West Ham are locked in talks with Burnley for striker Andre Gray.
The Daily Mail says Gray is in the middle of a contract dispute with the Turf Moor side and is unwilling to extend his current deal, which runs out in summer 2018.
Sean Dyche is not willing to let one of Burnley's prized assets depart on a free transfer and will look to sell him if he does not put pen to paper on fresh terms.
And Slaven Bilic is ready to exploit the situation as he looks to add firepower to a side that struggled in front of goal last season.
The 26-year-old impressed during his first ever Premier League campaign, scoring nine goals in 26 starts for a side expected to struggle to stay up.
