Nigerian striker Emmanuel Emenike is flying into London to undergo a medical at West Ham United ahead of a loan move to Upton Park, sources have told ESPN FC.
West Ham have agreed a deal with Fenerbahce to take Emenike, 28, on loan for the rest of the season, with the view to a permanent move.
The potential move had been held up because it needed the agreement of Fenerbahce and Al Ain as the Nigerian had been on loan at the latter.
Al Ain agreed to cut short his season-long loan deal to allow him to return to Fenerbahce so that he could then make the switch to West Ham.
West Ham boss Slaven Bilic is looking to add to his striking options before the close of the transfer window with Andy Carroll and Diafra Sakho on the sidelines.
Sources have told ESPN FC that Emenike has already agreed personal terms with West Ham and should he pass his medical he will become their second signing of this month's transfer window after Sam Byram's arrival from Leeds United.
In October, Emenike, who was top scorer as Nigeria won the Africa Nations Cup in 2013, announced his retirement from international football.
