Roberto Mancini, Mario Balotelli and Sergio Agüero could all face Uefa charges after the trio confronted referee Peter Rasmussen at the end of Manchester City's 2-2 Champions League draw with Ajax.
Mancini was infuriated that Agüero had been denied a goal - which would have put the Citizens 3-2 up - for offside. Replays showed when Edin Džeko laid the ball off for Aleksander Kolarov to cross the Serbian was in line with the ball, rather than ahead of it. The Italian also began to remonstrate with an ITV cameraman who followed him off the pitch.
Balotelli meanwhile was enraged at full-time after Rasmussen declined to award him a penalty. Balotelli appeared to be pulled back inside the box but instead Rasmussen blew the final whistle after the ball went out of play off of an Ajax player.
Mancini and City players confront Rasmussen
Rasmussen had awarded City a free-kick - which lead to Balotelli grappling with Ricardo van Rhijn - having ignored a foul by Agüero on Siem de Jong seconds earlier, compelling many to suggest the Danish referee had attempted to even up his wrongdoings.
When asked what he had said to Rasmussen, Mancini replied: "I said it was a goal. I didn't see the last situation with Mario, but my players say it was a penalty. The referee and his staff were really poor tonight. I said to the referee that it was a goal. 'Congratulations, it was a goal'.
"What did he [the referee] say back to me? Nothing," he replied.
Mancini is angered by the cameraman
Regarding what happened with the cameraman, the City coach said: "He wanted to do a film with me and he followed me all over the pitch. I said, 'finish, finish.' It is not a film about me, it's a game. I said to the camera 'finish, go'."
He also angrily denied he had made a slashing gesture across his throat. "You think that I can say this to the cameraman? I understand what you said, but it's not true," he assured.
Mancini's side came from 2-0 down after two De Jong goals from corners to level through Yaya Touré and Agüero but remain winless after four games.
City can still qualify for the knockout rounds but must beat Real Madrid at home and away at Borussia Dortmund as well as hoping Ajax can deny Madrid victory in the Bernabéu.
The Blues can now only take a maximum of eight points - two less than the 10 they tallied last year when they were eliminated at the group stage.
Ajax, who have four points compared with City's two, entertain Dortmund on the next Champions League matchday.
