Jonathan Calleri during his time at Boca Juniors
It's no great secret that the Hammers are in the market for a new striker this summer, with Andy Carroll continuing to suffer injury and fitness problems, whilst Diafra Sakho and Enner Valencia endured underwhelming campaigns under Slaven Bilic.
Some big-name strikers have already been linked with moves to the Olympic Stadium, and now it seems that talks have been initiated to sign a new forward.
Sky Italia's Gianluca Di Marzio reports that West Ham have opened negotiations to sign Argentinian striker Jonathan Calleri, in what may be something of a complicated deal.
Calleri hit 16 goals in 41 games for Boca Juniors to make a real name for himself, before joining Uruguayan team Deportivo Maldonado in a bizarre investor group deal, but has since been sent out on loan to Sao Paulo in Brazil.
Another 12 goals in 24 games have seen Calleri continue to impress in South America, and it seems like only a matter of time before he's snapped up by a club in Europe - even though his contractual situation is somewhat unclear.
Third party rules in the Premier League mean West Ham would have to buy Calleri's registration outright from the investment group which owns his contract, but with his loan deal at Sao Paulo ending later this summer, West Ham could strike a deal - and Di Marzio believes talks are underway to lure Calleri to London.
