Aston Villa have signed teenage Colombia striker Jhon Duran from Chicago Fire in an £18m deal.
Villa will pay £14.75m for Duran, who has three caps for Colombia, and a potential £3.3m in add-ons.
He becomes Unai Emery's second signing at the club and follows the arrival of full-back Alex Moreno for £13.2m from Real Betis earlier this month.
The forward will compete for a starting role with striker Ollie Watkins, who has scored five goals this season, after the departure of Danny Ings to West Ham.
Villa are 11th in the Premier League having won three of their last four league matches.
