier League referees - said it was "aware of the allegations and they are being treated with the utmost seriousness.
"Mark will cooperate fully and welcomes the opportunity for the facts to be established".
Clattenburg was wearing a microphone during the game to help him communicate with his assistants, but conversations during the game are not recorded.
what do you think?

Never mind his language, what about his decisions! He's an absolute disgrace! He should be looked at properly by the FA because he doesn't even bother to hide his Utd bias anymore. And i'm not even a Chelsea fan.
andrew
Its not just his Utd bias either, he has made errors in so many games now, how he is given such a high profile match is beyond me.

Oh dear! Players can be foul mouthed and clearly seen by even non-lip readers on tele and get away with it! The ref maybe lost his cool on the day and suddenly the footballers and their club(s) don't like it - tough I say!

The ref may have made some questionable decisions, but people make mistakes. If you want to eliminate these you need give the video ref the power to overturn decisions. Finally with all of those cameras and microphones I am sure that if inappropriate language was used, then he will be brought to answer for them swiftly. Until then let them collect and examine the evidence before jumping to any conclusions

but oh dear the conversations on the mics arn't recorded! perhaps now they should be! and no i'm not a chelsea fan

"0ff" Quite appropriate
Jamie gormley
New it would belong before the chelsea fans and staff would start moaning. Big deal I can remember lots of times where they have bullied. Refs into given them free kicks or iffy spot kicks. Who cares what the ref said. Im sure terry has said much worse. Trouble with people from the south! They have to much to say. When the fair play rules kick it. It will be buy buy chelsea. Glory hunters with there fan base of 5yank years

Now then. An interesting situation eh? In my opinion the FA should turn to chealsea and say, yes he used inappropriate language, but tough. You get your players to stop talking to the refs like dirt and we will start punishing refs for inappropriate language. Football could learn so much from Rugby League, the respect, the technology and in my opinion the sin bin. But no, they won't accept that they have to incorporate ideas from a 'lesser' sport.

Not just Rugby League but Union as well plus almost every other sport in exsistance, why do footballers get away with the foul abusive language and players and managers trying to influence desicions.

Rugby ? you mean that game where thugs gouge and bite and punch each other ? No thanks, keep your "example"
Paul Nicholas
Yes Rubgy, a game where if you bite punch and gouge you get banned for months, even if no injury was caused. Also by the way, a game where diferent sides supporters sit next to each other in the stands, a game where you are not afraid to take you're family and people can enjoy a drink without any trouble happening and the players get together after the game and buy each other a pint. If soccer is you're example of a sport then no thanks, i'll keep Rugby any day of the week.

I thought he did alright. Replays showed Ivanovic touching Ashley Young twice and Torres could easily have kept going. As for Hernandez I bet all of you would get that wrong nine times out of ten
david conway
Agreed. Hernandez was linesmans job as ref was unsighted. Anyone unbiased can see Torres took an easy dive. Again. Bad timing for Chelsea to bring this up considering! We would have empty fields if the ref reported all similar players comments. Clattenberg does better than I or anyone elso could in such a cauldron.
Rob Shaw
I support neither team, and don't particularly like either team, but at the end of the day, as per usual, Man utd got all the decisions. I know people make mistakes, but if it had been just one questionable mistake, then it wouldn't of gotten that much attention. But Clattenburg just seemed hell bent on giving United everything. He got one right, and that was the Ivanovic sending off. Torres might have been able to stay up but it seems to be over looked that Johnny Evans went in 2 footed and still caught Torres. Clattenburg at least owes chelsea an apology for the mistakes, let alone what language he used
Lynn Price
fully agree with your comments, I am not a chelsea fan either but having watched the match Clattenburg was a disgrace. Valencia seemed to get away with a fair amount! also 2nd time in a couple of weeks that van persie as chucked his arm back at a player and escaped any booking
andy may
do players ever get embarrassed? these overpaid, foul mouthed, spoilt brats have the nerve to report a referee for "inappropriate" language. the majority of every premiership team can be seen at one point or another abusing the ref. maybe they need a moment of introspectiveness, they could pay somebody to explain what it means!
barry simms
Mark Clattenburg wasn't he given a second chance by the FA, dodgy business melt down, now its another dodgy business.
robali
I think Mark Clattenburg definitely got a decision wrong when he only booked Torres for the challenge on Cleverley. Should have sent him off then.
Peter Howard
Initial reaction is that it sounds like sour Grapes, but let's wait and see what evidence they come up with before final judgement is made.

Also keeping the fact that a Steward was hit by an object thrown from the crowd and taken to hospital out of the headlines.

Did the whole lip-reading industry take the weekend off, or are they most keen to suddenly keep their heads down? :)

just like scrotes who gob it off in the streets, when they get some stick back they start crying like little babies. vote with your feet, don't go to watch these idiots.

He had an utter shocker. Not unusual when it comes to MUFC.
