"I see a lot of people saying where did it go wrong for us," Platt told Sky Sports News.
"I think we have had a little bit of a lack of consistency and not won as many games as we could have but you have to give Manchester United credit for the pace they set because the amount of games they won, it would have been hard for any team to stay with them."
"The problem Sir Alex and Roberto have is that the media will write certain things and ask certain questions and both managers will give honest answers of what their opinions are, what they believe and then that question gets fired back as a quote," he said.
"And if we are not careful we get into the realms of tit for tat, and you said this and I said that. I think there is a deep respect from both managers for each other, I think there is a deep respect from both sets of players and both football clubs - there is a rivalry as there should be in the main city."
Platt says City are determined to bounce back and mount a title challenge next season.
"There has to be a determination amongst ourselves. It is not good when you hurt, when you lose it. When you set a season off and you think that you have an opportunity to win it like we did, and like they did last year, that feeling, that hurt is much deeper and more profound than when you win it."
He says City are now determined to end the season in style and win every game, including the FA Cup final against Wigan.
