David Platt has defended Manchester City manager Roberto Mancini following his outburst against Ajax.
The Blues chief ran on to the pitch after the 2-2 draw, which all but ends the north-west side’s participation in the competition, to remonstrate with referee Peter Rasmussen.
Man City striker Sergio Aguero had a goal ruled out for offside in the 88th minute and Mario Balotelli was denied an injury-time penalty as Rasmussen blew the final whistle.
Mancini also clashed with the cameraman who filmed him at close proximity as he walked across the pitch but later said he had only been telling him to stop recording.
First-team coach Platt said: "Why wouldn't the manager of a football club be frustrated? Why wouldn't we all be frustrated?
"Players are frustrated, supporters are frustrated, staff are frustrated.
"Robbie has gone onto the pitch and spoken to the referee. As he comes back, he turns around and has a camera in front of his face for 30 yards.
"He turns around and says, in English, that basically it is enough now.
"People then want to start talking about what has happened and almost exaggerating the incident."
Platt added: "I don't think he is the first manager to go onto the pitch.
"If you go on to Wikipedia you'll see has done it before, not just as a manager but as a player. He wears his heart on his sleeve."
