West Ham have rejected a £35m bid from an unnamed Chinese club for forward Marko Arnautovic, according to Sky sources.

West Ham signed the Austria international for £20m from Stoke in the summer of 2017 and have him under contract until 2022.

The Hammers say Arnautovic is not for sale and that, in any case, "£35m would be nowhere near enough for such a key player".

The 29-year-old scored 11 times last season and has eight goals in 17 appearances this term, including a double in last week's 2-2 draw against Brighton.
