I haven't seen that episode of the United stand but any episodes I have seen they has said several times he has no sources at united and he talks about what's in the news.
If you watch his episodes he uses a lot of 'if' & he creates scenarios of possible things that 'could' have happened in his mind. Up to anyone that has watched it to form their own opinion.
The basic jist is, goldbridge is like any other fan, knows little of what's going on but talks about it. He's just had the foresight to set up a channel & make some money out of it.
