The Italian took the Foxes to the Premier League title in 2016 but was sacked in February. Ranieri, now 65, took over at French club Nantes in June.
But he said he is never allowed to forget the miracle of Leicester's title triumph.
“I realise it because I am recognised a lot more – people everywhere from Japan to New Zealand have congratulated me," Ranieri claimed. “It really pleases me. But me, I don't think about it. I have never watched images of the title win or the party."
