Mason Greenwood’s charges of attempted rape, assault, and coercive control have all been dropped.
Last January, the 21-year-old was arrested. He was scheduled to go on trial in November.
The withdrawal of key witnesses and the discovery of “new material” were factors in the case being halted.
“We have a duty to keep cases under continuous review,” a Crown Prosecution Service spokesman said.
“In this case a combination of the withdrawal of key witnesses and new material that came to light meant there was no longer a realistic prospect of conviction. In these circumstances, we are under a duty to stop the case.
“We have explained our decision to all parties. We would always encourage any potential victims to come forward and report to police and we will prosecute wherever our legal test is met.”
While Chief Superintendent Michaela Kerr, Greater Manchester Police’s Head of Public Protection, said, per Manchester Evening News: “The investigation team has remained in regular contact with the legal team, providing any updates of note, and so understand the rationale for the discontinuation of proceedings at this stage, and that this decision has not been taken lightly.
“Despite the media and public’s interest in this case, we have decided not to comment on it in any further detail.
“I would, however, like to use this opportunity to reiterate GMP’s commitment to investigating allegations of violence against women and girls and supporting those affected, regardless of their circumstances, throughout what can be a hard and upsetting time for them.
“An ever increasing number of officers are receiving specialist training and the force is more consistently utilising tools, available via the criminal justice system, to keep people safe and care for victims.
“If you feel you are or might be a victim, please don’t let this case put you off asking for help.”
In 2018, Greenwood made his Manchester United debut.
Prior to his arrest in January 2022, he scored 35 goals in 129 games.
Greenwood has also appeared for England once, in a 2020 UEFA Nations League match against Iceland.
