Manchester United could be sanctioned after sections of their travelling support were accused of aiming homophobic chants towards the Chelsea fans.
United ultimately came out on top in the game, earning all three points thanks to goals from Anthony Martial and captain Harry Maguire.
The result was massive in the race for a spot in the Champions League, with the gap between Chelsea in fourth and United in seventh closing to just three points.
However, the game is now threatening to be overshadowed by an off-field incident after away fans were accused of homophobic chanting.
According to the Sun, the authorities are waiting to read the referee’s report, which may make note of the alleged incident, before launching an investigation.
It is not the first time this season that opposition fans have been accused of aiming homophobic chants towards Chelsea supporters, with the club making an official complaint to Kick It Out and the FA back in December about West Ham.
The Hammers later condemned the chants in a statement which read: “West Ham United in no way condones any behaviour that falls short of the highest standards which the club sets when it comes to equality.

“At the London Stadium against Arsenal we will be celebrating and demonstrating the great work the club does to create a welcoming and inclusive environment for ALL supporters, including our LGBT+ fanbase, as part of our ongoing and unwavering support for the Rainbow Laces campaign.”
Kick It Out also addressed the incident, saying: “We have informed the FA, and reiterate our message: the ‘Rent Boy’ chant is homophobic and must be treated as such.”
Just over a week later, Everton also condemned the same chants being aimed at Blues fans during their 3-1 win at Goodison Park.
