West Ham are in talks to sign Sao Paulo striker Jonathan Calleri.

Lancenet says the Hammers are keen to add a forward to their squad ahead of this summer's move to the Olympic Stadium.

Before joining Sao Paulo on loan in January, the 22-year-old scored 16 goals in 41 appearances for Boca Juniors last season.

And Calleri has continued his exploits at the Morumbi stadium, bagging 12 goals in 23 games
