West Ham must up their bid to sign Napoli striker Arek Milik.
The Hammers are said to have bid £6.3million for the Poland superstar as David Moyes targets a replacement for Sebastien Haller, says The Sun.
And Napoli are keen to offload the 26-year-old this month with his contract set to expire in the summer.
Milik is yet to feature for the Italian outfit this term having been omitted from Gennaro Gattuso's Serie A and Europa League squads.
Italian journalist Ciro Venerato has stated Milik could end up at the London Stadium, but only if they improve their bid.
Quoted by Spazio Napoli, he said: "Milik can go to Marseille, the French side are a club where the Pole can land. Napoli continue to ask for more than €9m (£8m) and there's also a problem with the percentage of resale.
"There's also a chance he'll go to West Ham, a chance offered by the agent."
