The latter had criticised Mignolet after conceding from a late Phil Jagielka wonder strike in the Merseyside derby but Schmeichel feels those words were 'out of order' and 'a character assassination.'
The Dane has thus defended his fellow goalkeeper and feels his former Man United team-mate is in no position to advise a shot stopper when he 'played right-back all his life.'
"I was shocked a couple of weeks back when it was a character assassination that Gary Neville did to Simon Mignolet," Schmeichel told BBC Radio 5 Live.
"I have to say I don't think the boy has done too bad since that night where he was taken apart by Carragher and Neville.
"It's very difficult to go on the pitch, everyone will be watching him, and everyone will be saying 'Oh this is what Neville's said, and this is what Carragher's said'."
"I'm looking at the goals and I'm thinking, 'What do you expect? Do you really honestly expect him to save everything?'.
"I just think what was done on Monday Night Football was out of order because it was a really, really good shot, and it was demonstrated how low he was, but by someone who's played right-back all his life."
