There’s an awful lot of rumour going around - much of it from dubious sources, as you say, and most of the remainder from those with an incomplete knowledge of the situation.
Yes, there is absolutely a possibility that the stadium will not be ready by 28th October. We simply don’t know yet how extensive this problem is and how long it will take to put it right. It could be a matter of months or it could be a matter of weeks. I simply wanted to remind those involved in the discussion that the one option that appears to have been ignored altogether is that the stadium will be ready in time after all.
