Manchester United assistant manager Mike Phelan is confident that new signing Zoran Tosic is ready for his debut against Derby.
The winger was expected to be given time to settle in to life in England following his move from Partizan Belgrade at the start of January.
But after impressing in training Ferguson and Phelan have decided to hand the 21-year-old his United bow for the Carling cup semi-final second leg on Tuesday.
Derby take a one-goal lead to Old Trafford from the first leg but despite the disadvantage Ferguson has decided to stick with his youngsters in a bid to get to Wembley.
"Whether it is as a starter or coming on as a substitute against Derby we have not decided yet," Phelan told the Manchester Evening News.
"But Zoran has shown he is capable of blending in. He has done it nice and quietly. Now it is a case of giving him a chance for everyone else to see what we have seen.
"He has really impressed us."
