Bournemouth face a battle to keep hold of midfielder Harry Arter.
The Mirror says Crystal Palace are now rivalling West Ham's interest in Arter.
West Ham's new manager David Moyes is keen on Bournemouth's Republic of Ireland international as he searches for more mobility and bite in midfield.
Rock-bottom Palace are in a similar position to their 18th-placed London neighbours, with Roy Hodgson looking to freshen up the squad he inherited from the sacked Frank de Boer in September when the winter transfer window opens.
Arter, 27, signed an improved four-year contract in June – but a number of clubs are ready to test his commitment to Bournemouth.
