If the two CBs in the hypothetical example are both injured, Godfrey plays alongside Branthwaite. Are you familiar with the squad mate?
You're ignoring the reason the squad is depleted in the first place. We have a big squad, it's just got too many perma-crocks like Delph and Mina, and absolute bums like Tosun who have no interest in playing whatsoever.
The club cannot ignore the financial scenario. It isn't going to be possible to wave goodbye to six players and then immediately stockpile six more. Quantity is going to have to make way for quality - and let's face it, a squad made large with a swathe of rubbish players hasn't got us anywhere this season, has it.
