Chelsea striker Loic Remy is a fall back option for West Ham.
The Mirror says Remy is under consideration - but only if they fail to land their primary targets.
Boss Slaven Bilic has confirmed an approach to Juventus for their Italy striker Simone Zaza with the 25-year-old keen on a move to the London Stadium.
Bilic is also interested in a loan move for Manchester City's Wilfried Bony while the Hammers retain an outside chance that AC Milan's Carlos Bacca could perform a u-turn on his decision to reject an offer from them.
If the club fail with those players they could then turn to Remy at the end of the window.
