Hammers are growing tired of waiting for an answer from Carroll.
West Ham United are interested in signing red-hot Vitesse Arnhem front man Wilfried Bony this summer, according to reports in the Sunday Telegraph.
The Hammers had been hoping to be able to persuade England international Andy Carroll to join the East End club on a permanent basis for next season, after the Liverpool striker had spent the previous campaign on loan at Upton Park.
However, West Ham manager Sam Allardyce is now said to be less confident of signing the 24-year-old attacker for £15.5 million and so is preparing to move on to his second-choice marksman, Ivory Coast international Bony.
Bony, 24, has just enjoyed a prolific season in front of goal for his club in the Eredivisie, where he was the top scorer with 31 goals in just 30 matches for his club.
And ever since signing for Vitesse from Sparta Prague in Jan 2011, the player has found goals easy to come by, netting 46 in 65, form which could seal Bony a £12m switch to the capital this summer.
