West Ham United are set to complete a loan move for the Argentine striker.
Calleri impressed on loan to Sao Paulo
The Argentine striker will reportedly join the Hammers on loan, despite interest from Europa League winners Sevilla.
Calleri, who began his career at Boca Juniors, is said to have sought the advice of former United striker Carlos Tevez before agreeing his move to the Olympic Stadium.

An investment group was behind the 22-year-old's January switch to Uruguayan side Deportivo, for whom he is yet to play after spending the past six months on loan to Brazilians Sao Paulo, where he scored 12 goals in 17 appearances.
According to the Guardian, West Ham's pursuit of the uncapped front man will not signal the end of their striker search, with Toulouse's Wissam Ben Yedder emerging as a target.

However, Slaven Bilic's side are said to face competition from Premier League champions Leicester City to land the former France Under-21 star, who scored 23 times in all competitions last term.
Despite spending his entire career in South America, Calleri can transfer freely to England as a holder of an EU passport.
