Juventus' Simone Zaza celebrates after scoring.
The Hammers have been in the market for a new striker all summer, but have so far yet to bring in a new goalscorer as speculation continues over the futures of Diafra Sakho and Enner Valencia.
However, it does seem that Slaven Bilic's men have found their top target, as Sky Italia's Gianluca Di Marzio reports that talks are ongoing with AC Milan striker Carlos Bacca.
The Colombian, 29, hit 20 goals for Milan last season and is known as one of the top strikers in Europe, but appears to be undecided over whether to make the move to East London in order to join West Ham this summer.
With the situation dragging on, Di Marzio now adds that West Ham are starting to look at possible alternatives should Bacca reject the move to the Olympic Stadium - and they appear to be staying in Italy as they pursue a Juventus striker instead.
It's claimed that, if Bacca doesn't join the Hammers, Bilic will turn his attention back to Juventus striker Simone Zaza, who has been a long-term target for the club.
Zaza, 24, found first-team football hard to come by last season as he was used as cover behind Mario Mandzukic, Paulo Dybala and Alvaro Morata, and may now look to leave the Turin giants in order to play regularly elsewhere next season.
A member of the Italian Euro 2016 squad - though best remembered for his comical penalty miss against Germany - Zaza hit five Serie A goals last season, but 12 goals for Sassuolo during the 2014/15 season shows that he can score when given regular football.
West Ham will still be hoping to land Bacca as their marquee summer signing, but with Zaza lined up as a potential alternative, contingency plans are being made by the Hammers.
