We should be listening to offers for all of our players, particularly those who don't have relegation clauses in their contracts. This isn't a case of accepting our fate that we will be a Championship club, if Pickford does leave in this window I'd want the money received to be reinvested into players who we believe can turn our fortunes around. However, a prudent club (which we are not) will be thinking of contingencies now in case the worst were to happen.
If the only way we can do business this window is by selling players then absolutely everybody is fair game in my opinion.
