Newcastle reportedly believe James Maddison is interested in joining them when the transfer window opens in January.
The Tyneside club expressed interest in the England international this summer, but the move did not materialize.
Leicester want to keep their star, but with only two years left on his contract, they could be forced to sell.
Maddison is valued at close to £50m and Newcastle would be willing to pay the amount for the 25-year-old.
Leicester City is going through a rough patch with results but is also in financial trouble as the salary bill is so high and the club has failed to reach the Champions League since 2017.
