Jose Mourinho was charged with improper conduct by the Football Association on Monday after being sent to the stands during Chelsea's 4-1 win over Cardiff.
There were a number of controversial incidents in the Premier League clash at Stamford Bridge on Saturday and Chelsea manager Mourinho was sent to the stands by referee Anthony Taylor for the final 20 minutes after losing his cool when a series of decisions went against his team.
Mourinho went to sit with the fans, making the day of those he sat next to, but his own frustration was clear.
Earlier in the match, Chelsea's Eden Hazard had scored a controversial equaliser after Samuel Eto'o dispossessed Cardiff's David Marshall as the goalkeeper bounced the ball, contrary to FIFA rules.
The former Real Madrid boss has been given until 1700GMT on Thursday to respond to the charge.
The nature of the offence means Mourinho is most likely to face a fine, rather than a ban.
