The Eagles have multiple alternative backup plans including Marko Grujic and Max Meyer
Crystal Palace have begun talks with West Ham to potentially sign Cheikhou Kouyate.
Roy Hodgson is searching for depth in central midfield, having lost two players in that position already this summer.
Yohan Cabaye left Selhurst Park on a free transfer to join Dubai’s Al-Nasr, while Ruben Loftus-Cheek returned to Chelsea after a loan.
As a result, the Eagles have opened talks over a deal which could bring Kouyate to the club, according to the Sun.
Hodgson is willing to spend £10m to secure the Senegalese midfielder’s signature this summer, but has alternative targets should the move be unsuccessful.
Chelsea’s Danny Drinkwater is one name on the Palace radar as he missed out on England’s 2018 World Cup squad partly due to the lack of playing time that he has been given since joining the Blues.
Liverpool’s Marko Grujic may also get the call, after spending last season on loan at Cardiff.
Released ex-Schalke midfielder Max Meyer is an additional name on the shortlist.
