West Ham United are reportedly preparing a bid for Polish striker Piotr Parzyszek.

Sam Allardyce has already added Italian duo Antonio Nocerino and Marco Borriello to his squad this month, but the Hammers boss is keen to bolster his attacking options further.

According to The Express, Allardyce has switched his attention to Parzyszek after admitting defeat in his pursuit of Leeds United captain Ross McCormack.

Parzyszek, 20, currently plays for De Graafschap in Holland and is the top-scorer in the Eerste Divisie.
