Hall and Hanson are probably surplus and should be given a hearty handshake and a painting of a Spitfire, and encouraged to find a loan club with a view to a summer move, or even freed now.
Any number of the youth teams who are good enough to make a contribution to a Division 4 club should go; Lopes, Spasov, Jones, Goodrham, Sole. Napa would be close enough to fitness to go out now.
When Forde's back I see him as a legitimate contender for RB cover, and I'd rather keep Agyei and Sykes as options - we still need to field a 7-man bench.
I can't see any value in bringing in another GK - I'm pretty sure we could still get an emergency loan for a keeper later in the season after the window closes, if necessary(?)
