Clubs can now be charged by the Football Association if their fans use a homophobic chant that has been aimed at Chelsea players and supporters.
The chant has allegedly been sung by Manchester City and Nottingham Forest fans in recent matches against Chelsea.
Manchester United fans also allegedly directed the chant at Everton boss Frank Lampard during Friday's FA Cup match over his links to the Blues.
The FA has always condemned the use of the chant.
On Wednesday, the FA said it has now written all clubs across the Premier League, EFL, National League, Women's Super League, Women's Championship and steps two to four of the pyramid to remind them it can "pursue formal disciplinary action against any club whose supporters engage in discriminatory behaviour", which now includes this chant.
