To be fair to Gus too, how many of the players he sold are regulars in their 'once Premiership' teams? That was good business. We're obviously not looking to pay huge money in wages or transfers, hence the investment in development, and injuries played their part this season too.
If OG wanted out, he'd simply go, not "offer to resign". If he has offered, I read it as him saying "we were poor, it's my fault, I'll go if you want". Ergo he'll be here for a good while longer.
