West Ham are close to completing a deal for Leeds forward Crysencio Summerville.
The Premier League club has been linked with numerous players this summer as technical director Tim Steidten tries to strengthen Julen Lopetegui’s squad.
However, Summerville - last season’s Championship Player of the Year - has emerged as the London club's primary target.
Sources say talks are at an advanced stage and personal terms with the 22-year-old are not expected to be a problem.
Dutchman Summerville scored 21 goals in all competitions last season as Leeds missed out on promotion with defeat to Southampton in the play-off final.
