Carlos Queiroz was hugely influential in Manchester United's capture of Angola star Manucho Goncalves.
The 24-year-old Angolan international striker, who has scored twice in 10 appearances for his country, has agreed personal terms and will join the Club in January on a 3-year agreement. An application for a work permit will be made in due course.
He was top goalscorer in the last two seasons of the GiraBola, finishing with 16 goals for Petro Luanda in 2006 and 15 goals this year. Manucho will be part of the Angolan squad for the African Nations Cup in January.
Sir Alex Ferguson is delighted by the new arrival, saying: "We have had Manucho here for a 3-week trial and have been impressed enough to offer him a 3-year contract.
"He is a tall, agile and quick forward and through contacts that Carlos [Queiroz] has was brought to our attention around six months ago."
