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.
