Danish referee Peter Rasmussen was thrust straight into the spotlight when Yaya Toure was brought down by Christian Poulsen in the box early in the game but the official decided against awarding a penalty.
City had two more contentious decisions in the closing stages of the game when Sergio Aguero had a goal disallowed for offside despite team mate Aleksander Kolarov appearing to be onside while Mario Balotelli went down after his shirt was tugged in the box but no penalty was given.
With City now on the brink of elimination from the competition, Mancini was clearly unhappy with the decisions that went against his side and denied them the crucial victory to keep their hopes alive.
"The referee and linesmen had a bad night. It should have been a goal [Aguero's disallowed effort]," Mancini told Sky Sports.
"We were close to getting the miracle we needed. Unfortunately we took only one point and I think we are finished in the Champions League now.
"I think we played a good game. We did very, very well in the second half, creating a lot of chances and scoring three goals [including disallowed goal].
"But the referee and his linesmen were really poor."
He continued: "I don't know [why it did not count]. I said it was a goal and not offside.
"I don't know how it is possible for one linesman to consider that wasn't a goal - incredible."
Mancini conceded that it will be difficult to expect City to make it to the next stage with matches against Real Madrid and Borussia Dortmund remaining and rued the poor defending that allowed Siem de Jong to score a brace.
"I think that we played well. We conceded two goals from corners, then the game was changed, but after that we played very well, and created lots of chances. It is finished. I always believe in my team but now I think it is very difficult." he added on Uefa's official website.
"We have two more difficult games left, which we have to try and win. If we win two games, get eight points and go through, we can win the Champions League, it is simple - if our destiny is this then we should win the Champions League.
"We had a chance to win in the [Santiago] Bernabéu but we made some mistakes, against Ajax away it was the same, we did not play well but we took the lead and had two chances to score the second goal but we didn't take the chances. It was the same thing tonight [Tuesday], but it is finished."
