Claudio Ranieri may have kept hold of Jamie Vardy and Riyad Mahrez but selling N'Golo Kante was always going to leave a void at the King Power Stadium.
The small but ferocious midfielder was absolutely vital to the Foxes' title charge and the release clause in his contract meant it was always going to be difficult for Kante to resist the lure of a bigger club.
In the end, Chelsea won the race for his signature but not before Kante's Leicester teammates made a last-ditch bid to keep him with the Premier League champions.

Marc Albrighton, Danny Simpson and Christian Fuchs has shed some light on Kante's departure and revealed one of the more unusual approaches they took to try and convince him to stay.
The Leicester trio spoke to Sky Sports before their shock opening day defeat to Hull City and discussed their very modern method of persuasion.

"There was a WhatsApp group, but if the player wants to leave then you can't stand in his way," Albrighton said.
Simpson added: "Obviously, you want to keep the same squad and same group of players but it's up to the individual.
"He got a lot of messages, everyone wished him well… before we deleted him out of it."
Ouch, so almost as soon as Kante had signed on the dotted line, Leicester's stars cut ties with the French international.
The title winners aren't prepared to spare much of a thought for the 25-year-old now he has moved for pastures new and Fuchs is confident they will cope without their midfield lynchpin.
The Austrian continued: "No one was very worried that the team would fall apart. We have an atmosphere here, which is something special, and now we are playing in the Champions League and that's something special too.
"You're better off having players who want to play for the club than those who want to leave or who are unhappy. We have new players that fit in very well and will be able to replace the others."
Fuchs might be eating his words now after Ranieri's side lost 2-1 to the newly promoted Hull and looked uncharacteristically frail at the back throughout the game. Clearly replacing Kante may not be as easy as they thought.
Mahrez can probably expect similar treatment from his teammates should he also manufacture a transfer away before the window closes.
Arsenal have been heavily linked with a possible move, however, Ranieri has reiterated that the Algerian is not for sale repeatedly during pre-season.
