West Ham have re-entered the transfer market for Napoli striker Manolo Gabbiadini, according to a report.

The Hammers have been desperate to bring in a proven spearhead throughout the summer, as doubt surrounds the futures of attacking duo Enner Valencia and Diafra Sakho.

Italian publication Calcio Mercato now claim that Gabbiadini is back on manager Slaven Bilic’s shortlist, and the Hammers have readied a bid worth £21million.

West Ham signed Andre Ayew from Swansea on Monday for a club-record £20.5million but the Ghana international is more comfortable on the flanks and is not an authentic line-leader in the mould of Gabbiadini.

Sky Italy journalist Gianluca Di Marzio had claimed on his website in June that the Hammers were one of a number of Premier League clubs eyeing a swoop for the 24-year-old.

The Italy international is believed to be open to a move away from the Italian outfit after he spent much of last season on the bench and featured in just 22 league games all season.

Gabbiadini was left out of Italy’s provisional squad for Euro 2016 by Antonio Conte following his season on the fringes.

The former Sampdoria striker has over three years remaining on his contract, and has scored a ratio of one goal every three games in all competitions for Napoli; finding the back of the net 20 times in 60 appearances.

Bilic will have to do some convincing though, as the sale of Gonzalo Higuain could mean that Gabbiadini will be given more of a first team chance at the Stadio San Paolo.

In the latest West Ham transfer news, the Hammers have confirmed a second left-back deal within 24 hours.
