West Ham United have signed Paraguay Under-20 striker Brian Montenegro on a season-long loan deal from Uruguay's Club Deportivo Maldonado.
The 18-year-old began his career at Paraguayan club Tacuary where he made 51 appearances and scored seven goals before joining Maldonado.
He told the club website: "I am a fast player, I like to run at defenders and scare them.
"I am still developing physically but I like to attack."
Montenegro, who featured for Paraguay's Under-20 side at the South American Youth Championship in January, added: "I am very excited to come here and play in England, especially for a club like West Ham.
"I am hoping to get a chance to show the fans what I can do."
