West Ham have opened talks to sign Argentine forward Jonathan Calleri, according to The Mirror.
The 22-year-old found the net 16 times in 41 appearances for Boca Juniors before going out on loan to Sao Paulo.
Slaven Bilic has been following the striker for some time now, and is believed to try lure the player to the Olympic Stadium when his loan move is completed.
Is this the striker which the Hammers need to buy this summer?
