Manchester United boss Sir Alex Ferguson confirmed 19-year-old midfielder Jesse Lingard and Republic of Ireland Under-21 international Robbie Brady are set to start United's first pre-season game against AmaZulu in Durban on Wednesday.
"It is always a difficult one," said Ferguson.
"Obviously the priority is to get the fitness of the experienced players correct. But there will be young players involved in each game because I don't have the full quota with me.
"Jesse Lingard has been doing well and Brady will play at left-back because even though he is an outside left, we feel he has the quality to develop into a left-back."
