The 29-year-old claims that the Italian has put his stamp on the Foxes squad he inherited from Nigel Pearson since his arrival in the summer.
The Danish goalkeeper also recognised former manager Pearson's role in assembling the title-winning squad.
He said: "Claudio (Ranieri) has come in and inherited a well-assembled squad that Nigel Pearson had created with a good team atmosphere.
"He has built on that and tweaked it and put his own little stamp on it."
Leicester will finish their triumphant campaign with a trip to last season's champions Chelsea on Sunday.
