West Ham have been linked with a move for the former Arsenal and Manchester City striker Emmanuel Adebayor.
According to Daily Record, West Ham and Watford want to sign the player and the striker wants to join a London club as well.
Manuel Pellegrini has signed Haller as his number one forward this summer but he needs more depth in attack next season. The 35-year-old could prove to be a decent option off the bench for the Hammers.
Adebayor is unlikely to take up a lot of investment and West Ham should look to bring him in.
