Zoran Tosic and Adem Ljajic are relishing the prospect of life at United.
The
young Serbs agreed to join United from Partizan Belgrade last week,
with Tosic joining immediately and Ljajic spending 2009 at Partizan
before moving to England next year.
Left-winger Tosic, 21, is already aiming high and hoping to force his way into regular first team action post-haste.
"At the beginning it was a dream to play somewhere like United but now it is a reality, one I am very happy with," he told the official UEFA website.
"I want to become a top player at United and not waste the opportunity of being a member of the greatest football family. It is great feeling, but now I must think about working hard.
"The presence of Nemanja Vidic will be a great help as I know him from the national team. I am full of confidence, will learn quickly and hope United can count on me very soon."
While 17-year-old striker Ljajic will have to wait a year longer than his compatriot, he is already planning for his arrival at Old Trafford in 12 months' time.
"It has all happened so fast for me," he said. "I am only 17 and have had some dreams in the past but can now have one more: the United shirt.
"However, I will spend the next year learning more at Partizan and I will be ready for Old Trafford next January."
