United is pleased to announce it has reached an agreement with Partizan Belgrade and the players for Zoran Tosic and Adem Ljajic to join the club.
Tosic, 21, will sign with immediate effect and wear the no.14 shirt, while an agreement is in place for 17-year-old striker Ljajic to remain with Partizan for the rest of 2009.
A press conference will be held next week, once the necessary paperwork has been filed with the relevant football authorities.
Sir Alex Ferguson gave his reaction to the signings at his Friday press conference and also confirmed United will not be doing any more transfer business in January.
"Tosic joins us immediately, his work permit is through; Ljajic will join us next year, " revealed the boss. "Tosic is a young wide left player. We like wide players at this club.
"We've been watching him for over a year. Our scout in that area has been telling us about him for quite a while. He's now a regular in the Serbian national team. Hopefully he does well.
"We'll give him time. He's not played since December 10 so he'll need time to adjust and get used to the tempo of our game and also the training.
"That's the end of the transfer business for Manchester United this season. There definitely won't be anything else in January."
