West Ham are close to signing Jonathan Calleri on loan, according to a report.
The Sun claim the Argentine striker is set to join Slaven Bilic’s team from Brazilian side Sao Paulo.
This comes after Jack Sullivan, the son of Hammers co-owner David Sullivan, claimed on his personal Twitter account on Wednesday night that the 22-year-old has agreed a move to the east London club, with the move now subject to a work permit application next week.
Sullivan junior did not disclose whether it would be a permanent or loan deal but the Sun report suggests a temporary deal is now in place.
Calleri has been likened to West Ham fans favourite Carlos Tevez after an impressive spell of form in his home country, and is becoming increasingly known for skill and technical ability.
Bilic has been in the hunt for a proven goalscorer all summer, and has been linked with the likes of Christian Benteke, Michy Batshuayi, Alexandre Lacazette, Theo Walcott as well as a sensational east London return for Tevez.
West Ham are now hopeful of signing Carlos Bacca in addition to Calleri and 20-year-old Ashley Fletcher, who joined from Manchester United earlier this summer.
Calleri, who is yet to make any Argentina appearances, has attracted Premier League interest since scoring 21 goals in 53 matches for former club Boca Juniors.
He has since been loaned to Sao Paulo for six months via Uruguayan club Deportivo Maldonado and 10 matches for the Brazilian side in 2016 have yielded an impressive eight goals.
However, any deal for the youngster will be complicated as any buyer wanting to negotiate a permanent deal would have to buy out his third party investment group.
In other West Ham transfer news, Crystal Palace have joined the race to sign £15million-rated striker Diafra Sakho.
