Chelsea manager Jose Mourinho chose to boycott the post-match press conference following his side's 1-1 draw with Manchester City.
It was the second time in two days that the Portuguese coach declined to speak to the media, following his no-show at the pre-match presser on Friday.
Mourinho's second boycott in two days could land him in trouble with the Football Association, who are expected to request an explanation for his absence.
The Blues boss was fined £25,000 earlier this week for insinuating that there is a "campaign" to influence referees to award decisions against his team.
He also reacted angrily to media reports about Diego Costa after the Spaniard stamped on Liverpool midfielder Emre Can during his team's 1-0 victory over the Reds in the League Cup.
