Much of the pre-match talk centred on Danny Drinkwater but it was another former Leicester player who returned to haunt them as Chelsea won 2-1 at the King Power Stadium.
N'Golo Kante, Drinkwater's central-midfield foil during the Foxes' 2015/16 Premier League title-winning season, was his usual energetic, tidy self and capped a typically consistent display with a goal from 25 yards to double Chelsea's lead after Alvaro Morata's opener.
Jamie Vardy pulled one back for the hosts from the penalty spot, but Antonio Conte's team held on for the three points.
Kante made the move to Stamford Bridge last summer and Drinkwater followed him on transfer deadline day last month in a £35million switch.
