West Ham are making a new offer for Napoli midfielder Piotr Zielinski.

Il Corriere dello Sport says West Ham are ready to up their offer for Zielinski.

The Hammers' initial approach of just over £20m is believed to have fallen well short of Napoli's valuation of the Polish international.

Manager David Moyes' side are set to return for the midfielder after completing a big-money move for Gianluca Scamacca, who has signed a five-year deal after joining from Sassuolo.
