Leicester would pay £17million for Maddison, who scored yesterday when Norwich beat Aston Villa.
They may go even higher as they expect a big windfall from Mahrez's exit, with Manchester City reigniting the race. Maddison, 21, plays a similar role to Mahrez with his trickery and unexpected skills. He is also capable of stunning goals.
The former Coventry babe may lack Mahrez's pace, but he would bring a match-winning presence to Claude Puel's team as they brace themselves for the loss of one of their stars.
