In case this "Done Deal" isn't done after all, I've had a bit of a trawl round to find available keepers and come up with:
Ross Turnbull (Ex Donny, Chelsea etc)
Jon McLaughlin (Ex Bratfud, Burton)
David Martin (Ex Dongs)
Alex Cisak (Would you have him back? No, me neither)
Chris Weale (Ex Yeovil)
Scott Flinders (Ex Gillingham, Hartlepool)
And, I'm really sorry, but a certain Mr Brill is also available.
Out of that lot, and it may not be a definitive list as there could well be more that we've heard of, I'd be very happy with McLaughlin or Martin.
