The Sunday Express says just 48 hours after helping United win the FA Youth Cup, Morrison appeared in court with his Old Trafford career on the line.
Morrison, 18, pleaded guilty to criminal damage at Salford Magistrates' Court in the knowledge that he was already the subject of a 12-month referral order after being convicted of witness intimidation.
The wayward teenager has been told in no uncertain terms that he cannot afford any more transgressions if he is to fulfil his enormous potential.
A United insider said: "Everyone, the manager included, has leant over backwards to try to give Ravel every opportunity to succeed here. Without question he possesses exceptional talent but he has received so many warnings over his timekeeping and his attitude.
"He has so much to lose because, providing he focuses on his football, nothing is unachievable for Ravel. If he steps out of line again, he will be on his way out of the club despite his potential.
"If he continues to progress as a footballer, the United fans could see a lot more of him next season."
