Zoran Tosic is set for a surprise introduction to English football with Sir Alex Ferguson lining him up to make his debut in the Carling Cup semi-final second leg against Derby on Tuesday. The Serbian winger, who was unveiled last week following his move from Partizan Belgrade, was expected to be eased into the United first team. The 21-year-old was not supposed to be introduced for another six weeks with Ferguson wanting to ensure he was prepared for the physical demands of the Premier League. But the United manager has had a rethink and Tosic now looks likely to play some part in the match, which Derby lead 1-0 after the first leg.
