The UK Sun reports that Mason Greenwood told his friends he would never play for Manchester United again.
In February, the charges of rape and assault against Greenwood were dropped.
However, the United have since started their internal probe, delaying the player’s comeback to the pitch.
The 21-year-old forward was expected to join up with Erik ten Hag’s squad after the charges were dropped and he has become frustrated at the lack of progress.
For now, Greenwood has not been allowed to return to training with the Red Devils, despite still earning £70,000 per week.
His current contract at Old Trafford will expire in the summer of 2025.
