Crystal Palace have reportedly had an £11m bid for midfielder Cheikhou Kouyate turned down by West Ham United.
Kouyate is believed to be surplus to requirements at West Ham this summer, and Palace have been strongly linked with a move for the central midfielder in recent days.
According to football.london, Palace made an opening offer of £11m for the 28-year-old, but West Ham quickly rejected the bid as they want closer to £15m.
Kouyate, who has a contract with the Hammers until the summer of 2021, has scored 15 times in 147 appearances for West Ham since arriving from Anderlecht in 2014.
Palace have also been linked with a move for Kouyate's teammate Michail Antonio ahead of the 2018-19 campaign.
