Stoke City are demanding near £30m to sell Marko Arnautovic.
The Mirror says Stoke have rejected a second offer of £20million from West Ham and want closer to £30million for Arnautovic.
They feel the Austrian forward is worth that amount because he has three years left on the contract he signed last summer.
Arnautovic, 28, is trying to force a move from Stoke by slapping in a transfer request, but the Potters are adamant he will only leave on their terms.
