This is where I disagree. Nobody knows more about the detail than the people trying to invest, and believe me, they will question Donald and his activities in far more stark terms than anyone. There is no hiding from the situation, it's just fact. They know where money is and what has gone in and out for the last 18 months and beyond.
What I would say - and this has been my point from the start on this matter - is that Donald objectively, factually, owes the club more than £20m, or did so with the last known information. There is zero doubt that this will have a bearing on the investment, as anyone coming in will want assurances about when that money (and any other cash outstanding) is coming back. He will be losing control of the schedule of repayments at bare minimum. At worst (for him) they could demand it is repaid immediately.
The most important part is that he has done nothing wrong legally, but there is a huge financial issue there that in some way will need to be addressed. The fans writing stream of conscious interpretation stuff on Facebook don't have any bearing on whether anyone would invest, in fact fan pressure on Donald is likely what the Americans want in order to tighten the screws on him.
