Chelsea have welcomed the Crown Prosecution Service's decision to define a chant that has been aimed at their players and fans as a homophobic slur.
The CPS said last week that fans singing the slur during matches were committing a hate crime.
It added that those found to have used the words could face prosecution.
Chelsea said they "will not hesitate" to take action against individuals who continue to sing the chant.
Premier League clubs Liverpool, Leeds, Tottenham and Everton have all condemned their fans for singing the homophobic chant this season.
Spurs condemned a section of their supporters for allegedly signing the chant during their Carabao Cup semi-final first leg-defeat at Stamford Bridge this month.
