How bad are Chelsea's disciplinary problems?

Chelsea have received nine dismissals this season, although former manager Enzo Maresca, who was sent off for over‑celebrating a last‑minute winner against Liverpool, does not count in that total. Chelsea, bottom of the Premier League 'Fair Play' table, finished second‑bottom last season under Maresca and bottom the year before under Mauricio Pochettino. Maresca initially played down concerns before later launching his own review of the team's indiscipline prior to his departure.
