I think Wrexham being a reasonably sized club, and one who spent a disproportionately amount of time in non league in recent years compared to their history, very much counts in their favour whereas Salford are nothing more than a scaled-down English version of RB Leipzig.
It’s about far more than money. By the sheer nature of a club sacking their manager, it creates a vulnerability for the next man which, rightly or wrongly, doesn’t apply to IE while FV are in charge.
