The Italian boss feels Leicester's new approach plays into his midfielder's hands.
The Algerian international has been with the Foxes since they were in the Championship, but has seemingly saved his best performances yet for the biggest stage of all.
Incoming manager Claudio Ranieri has inevitably been cited as one of the more obvious factors behind Mahrez's upturn in form, and the Italian has now given his verdict on why the 24-year-old is playing so well at present.
Appearing on talkSPORT on Tuesday evening, the one-time Chelsea boss reasoned that the midfielder's showings have come as a result of his alterations to Leicester's set-up.
"I changed something because last season they used to play with three at the back, five midfielders and two strikers," Ranieri said. "I wanted to play with the two wingers, Albrighton and Mahrez, and they have responded very, very well."
Whatever the remedy was for Mahrez, it has been one that has paid off handsomely for Leicester and Ranieri, who are flying high at the top end of the Premier League table at present.
After six games, the Foxes are the only unbeaten team in England's top flight, and along with West Ham, are the top scorers in the division with 13 goals to their name.
