The East Midlands club is ready for the Turkish champions to launch a bid for the Algeria international who has failed to impress since signing for the then-English champions in 2016 in a club record £28m deal.
The Foxes want to recoup most, if not all, of that fee which may prove an insurmountable barrier to a deal. Slimani scored 57 goals in 109 appearances for Sporting Lisbon, but at Leicester has seen his record fall to 12 in 43.
Claude Puel, the Foxes new manager, will not stand in the way of Slimani’s departure with Newcastle United and Watford thought to be on the Algerian’s trail. He recently admitted at a press conference that he had to sell to buy reinforcements for his squad.
Deeming his squad overloaded with attackers, Slimani is the most saleable asset he has. The French manager is not keen to sell Jamie Vardy, who turned down a move to Arsenal in 2016.
Besiktas though are looking to progress in the Champions League and need to add to their squad before facing Bayern Munich in the Round of Sixteen. Having received £27m for Tosun, a fee in excess of £20m is not beyond their reach.
