Listening to the Forum, I got the impression that Hallett does not want any further investment, and that the Club does not need any further investment. I haven't gone back over the forum but I think he even said that in a reply.
He accepts that he can only get us into the Championship and, maybe, remain there, and that is his aim in taking over the Club. This will be because of the income that the refurbished grandstand will generate in the future, and why he has spent his investment in that area in order for the Club to be sustainable in the future.
Therefore there is no need for further investment at this time (and this would also dilute his share of PAFC).
In my view, the only time anyone could put further investment into PAFC will be when Hallett sells the Club to someone (the right person) who he thinks will be able to take the Club further up the ladder.
I cannot see how we could go further without investing money into the Club in order to achieve further success. And I don't mean putting money into the playing staff per se, but investment into the Club in order to maintain future returns as well as the here and now.
As an example, if the limited capacity of the ground became a problem for the Club, with more people wanting to attend than there were seats, or standing capacity, then extra revenue would be required if phase two, or similar, were to be completed.
I don't think this will happen, the investment/return would not be a viable proposition, but I use this as an example only, to show that any further investment would need to be put towards making future returns rather than directly into the playing staff, which would be counter productive, in my opinion, although it would be lauded by us fans and would get us excited in the extreme, but it would do nothing for the sustainability of the Club, and would be money lost rather than well spent.
We are getting a bit ahead of ourselves at the moment, let us just sit back and enjoy the ride, as and when the investment into the grandstand made by Hallett, comes to fruition, which it surely will in the near future, when this damned Covid gets under control.
