This has always been 50/50 at best whether it goes ahead or not but this rumour doesn't hold water to me. Couldn't resist the pun, sorry.
Even the thought of building at BMD would raise these questions, let alone be well down the road in terms of design and consultation.
Of course, it this eventually fails, it will be due to funding but to fail on this specific reasoning regarding the cost of foundation work, then it would truly beggar belief.
If that was the case then the whole lot of them, Moshiri downwards, should immediately depart the club en masse if they had any self-respect, let alone respect for the club and its supporters.
There would be no need to close the door on their way out either. If this doesn't come to fruition within the next five years, then we are never seeing a new stadium in any format and the club is effectively confirmed as a spent force.
