That photo could be explained a number of ways but the tape, assuming it is verifiably him, is totally different. It is toxic and imo no amount of benefit he could bring on the pitch is worth what united are likely to lose in reputation and the associated publicity playing him would attract.
In the vast majority of other cases of allegations of sexual assault involving footballers that are widely public, such the Mendy case, there is no publicly available evidence, save for the eye witness accounts of the accusers. This makes any public statements questioning the circumstances around the events to be hugely risky and genuinely unfair to the accused, especially after a finding of not guilty. That tape, what is in it, and the fact it was so widely disseminated, unquestionably distinguishes Greenwood from those other cases - on the basis, as I’ve said, his identity isn’t in dispute. I’d be amazed at any competent legal professional suggesting otherwise.
That isn’t to question his guilt at the crimes he was accused of, because that manifestly hasn’t been established, but that recording provides a shield for groups who campaign against domestic violence and abuse to speak with far more stridency on this particular subject around Greenwood without any real fear of legal consequences, assuming they choose their words carefully. In fact, they would arguably welcome a claim for defamation from Greenwood, in relation to those carefully chosen words. How would he frame an argument around loss of reputation and/or lack of truth, if that was him in the tape? I’m not sure where you’d start with that.
From a tactical point of view, in terms of promoting their cause, this would be the motherlode for those campaign groups and would surely be recognised as such by them and exploited accordingly. The questions that tape raises are not ones that are likely to be comfortable to answer or ones that anyone would be well advised to put themselves in a position to. It could be cross examination dynamite.
For a club whose nose for PR is so widely held up, the decision to play him (assuming that is their intention) seems incredibly foolish imo, so much so that I’ll believe it when I see it. I think they would most likely be setting themselves up for a PR disaster that they cannot manage their way out of - and the current narrative may simply be the club sounding things out to establish how the land lies, the answer to which will be ‘not favourably’. They are best settling his contract and wishing him all the best. Simply put, and imo, that tape is worth more than whatever sum of wages and compensation are left on his contract.
