Described as the best midfielder in this season's Premier League by former Manchester United manager Sir Alex Ferguson, Kante's ball-winning skills were key to the fast, counter-attacking style that has brought the title to the King Power Stadium.
The midfielder arrived shortly after the appointment of Ranieri, after Walsh persistently urged the Italian to secure a deal by telling him: "Kante, Claudio, Kante."
"We did have that conversation," Walsh told BBC Radio 5 live. "But obviously he took my advice, brought him in and the rest, as they say, is history.
"People think we play with two in midfield, and I say 'No. We play with Danny Drinkwater in the middle and we play with Kante either side, giving us essentially 12 players on the pitch.'"
