Millwall warned by Football Association after offensive chants by their supporters

Millwall finished eighth in the Championship last season

The Football Association says it will impose "a very significant financial penalty" on Championship side Millwall should there be any further cases of discriminatory abuse by their fans.

A disciplinary panel imposed an action plan on the club after they admitted three counts of abuse with "express or implied reference to religion".

The charges followed chants aimed at Wigan's James McClean in April.

Incidents occurred after eight, 12 and 45 minutes of the Championship game.

The action plan - which will be in place until the end of next season - includes making supporters aware of the charge and that the chants were offensive and constituted a criminal offence.

Millwall will conduct a full review of their stewarding and the training of stewards and "ensure that the prevention and detection of any discriminatory or inappropriate behaviour is sufficiently addressed, and is readily available for inspection by the Football Authorities and the appropriate Safety Advisory Group".

The club must also evaluate their CCTV and public address messages and work with bodies such as Kick It Out to promote its anti-discrimination policies.

Millwall have also been ordered to send two stewards to away matches deemed 'high risk', and warned about their future conduct.

"The club strongly condemns discrimination of all kinds and has a zero-tolerance policy against such abuse," Millwall said.

"Through the work of its industry-leading Equality Steering Committee, the club takes a very proactive approach to combatting discrimination and continues to work tirelessly on a wide range of initiatives and measures to help continue driving positive change."
