The 21-year-old's agent Ondrej Chovanec has revealed his client would prefer a move to West Ham over Swansea City.
He told the Daily Mail: "Swansea will not happen.
"Swansea have already bought Bony and I don't think they will buy another striker.
"If they try to loan the player then the answer will be no, it's simple.
"West Ham are a very good club and Vydra would fit there very well.
"I have spoken to West Ham but not for two weeks now, the ball is in their court."
