Mancini was very critical of Nasri's performances this season and the Frenchman confirmed he'd taken it on board and now understands how he can develop as a player.
In 27 Premier League appearances this season, Nasri has scored only two goals but notched up seven assists.
“I know if I’ve played well or if I’ve played s*** and for eight months I wasn’t good. I understand what the manager was saying, because it must be frustrating when you have a quality player and he doesn’t perform and you don’t know why because you try to play him there, play him there, but he still doesn’t perform.
“So at some point you have no choice but to put him on the bench and you go to the press to try to get a reaction. And it worked. Arsene Wenger would never criticize a player in public. Sometimes you have players who have a big ego and if you say something in public they are going to react."
Nasri, who has been heavily linked with a move to French side PSG, reflected on City's derby defeat to Manchester United that saw Robin van Persie score a last minute free kick, courtesy of Nasri's poor attempt at a block.
"I don’t know what went through my head. I don’t know how many times I was thinking about it afterwards," Nasri continued.
“At the time I almost cried I was so upset with myself. How could you do that? It was a derby and with a draw we’d have stayed a few points behind them but they won it and it was a big moment in the title race.
"Before, I wasn’t very good at accepting public criticism. But he [Mancini] just wants the best from his players on the pitch because he has to win. If he doesn’t, he gets fired. So take it [the criticism] and show him you can play. Starting a war of words doesn’t fix anything. Just accept it, work hard and show it on the pitch."
When asked about the changes at Manchester United, Nasri said: "I think now everything is going to change. It is going to be different because you have to adapt yourself to a new manager, you don’t know if the new one is going to have the same power over the players.
“Ferguson could have a go at players like David Beckham, Cristiano Ronaldo. Will they accept it if David Moyes does the same to them?”
