West Ham have snapped Emenike up until the end of the season on a temporary move, but they have already agreed a price with Fenerbahce to make the switch a longer term one.
The Hammers did a similar deal for Manuel Lanzini, when they signed him on a loan deal at the start of the season.
Emenike has been brought in by Slaven Bilic to increase his side’s attacking threat.
West Ham currently have a number of strikers on the treatment table, and Emenike is likely to have a prominent role to play, as a result.
Bilic knows the striker well, and he will compete with the likes of Diafra Sakho, Andy Carroll and Enner Valencia for a place up front.
According to a report in the Daily Mail, Emenike’s arrival could be bad news for Nikica Jelavic, as the Croatian forward could be forced to leave Upton Park.
