Ajax are stepping up their interest in West Ham striker Sebastien Haller as they look to bolster their attack this winter.
Haller, who only joined the Premier League side 18 months ago for a club-record £45million fee, has scored just three league goals this season.
The 26-year-old has now become a target for Ajax with reports of the Dutch side lining up a £23m bid for the forward.
The Hammers therefore face a £22m loss on the player they signed on a five-year deal from Bundesliga outfit Eintracht Frankfurt in the summer of 2019.
However before allowing Haller to depart the London Stadium, Sportsmail understands David Moyes is keen for a replacement to have already walked through the door.
Bournemouth striker Josh King could fit the bill after struggling for game time at the Cherries this campaign.
The 28-year-old, who has entered the last six months of his contract, has fallen out of favour after he made it clear he wanted to leave the club.
West Ham had a £13m offer rebuffed in the summer transfer window and face competition from Premier League rivals West Brom.
Sportsmail reported earlier this week that Bournemouth have been open to bids but adamant they would not sell any of their assets on the cheap since their relegation last season.
