The FA stands accused of not taking racism seriously after fining Huddersfield £50,000 for last month’s kit stunt - compared to £10,000 for Millwall for racist chanting.
It is being seen as the latest example of the struggle to prioritise the problem and comes as players across Europe call for black faces among the game’s rulers.
A section of around 200 Millwall fans chanted: “I'd rather be a P**i than a Scouse' during their FA Cup fourth-round win over Everton in January.
On August 1 they were fined £10,000 and told to "implement an action plan”.
The Football Association found that the south London club had "failed to use all due diligence" and ensure its supporters refrained from using racist language.
The paltry punishment came despite the FA confirming it had seen the evidence, posted in the form of video footage online.
A statement had said: “The FA investigated allegations of discriminatory behaviour and chanting after becoming aware of a video posted on social media.”
Huddersfield, relegated from the Premier League last season, were hit by the Football Association after wearing a kit in a friendly that breached advertising regulations.
The kit was worn as part of a sponsorship deal with a betting firm. It was quickly revealed as a spoof, with the deal actually seeing the club remove the sponsor from the front of their kit.
The slogan on the Championship side's shirt broke FA regulation C.2(i), which states advertising should consist of one single area on the front of the shirt, not exceeding 250 square centimetres.
The FA told an Independent panel: "The decision to enlarge the advertisement in such an overt manner was irresponsible, particularly in the current climate regarding gambling."
The FA’s written reasons included a statement from the referee Martin Coy, who stated that Huddersfield’s chairman, Phil Hodgkinson, had asked him to ban the kit, which “could then potentially be good publicity and part of the advertising campaign”.
"I was uncomfortable with this and felt it was not my place to ban the kit outright, but I informed them that I would recommend they followed the rules and advice from The FA," stated Coy.
Paddy Power themselves have hit out at the FA's decision
The gambling firm tweeted: "1st August: The FA fine Millwall £10,000 for supporters’ racist chanting.
"5th September: The FA fine Huddersfield Town £50,000 for wearing a fake shirt in a pre-season friendly."
