Manchester City boss Roberto Mancini refused to condemn goalkeeper Joe Hart after his howler in their 2-2 draw at FA Cup opponents Leicester City.
Hart fumbled a late routine save to allow Andy King to snatch a late equaliser.
Mancini refused to criticise Hart for the mistake that cost his side victory at the first attempt.
He said: "Has he said sorry? Yes, but his save in the first half and in other games were good.
"This can happen, it was unlucky."
