Manchester United have completed the signing of teenage forward Angelo Henriquez from Universidad de Chile.
The 18-year-old Chilean moves for an undisclosed fee, but is likely to remain with Universidad de Chile for the next season to continue his development.
Henriquez graduated to Universidad de Chile's first-team in the past 12 months, and hit 11 goals in 17 games as the Chilean side won their first ever Copa Sudamericana.
United have been tracking Henriquez for the last three years, and secured a first-option agreement with the South American side in 2009.
Ferguson decided to exercise that option this summer, after the 18-year-old impressed United's scouts with his rapid progress.
Speaking to United's official website, Ferguson said: "Angelo has made a tremendous impact on the game in his short career so far.
"His pace is a great asset and he reads the game really well for someone of such a young age.
"We have a proud record of developing young talent and Angelo fits the profile of a United player - skilful, attacking and someone who plays the game with real flair."
After the deal was completed, Henriquez took the opportunity to reveal his joy at signing for one of the most famous clubs in world football.
"I am thrilled to be joining the biggest club in the world," said Henriquez. "Manchester United is a great team, and has a great manager."
