My guess would be van Veen, possibly Turnbull.
I think you might be right as Austin says to get them to join in January they had to put clauses in the contracts that they could go if we went down. Tbh if either of van veen or turnbull don't want to be here then send them on there way. At least Austin has said they are going to be adding another keeper and he has one in mind. I guess Goff will be loaned out again and Coddington will either be loaned or sent on his way
