Kouyate, 25, eventually joined the Hammers from Anderlecht in June at around £7 million fee and according to Calciomercato has been the subject of an AC approach.
But a Hammers source immediately knocked back the storytelling ClaretandHugh: “That’s news to us and Cheik is simply not to sale – end of story.
The Hammers goalscorer against Manchester United – who was outstanding as an emergency central defender – is another bargain buy by the club having been scouted by Sam Allardyce to become the first major signing of last summer.
Kouyate’s form has been monitored by AC but the player is very content with life at the Irons and is locked down until 2018.
Calciomercato has reported the Hammers have been approached about a possible summer move but our source said: ” Cheik was desperate for the move to this club and there’s no chance of him leaving in the summer.”
