This is part of a wider problem. Very few incidents of rape result in charges. If they are charged, the conviction rate for rape is actually 75% (not sure how that compares with other offences but it's higher than most of us think it is). However rich people accused of rape can afford top legal teams so their chances of conviction are lower.
The problem is that money is thought to be more important than women's safety in top level football. Benjamin Mendy (recently found innocent of multiple charges of rape) was out of contract at Manchester City. They didn't need him. He's not played competitively for a couple of years so there was no pressure to keep him. Utd clearly did want to keep Greenwood and it was only due to the opposition that they decided he wouldn't return to the 1st team. I personally don't think Greenwood will find another team in England but I'll bet that's more because he has a bad attitude and hasn't played competitively for nearly 2 years. He probably won't go to Saudi Arabia as even he realises that a man who persisted in holding illegal parties in the pandemic probably won't manage to stay on the right side of the law in Saudi Arabia.
Another Premier League club have continued to play an unidentified player even though he has been on bail for rape for over a year. (There are rumours about his identity but legally he can't be named unless he is charged). The other day Nottingham Forest signed a player accused of rape in Argentina.
I wish this was an isolated case but it isn't. In the UK, what happens is up to the clubs unless a player is prosecuted. Apparently, in the USA, the equivalent bodies to the FA would step in and sanction players.
