I would not see a realistic offer for any of them until the jan window after a consistant number of games.
By that time if the take over is real and moved on or close to concluding id expect the owners to vito it. If its close to a done deal now again they could stop any sale or pull out.
The upshot right now none of us have a clue as we don't know what stage the sale of the club is at. The interested party could be a storey to try and push others to make a bid.
Personally after the bollox Top has said over the last few years i,ll believe nothing until it happens. Other than we know financialy we are in the shite.
