Redknapp can understand neutrals now warming to the Blues.
He told the Daily Mail: "I'm loving watching Chelsea at the moment - they're electrifying.
"They're mirroring the image of Ancelotti, who was a top player, is a top coach and a top man.
"Some players' on and off-field behaviour put a lot of people off. Let's not get carried away, though, their season starts now with Man City, Marseille and Arsenal up next."
