The main issue for me is that he's very young. It's proven that adults think with the prefrontal cortex, the rational part of the brain. That isn't fully developed until age 25. The teen brain thinks with the amygdala, which is the emotional part. If you were to go into a typical secondary school in the UK you would be fecking shocked at what social media has done to the sexual opinions of boys (and girls) up and down the country. This is in no way excusing it, rather to highlight just how young Greenwood is and his path to rehabilitation is strong with the correct support network (whether at United or externally).
The other issue is that this is a problem affecting - most likely - every single team in the league, as highlighted by the
recent story on the BBC. Not bringing Greenwood back would not be a moralising decision but one purely based on PR, as we (and likely most other teams) are playing players that are or have faced similar claims without public knowledge. If we were to not bring Greenwood back based on public opinion, I would at the very least hope we took the vanguard in combatting the issue across the league. Otherwise, it'll just be a PR stunt without forethought of the actual reason why he's not playing for United (i.e. we don't want to field sexual abusers).
On top of it all, the victim has chosen to start a family with him and has decided to publicly support him at Getafe. She didn't have to do that and I think it's particularly telling.
