Christian Benteke is considering his future at Crystal Palace having grown increasingly disillusioned with the Eagles, according to theTelegraph.
The striker's row with Andros Townsend at the end of last weekend's win against Middlesbrough has fuelled rumours that he is discontent with life at the club.
Benteke was reportedly angry that Townsend had not passed the ball and opted to shoot late in the game, and appeared to square up to the England international before Boro goalkeeper Victor Valdes intervened.
Benteke has reportedly become frustrated with his teammates at Palace, although manager Sam Allardyce attempted to play down the incident after the win.
The Belgian forward is believed to be concerned about the more direct tactics employed since the arrival of the new coach, often leaving him isolated in attack. He has scored just once since Allardyce's arrival in late December.
Benteke has previously rejected interest from China, but in the Premier League West Ham are reportedly interested. Clubs in Italy, Germany and Spain are also said to be monitoring the powerful frontman.
West Ham could be willing to offload Andy Carroll who has also been the target of Chinese Super League clubs, in order to free up space to bring in Benteke.
Chelsea boss Antonio Conte, meanwhile, is a fan of Benteke, but would likely be unable to meet the player's demands for first team football.
Palace would hope to recoup around £25m of the £33m they paid to sign Benteke from Liverpool last summer.
