The three Premier League outfits are all lookout for an attacking prospect to bolster their attacking ranks and have identified the Benin striker as a possible signing this summer.
Mounie joined the recently relegated Premier League side in a £12m deal from Montpellier, and looks set to leave the Terriers following their relegation to the Championship.
Mounie has 11 goals during his two-year stay in England, registering 63 appearances in all competitions under both David Wagner and Jan Siewert.
Palace manager Roy Hodgson is desperate to add options to his attacking unit, especially with star winger Wilfried Zaha reportedly keen on a move away from Selhurst Park this summer with Premier League side Arsenal F.C.
Crystal Palace has a total of 51 goals in their 38 Premier League matches last season, with midfielder Luka Milivojevic the club’s top scorer with 12 league goals.
A move for the Benin striker could well be realistic for the club and Huddersfield could be more than willing to accept an offer below the £12m they paid Montpellier two years ago, however, Palace will have to battle both Newcastle and Watford.
