West Ham wanted to sign Turkish international Burak Yilmaz, on loan from Galatasaray in January, according to Haberturk.
It was reported that the Hammers made approaches to both Yilmaz and Emmanuel Emenike, as they were keen on improving their attacking options to bolster the squad and to provide cover for injuries.
The Emenike signing did go through before the transfer window ended and although the offer for Yilmaz was a loan deal, West Ham were willing to include a £700,000 fee on top of the loan in an attempt to seal the move.
An option to buy was also included in the offer, providing the player performed under Slaven Bilic.
The option-to-buy clause is rumoured to have been around £6.2 million plus add ons, but the deal was not finalised, and the Hammers missed out on their man.
Yilmaz, in the following days, did seal a move away from the Turkish club, to Chinese side Beijing Guoan.
