​West Ham have rejected a bid from French club Rennes for striker Diafra Sakho, according to ​Sky Sports.


This comes after the Senegalese forward had an unauthorised medical with the Ligue 1 side on the penultimate day of the summer transfer window, despite a proposed £9m deal having fallen through.


Sakho is reportedly seeking an exit after growing frustrated at what he perceives to be an undervaluation of his services.

The 28-year-old currently earns £30,000 a week, while other strikers in the squad have salaries of between £80,000 and £110,000 a week.


Sky Sports claim that ​Crystal Palace agreed a fee of between £10m and £12m for Sakho earlier this month, but a source close to the deal has suggested that the Eagles might have withdrawn their interest.


​Swansea, ​West Brom, ​Brighton, Bordeaux, Nice and Marseille have also been linked with the former Metz forward.

Sakho has scored twice in 14 ​Premier League appearances for the Hammers so far this season, although he is yet to start a top flight game.

It was reported last week by Turkish newspaper ​Fanatik that Besiktas were interested in taking the striker on loan from ​West Ham until the end of the season.

The Super Lig club were reportedly put off by the Hammers' asking price, but remain interested as they search for a replacement for Cenk Tosun, who recently joined ​Everton for £27m.


Sakho is out of contract at the end of the season, and appears to have set his sights on a departure.
