Reports have claimed that Mancini has already informed Hart that Pantilimon will be keeping his place for the showdown against Wigan Athletic at Wembley.
"He has no ill-feeling whatsoever towards Costel because he is a professional and wants what is best for the football club," the Daily Star quotes a source as saying.
"But on a personal level he is devastated. Football careers are short and who knows when he will get the chance to play in a cup final at Wembley again."
City will go up against their FA Cup opponents Wigan in the Premier League this week.
