The Foxes' title win last campaign was unexpected, but it could be an even bigger task to shock the league once more.
It would be naive to suggest the bubble has burst just yet. Manager Claudio Ranieri still has a strong squad to choose from with youth and new signings, but the need for a strong start is crucial.
Can Leicester do a Leicester again? It's highly unlikely with the likes of Manchester City, Manchester United and Chelsea with new managers and strengthening once again, the inconsistency from all the top sides last term was staggering, so to see a repeat of that would be a shock.
The loss of Kanté seems particularly costly to Leicester because his extraordinary dynamism made him a key element in the title side and a player who could've coped with the increase in fixtures with Champions League football. European duties will obviously present a new experience for all at Leicester and questions will remain as to whether it will affect them domestically.
The most scrutinised of the new arrivals will be Nampalys Mendy, the midfielder tasked with filling the void for Kante. He doesn't match-up in terms of tackles or interceptions to the former Leicester man, but he is the same player who possesses energy and will look to grow in that role at the club.
Ranieri's side had the third lowest possession percentage average across the 20 Premier League sides, it will be interesting to see how sides will approach games at the King Power Stadium. Will they play Leicester at their own game which was so successful? These will be the kind of obstacles Ranieri will have to overcome this season.
Considering how much the big sides have strengthened, surely a top 10 finish would have to be considered a success for last season's champions.
Rather than dread a tough start to their title defence Leicester should relish the opportunity to steal some ground on their rivals, all of whom will be under heavy pressure to not have a repeat of last term.
