I think the most likely scenario is the executive team has overestimated our current pull when agreeing targets with Moyes and is getting rebuffed without being ready/able to offer more £ to change one or two minds.
We must be near the point where Moyes just insists they implement whatever his back-up plan is eg Soucek, Brownhill, Coufal (possibly even Harrison heaven help us) or similar all improve the squad and at least a couple would start so go get them today then carry on chasing a whale or two until the window closes.
It isn’t ideal and it would not really move us forward unless we actually land one or two top targets late but Moyes is pragmatic and competitive so he won’t want to mail it in for a relatively favourable first 3 games before the window closes IMO.
