He'd still command a big transfer fee and you could bring Henderson back as 1st choice, he seems to be made of the right stuff. Gives you funds for a CB.
It depends on ambitions. If we're not simply about making up the numbers in the top 4 or CL then we need someone to come in and be better than DG.
Fck knows what's going on in his head. He used to save us 20 points a season plus. He's still more than capable but he's having brainfarts you expect a top keeper to be making in his late 30's not 29.
