The Foxes are on track for Champions League qualification.
And Heskey told GentingBet: "The good thing about Leicester and Brendan is that he's got an owner that will back him. Leicester are in a position where they don't necessarily have to do anything – they don't need to sell any of their players.
"If he wants to keep players like James Maddison or Ben Chilwell then he can but if he wants to sell them, then you're commanding some high figures for the both of them. Chilwell would be £60 million, Maddison would be the same. So, you're talking £120 million which is a lot of money especially if Leicester are able to produce another little gem for just a fraction of that price. On the whole, Leicester are in a very good position."
