Jhon Duran, a teenage Colombia striker, has joined Aston Villa from Chicago Fire in a £18 million deal.
Duran, 19, has eight goals and six assists in 28 appearances for Chicago.
Villa will pay £14.75 million for Duran, who has three Colombian caps, plus a potential £3.3 million in add-ons.
He is Unai Emery’s second signing at the club, following the £13.2 million signing of full-back Alex Moreno from Real Betis earlier this month.
Following the departure of Danny Ings to West Ham, the forward will compete for a starting spot with striker Ollie Watkins, who has five goals this season.
Villa are 11th in the Premier League after winning three of their last four games.
