West Ham striker Sebastien Haller has flown over to Amsterdam as he closes in on a £23million move to Ajax.
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 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.
Haller enjoyed two seasons in the Dutch Eredivisie with Utrecht between 2015 and 2017, scoring 51 times in 98 games.
