West Ham have signed Argentina striker Jonathan Calleri on a season-long loan from Uruguay's Deportivo Maldonado.
The 22-year-old represented his country, who were eliminated in the group stage, at Rio 2016 and will arrive in London next week.
Calleri spent the first six months of the year on loan with Brazilian side Sao Paulo and was top scorer in the Copa Libertadores.
"Unfortunately for him, but good for us, Argentina were knocked out of the Olympics this week, so he should be here with us pretty soon, depending on the work permit."
West Ham open their Premier League campaign away at Chelsea on Monday and Bilic says he is unlikely to add to his squad.
