Chelsea manager Jose Mourinho threatened to walk out of his post-match media conference over questions relating to Branislav Ivanovic's clash with Everton's James McCarthy in the Premier League leaders' 1-0 win at Stamford Bridge.
Willian struck a last-minute winner, but the main talking point occurred after Nemanja Matic thought he had scored four minutes from time, only for the deflected strike to be ruled out for offside against Ivanovic, with the ball deflecting off the Serbia international's shoulder and past Toffees goalkeeper Tim Howard.
Tempers flared when Gareth Barry then tripped Willian, earning a second yellow card, and Ivanovic motioned his head towards McCarthy in the resulting fracas.
Mourinho said after the game: "I'm concerned with my reaction because one more question I leave. The next question for that story I have to go."
Barry was booked for his part in the melee, but Ivanovic avoided censure from referee Jonathan Moss and could face retrospective action from the Football Association.
Mourinho told BT Sport: "Did Branislav Ivanovic go in with his head? Don't make me laugh. Don't make me laugh."
Mourinho, who was last month fined 25,000 pounds for saying there was a "clear campaign" against Chelsea, was not prepared to discuss the Ivanovic incident post-match or the possibility the defender would be banned.
Mourinho has already shown his displeasure at Diego Costa being suspended retrospectively for three matches for stamping on Liverpool's Emre Can.
The Blues boss continues to imply his side are unfairly treated and two decisions went in favour of Everton in the opening quarter of the contest.
Chelsea might have had a fourth-minute penalty when the ball hit Steven Naismith's arm, and Everton had another reprieve when Barry fouled Juan Cuadrado and Eden Hazard in quick succession, but was booked only for the first offence.
Mourinho added: "I'm tired of stories and I'm never tired of football. Football is emotion and what we had here today.
"A discussion because of a red card, a red card that should be given in the first half, because Barry should be sent off in the first half. He pulled Hazard. The second yellow card should be given there."
Mourinho, however, had no complaints with referee Moss' performance.
"I think it's a clear penalty. I also think the referee had a fantastic performance," the Blues boss added. "The official that disallowed the goal, it was a fantastic decision."
