Chelsea have condemned "unacceptable" homophobic chanting they allege came from a section of Manchester United supporters at Monday night's Premier League meeting in west London.
The visitors were 2-0 winners in the game at Stamford Bridge, after headers scored in either half courtesy of Anthony Martial and Harry Maguire.
In a statement posted on the club's official website, Chelsea FC say fans were stopped from entering the stadium and even ejected from the game as a result of the chanting.
"Chelsea Football Club has today issued the following statement following Monday evening's Premier League game at Stamford Bridge...
"At last night’s match a large group of Manchester United supporters made unacceptable homophobic chants. A number of these away supporters were prevented from entering the stadium and others were ejected during the game.
"This behaviour will not be tolerated at Chelsea Football Club. Those supporters will be banned from attending matches at Stamford Bridge in future, and in cooperation with Manchester United we have passed the details of those supporters to them so they can take appropriate action.

"Chelsea Football Club is a diverse and inclusive club and will always take firm action against all forms of discriminatory behaviour."
The result of the match itself moved United up to seventh in the Premier League table, three points behind fourth-placed Chelsea.
Blues manager Frank Lampard had criticised the use of VAR after the game, particularly the decision not to send off United skipper Harry Maguire for an apparent kick-out at Michy Batshuayi.
"Maguire should get a red and then he scores a second goal. The game changes off that.
"That was a major part of what VAR was brought in for, a second viewing, different angles. The referee can’t see all the angles, and if you’re not going to look at the monitor then you’re definitely not going to see it.
"It’s harder to take with the presence of VAR than it would have been before. That is what it was brought in for. It’s very confusing when all the different angles still bring the wrong decision. It’s universally a wrong decision. It could be my opinion, but everyone I’ve spoken to, not just in our dressing room, but neutrals have said the same."
