The 20-man brawl during Chelsea's crucial 2-1 Premier League victory over Leicester saw both clubs hit with an FA charge.
As a result, Thomas Tuchel's side could be severely punished. That's according to the Mirror who say they were warned in July 2016 that they faced a points deduction after appealing against a £375,000 fine following a similar incident in a match against Tottenham two months earlier.
The report also adds that it is the SEVENTH time in as many years the Blues have been in the FA dock.
In the last five years they have been charged twice more for failing to control their players, but avoided any sanctions.
A source said: "It seems there's an issue within the club."
Chelsea and Leicester have until Tuesday to respond to the charge.
The prospect of a points deduction could have disastrous implications in Chelsea's season as they head into the final day of the campaign still seeking a top four spot.
Speaking about his team's game at Aston Villa, Tuchel said: "You get absolutely focused, absolutely sharp when the kind of pressure that we have now is on.
"These last two matches for us - against Leicester and now Aston Villa - even if the pressure was on before, they ARE - different. The situation is so clear now.
"It brings you to the edge. It brings you out of bed early. You think twice and become sharp. That's what I demand of myself - to deliver under pressure."
