West Ham United are struggling to convince Heerenveen striker Bas Dost about a move to London.
The Hammers have launched a £7 million bid for the young Dutchman.
"West Ham is a very nice club," said Henk Nienhuis, the agent of Dost, to Algemeen Dagblad.
"But there are currently over three serious candidates, with VfL Wolfsburg still by far the number one. In our opinion there does not need to be one more."
