The pre-game handshake for the west London derby has already been called off because Anton Ferdinand’s lawyers have argued that it could affect the trial against John Terry for an alleged racially-aggravated order offence.
The Blues ended the game with just nine men on the pitch at Loftus Road earlier in the season and, although an FA Cup match since went by largely without issue, the atmosphere is expected to be tense at Stamford Bridge.
A statement on the Blues' website read: “Sunday's match against Queens Park Rangers is a very important game for both sides and Chelsea Football Club hopes for a passionate London derby atmosphere, but without hatred or abuse.
|14/1||Chelsea and QPR are 14/1 with PaddyPower to draw 2-2 on Sunday|
“Chelsea FC appreciates that both teams enjoy fantastic support and we are pleased the behaviour of fans attending the FA Cup match at Loftus Road in January recognised that abuse and discrimination has no place in football or society.
“Now we wish for the same level of respect to be shown when the two clubs meet again in this weekend's league match.
“Both clubs will work together with the police to ensure that anyone using discriminatory or inflammatory language is identified and that the strongest possible action is taken against them.”
