You'd just play Bing in the forward ruck role with Marshall.Matthew Lloyd was asked that once and said he reckons they could - that Bing is your lead up CHF type and Winx is the stay at home FF.
Having said that, I'm not sure how it would work. Unless Bing was a CHB / CHF swingman.
You're right that another club could offer him more than we will be able to.
Our hope is the romance of playing with his brother at the club they both grew up adoring somehow outweighs the financial aspects. When he comes OOC we will be right in the window so hopefully that sways him. One can dream
No doubt it would work IMO.
