Chilean Angelo Henriquez says a move to Manchester United would be a dream and that he expects to move to Old Trafford when he's older.
The 17-year-old, currently at Universidad de Chile, has spent two spells training with the 18-time league champions.
An agreement between the two parties means United have first refusal on Henriquez in 2014.
Henriquez said: "I am still a player of Universidad.
"They have told me that they would take me when I am older and have more experience.
"It would be a dream come true [to move to United] but I have to keep working hard."
United are keen to bring a new young breed into the squad with the likes of Paul Scholes, Ryan Giggs and Rio Ferdinand coming to the end of their careers in Manchester.
As well as Henriquez, United have been tracking Steven Defour and Javier Pastore and are expected to spend big this summer on a squad in need to re-energising.
