Zoran Tosic says he has joined the "greatest football family" and believes Nemanja Vidic will help him settle in at Old Trafford.
The 21-year-old Serbian winger also believes he can learn to adapt to the Premier League quickly and hopes to make his debut sooner than Sir Alex Ferguson hinted when he suggested a February bow.
Tosic's rise to prominence began after he lit up the European Under-21 Championships in 2007 with his performances in the Netherlands during that tournament earning him a move to FK Partizan Belgrade.
United noticed him while scouting former Partizan striker Stevan Jovetic and followed his progress as he earned the first of his 12 full caps for Serbia.
"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 said. "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," he added. "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."
