Chelsea are top of the yellow card table after seven Premier League matches and Sunday's fractious game with Nottingham Forest has raised the question: do they have an issue with discipline?
Manager Enzo Maresca played down concerns when asked but the Blues face an automatic £50,000 fine after referee Chris Kavanagh brandished them six yellow cards during the 1-1 draw at Stamford Bridge.
The Football Association (FA) are also awaiting analysis of the referee's report before deciding whether to take further action with forward Nicolas Jackson accused of slapping Forest defender Morato, while both clubs will likely face a charge of failing to control their players following an on-pitch melee.
