Juventus coach Max Allegri has put Joseph Nonge on notice.
Allegri says Ngonge is the next young player he plans to bring through.
The Juve coach was asked about January market plans after victory over Roma.
But he replied: The only way we can improve our squad is by working in training.
"We have young talents who are growing rapidly and the next I hope we'll see in the senior squad is Joseph Nonge, who needs to be straightened out a little bit, but certainly knows how to play football."
Belgian Ngonge, 18, is currently playing for Juve's NextGen team in Serie C.
