Ferguson was adamant the visitors should have left the Valley with at least a point, claiming "the better team lost."
"It is just unfortunate maybe the way things are going at the moment," he said.
"We didn't get a break, like the one that spun off Lee Tomlin and hit the post. We had a very, very, very good performance.
"I think you've got to take the positives out of any game and I've seen enough tonight to tell me we'll be okay.
"I think if any neutral had been at the game tonight and had looked at the league table before the game, that performance would not suggest we deserve to be at the bottom.
"I thought there was some really good performances and, as I said, the better team on the night lost the game but that is football."
