After both Roberto Mancini and Mario Balotelli both marched up to the official, the Dane admitted he has never experienced a conclusion to a football match quite like it
Roberto Mancini was fuming at the final whistle of the Champions League tie, storming onto the pitch at the Etihad Stadium after seeing Sergio Aguero have a goal disallowed due to Aleksandar Kolarov being ruled offside, and a penalty appeal by Mario Balotelli turned away on the final whistle.
The 47-year-old then confronted the Danish referee on the field, with striker Balotelli also having to be held back by captain Vincent Kompany as he tried to approach the officials.
Despite tempers boiling over, neither Mancini nor his controversial forward will be punished by Uefa after match officials failed to report the incidents in their reports.
Rasmussen claimed he has never been involved in such a heated aftermath to a game, adding that receiving criticism never feels good but he can understand why he did.
"It's the first time I have experienced such a chaotic end of a match," Rasmussen told Sporten.dk.
"It's never nice [with criticism], but that can happen when a match progresses like it did."
The result leaves the Premier League side all-but out of the competition, needing to win their two remaining games, at home to Read Madrid and away to Borussia Dortmund, as well as holding out for help from other results.
