Roberto Mancini will escape disciplinary action from UEFA for his post-match altercation with referee Peter Rasmussen after Manchester City's 2-2 draw with Ajax.
City manager Mancini confronted the Danish official to complain that Sergio Aguero, who had scored his side's equaliser in the Champions League clash, then had a winner disallowed.
But as neither referee Rasmussen nor UEFA's match delegate reported the incident, the Italian will not face a fine or a touchline ban.
Mario Balotelli had to be restrained by captain Vincent Kompany after the final whistle when he attempted to get to Rasmussen to argue he should have won an injury-time penalty but the striker, too, will not be punished.
A UEFA spokesman said: "Nothing was reported neither by the delegate nor by the referee. No disciplinary proceedings are opened."
Defender Pablo Zabaleta admitted that City were annoyed by the officiating, especially when Aleksandar Kolarov was incorrectly deemed offside before setting up Aguero.
The right-back said: "We knew it was not offside, and on the penalty we were frustrated by the decision. We were frustrated and disappointed by the referee's decisions, but in the end you can do nothing."
"We were unlucky with the last goal because I think Kolarov was onside. I think the referee and linesman were wrong. When you fight to the last minute to get the three points, I think we deserved the third goal."
The draw leaves City with just two points from their four Champions League games and on the brink of elimination but Zabaleta is vowing not to give up.
He added: "Now it's going to be really difficult, but mathematically we are still in with a chance, so we need to fight.
"The next game [against Real Madrid] is really important, against probably one of the best teams in Europe at the moment, so it's going to be exciting."
