Man Utd boss Ferguson: Tosic will play in Cup
"I'm not risking the League campaign for the League cup and even though we are so close to the final that doesn't matter. I think the young boys will do well," said Ferguson.
"Derby will bring 12,000 fans, it'll be a great atmosphere and it's the perfect stage for youngsters like Danny Welbeck, Rodrigo Possebon, Darron Gibson, Rafael Da Silva, Anderson and Nani.
"Tosic will also be involved if his work permit is through. I may not start him - it depends on the fitness of the other players."
Fergie's also promised his youngsters that if they reach the final they'll be given their chance at Wembley, probably against Tottenham, who are favourites against Burnley.
