The club has the perfect excuse to back away from him without looking as though they are backing down given that they have simply let him train with the first team so all they have to say is that, after two plus years away from top flight playing, he wasn't fit enough/not a good fit with the current line-up/they already have enough talented strikers or any variation on that theme.
The ironic thing for me is that had he reacted differently to this and not carried on being the arrogant vermin that the act itself showed him to be, he could have managed this very differently. Say he came out of prison and immediately put his energies into a campaign of 'I was wrong, rape is wrong, please let me make amends' and gone with that message rather than his ridiculous insistence he did nothing wrong - does he, and his ludicrously deluded girlfriend and sister actually listen when he talks, does any part of what happened really not seem astonishing, disgusting and barbaric behaviour to them? - things might have been very different. He could have been the poster boy for prisoner rehabilitation; staunchly anti-rape and against violence against women, even against sexism in football, with donations to charities for the victims of rape, damages paid to his victim and the calling off of all the trolls 'supporting' him by attacking her - even if he didn't mean a damned word of it - it might have worked out better than this but he is another leopard who can't change his spots and everything about the attack that showed him for animal he is has snowballed into something that was far bigger than anyone could have imagined and so much of it against him - I am delighted!
