Former Manchester City goalkeeper Joe Corrigan felt Joe Hart produced the save of the season in victory over Manchester United.
David de Gea made a string of world class saves during the game.
But Corrigan told the Manchester Evening News: "I thought both keepers played very well. Joe Hart made one of the saves of the season.
"A shot came through a group of players and he made a great save down to his right hand side. It's one of the best saves I've seen so far this season and it was the reason City took all three points.
"De Gea played really well as well, to be fair to him. It was a one-off derby and the result counted more than anything else."
