Indeed, the Hammers have added yet more pace to their ranks - with the 28-year-old Fenerbahce forward famed for his speed on popular football game FIFA.
It’s unclear how that affects the rest of West Ham’s strikers but the door could be open for Nikica Jelavic to leave the club, possibly also on loan.
And Watford man and fellow Nigerian Ighalo has congratulated Emenike on the move.
West Ham now boast Andy Carroll, Diafra Sakho, Enner Valencia, Jelavic and Emenike within their strike force, although Carroll, Sakho and Valencia have all suffered injury problems this season.
Both the Hammers and Watford are still in the draw for the FA Cup after this weekend’s action, although West Ham have to play a replay against Lierpool, with the Hornets having won outright.
