Johnny Evans is claimed to be at the centre of a tug of war with the Hammers ready to offer top terms to the West Brom defender.
The defender is contracted to Albion until June 2019 and is reportedly hesitating on signing a new deal.
Manchester City are interested in him as a reinforcement but he is unlikely to get regular first team football at the Etihad.
It has left Evans with big decisions to make once the transfer window reopens in January.
David Moyes sees Evans as an in ideal Hammers signing believing the Irishman would add leadership to their leaky defence.
But Sam Allardyce too sees Evans as a key player in his team as faces the same issues at the back as the Hammers.
