Blackwell said: "I don't know what's going on at the moment. If new people come in they might not want me here anyway.
"I am sure of one thing. I will not be hanging around if we're struggling to get wages in and pay the players.
"That's not a way to run a football club and I won't stay if that happens.
"The players haven't got the credit they deserve and, as a manager, I feel myself and the club have let them down.
"The shame about it is I think we could've stayed up. But the way we're run at the moment, it's no wonder why we are where we are.
"It's a missed opportunity because we were good enough to stay up, but we didn't have the players because of the transfer embargo."
