City have fallen seven points behind Barclays Premier League leaders Manchester United after suffering a shock loss at Sunderland on Boxing Day.
The lack of goals from strikers has been one of the factors for City's so far below-par challenge but - having overhauled an eight-point deficit with six games remaining last term - the club expect to come good.
Platt, first-team coach at the Etihad Stadium, said: "Seven points is a significant amount, there's no doubt about it.
"United are in the driving seat but there is half a season to go.
"I don't think it is insurmountable by any stretch of the imagination.
"It's not as though we are playing badly. We feel as though we are playing well, we are producing efforts on target.
"We are dominating possession and every statistic in most games, except goals."
