West Ham have invested heavily in their squad this summer, with club-record signing Felipe Anderson the latest through the doors in east London.
The Hammers have spent over £85m on new recruits under Manuel Pellegrini and are now looking to balance their books with a number of departures.
One of those looking set for an exit is Michail Antonio, after the arrivals of Anderson and Andriy Yarmolenko handed the winger a wealth of competition for his first-team spot.
The Daily Mirror state Antonio is poised to complete a £15m switch across London to join Crystal Palace, in a move that will trigger a domino effect in the market involving a number of Premier League clubs.
Once the signing of Antonio is complete, Palace could then approve the departure of Andros Townsend to join Newcastle, who in turn would then allow Matt Ritchie to complete a proposed move to recently relegated Stoke City.
