Liverpool are desperate to sign a defensive midfielder before the window slams shut in two weeks’ time.
They had a bid accepted for Moises Caicedo but the Brighton midfielder rejected them and joined Chelsea instead of travelling to Merseyside.
Southampton also accepted a bid from Liverpool for Romeo Lavia but the Belgian also rejected the Reds in favour of a move to Chelsea.
Doucoure has emerged as a target for the Merseyside giants but it has been claimed that Liverpool will have to dig deep for the Palace star.
The south London club are on the verge of losing Michael Olise and are reluctant to let another important player such as Doucoure at this stage of the window.
It has been claimed that Crystal Palace are unlikely to want to sell the midfielder unless they receive a fee worth £100m.
They have already watched two defensive midfielders move clubs for fees in excess of £100m in Declan Rice and Caicedo.
Crystal Palace are not interested in selling Doucoure for anything less than that figure this summer.
