David Wetherall was speaking after seeing his City side lose at home to Orient in a game they just couldn't afford to lose.
"We have to start working towards getting three points at Chesterfield - that's our only option now. We don't give up.
"Everybody is extremely down and that's an understatement. We're still scratching our heads as to how we lost that game.
"There is still an opportunity for us but we need to win two games. People who were there on Saturday will see we are capable of doing that but now we are relying on other people to have a real slip for us to get above them."
Things are looking bleak for City who find themselves 4 points from safety with just two games to go.
