Napoli winger Piotr Zielinski rejected an approach from West Ham in the final days of the summer market.
Il Corriere dello Sport says West Ham made a firm move for the Pole, but the winger was reluctant to leave Naples.
Hammers boss David Moyes had been keen to add an attacking midfielder last month.
Lazio also made an attempt for Zielinski, but was met with the same response.
