As I understand it he wants to have the conviction over turned based on him saying that she did consent to him coming in a room where she was having sex with another guy, a room that he wasn't invited to, a room that he only knew the girl was in because his friend had text him "something to the effect of having met a girl" a room where he lied to hotel staff to get the key, and a room he left via a fire escape rather than walk out the main doors.
So he wants to turn it into a he said she said thing.
They hope that some evidence is going to come from Face book because they say it's suspicious that a girl who has just been raped goes and spring cleans her face book account deleting messages around the time of the offence. (their hope is that she was boasting about shagging a footballer).
He, and his family are just grasping at straws and trying to make the girl out to be some sort of drunken liar that gets drunk and has sex all the time.
They suggest that a note written at the top of the page in the police report insinuating that he may he a rapist was clearly written first. so that the police clearly never gave them a chance. (rather than notes being written in any order.)
If this mythical evidence did magically turn up I'd still think it was a pretty crappy thing that he broke into a room he knew people were having sex in just to get involved.
Even in the unlikely event that his rape conviction is overturned, the kind of person that interoperates a text messages saying "I've met a girl and am going back to the hotel" as go get yourself a key card and join in the fun is not a good role model, and should not be in a prominent position anywhere in society, and should never even entertain the idea that they should be worthy to think about playing for their national team...
(I imagine that if anyone knew what that text message actually said (instead of just something about a girl) that it's only serve to incriminate him more!)
