The Foxes made the decision to wield the managerial axe after returning from the November international break and losing 2-1 at home to Chelsea.
Goals either side of the half-time whistle from Nicolas Jackson and Enzo Fernandez secured the points for Enzo Maresca, who was facing his former employers as Blues boss.
Andre Ayew converted from the penalty spot in added-on time for the Foxes, however defeat for the hosts at the King Power Stadium was essentially confirmed by the lateness of the consolation.
Winless across their last four matches in the top flight, Leicester are currently occupying 16th place in the Premier League standings, one point above Ipswich Town in 18th.
Leicester considering Potter as Cooper successor?
According to TBR Football, Leicester are already well into the search for a successor to Cooper, who survived just five months at the East Midlands outfit.
The report claims that Graham Potter is attracting the interest of the Foxes, who are desperate to avoid an immediate return to the Championship after their title-winning campaign of 2023-24.
The 49-year-old has been out of work since April 2023 after being relieved of his duties at Chelsea, now waiting for the right time to get back into management.
It is understood that Leicester have commenced their due diligence on Potter ahead of potentially appointing the promising English coach as Cooper's successor.
The former Brighton & Hove Albion was supposedly interviewed for the Ajax job over the past year but opted to bide his time as he seeks out a fresh coaching adventure.
Where did it go wrong for Cooper?
With strong links to East Midlands neighbours Nottingham Forest, Cooper was possibly destined to struggle at the King Power as Leicester boss.
Following the exit of Maresca to Chelsea in the summer, the Foxes lost the man who had guided them back to the Premier League at the first time of asking.
Rumours of the first-team squad being unhappy with Cooper's laid-back approach emerged right at the beginning of the term and failed to die down.
