You understand there are levels of transgression, right? MG and his partner have already admitted, between the statement and her social media feed, that he did things wrong in the sense of personal ethics, including cheating on and verbally abusing his partner whilst they were together. In terms of his conduct at the club, there have already been lots of small news stories about past bullying or other infractions. These haven't been detailed officially in their specifics as a balance sheet because they weren't things he was being prosecuted for, as well as for reasons you can speculate on (would it breach confidentiality of other individuals; would it harm the reputation of his partner and expose her to some degree of social media ordure; there are., of course, other explanations) but MG clearly had to rebuild his relationship with both the club and his partner, regardless of whatever else may have occurred. Again to this 'whatever else', he might be guilty of one or more charges; the point is only that we now don't have a full enough picture because previously conclusive material has been called into question, and two separate bodies have consequently ruled that the evidence points in his favour in respect of specific Criminal charges -this is literally all that's being brought up. There's a reason why jury trials and the contemporary legal system for all its faults, has evolved and why evidence is supposed to be entered, and examined by both prosecution and defence in a trial before a conclusion is reached.
If people are asking for him to be let go on the basis of what has been conceded by all parties or leaked (though not officially corroborated by the club) about his previous training ground conduct, then that's another discussion. However, the claim that his position was untenable -and why he shouldn't be allowed to play for any club., de facto, because of the now quasi-autonomously social media pressure campaign- rests specifically upon an allegation or allegations which both the CPS and the club, working independently, have found doesn't/ don't sufficiently bear the weight of scrutiny, being actually unequivocally true. True, because the internet, without currently having that extra information, has decided the claims (of attempted rape and assault) are true. If subsequent allegations around sexual assault emerge, or new facts about this case are made clear to the police/CPS, and are tested either in court or if MG makes a statement admitting to the initial allegations, then I don't think anyone here defending the position of 'innocent of those specific crimes until proven otherwise' would advocate for his staying at the club or indeed for joining another club in the future without some punishment and rehabilitation period first at the very least.
