West Ham chief Karren Brady has warned Marseille they must pay big for Dimitri Payet.
Brady wrote for The Sun: "If Marseille want a bargain they ought to try Roman Road market.
"They should know that Dimitri Payet, skilled enough to play for Real Madrid as well as West Ham, isn't going cheap, should we decide he can leave at all.
"Chelsea are in the same boat and holding firm like us.
"My chairmen and the manager keep repeating they want to keep Payet.
"I can assure you they won't be bullied into agreeing anything that is not in the best interests of WHU."
