Portsmouth boss Michael Appleton felt his side offered enough to pick up three points, but Bristol City's Derek McInnes was happy with a 0-0 draw.
Pompey created a number of chances at Fratton Park on Saturday, but failed to take any as they were held by their fellow Championship strugglers.
Appleton was disappointed to see his team draw a blank, with a share of the spoils leaving Portsmouth bottom of the second tier table and eight points adrift of safety.
He said: "People talk about sides creating enough chances to win two games, but we created enough chances to win six.
"It's the situation where we are at the minute - getting in fantastic positions and having fantastic chances but we're just snatching at them a bit.
"There's a lack of confidence in front of goal with some of the players - a little bit psychological with one or two of them.
"But I can't ask any more of them. There was some fantastic opportunities and football in the second half, and maybe it's going to take it to come off someone's back-side or knee to kick-start it again."
Bristol City boss McInnes saw things slightly differently, with a point enough to keep his side four points clear of the drop zone.
He said: "I am happy with a point and the draw in the end and I was delighted with some of our defending. It was excellent.
"I thought we battled very hard and threw our bodies in front of everything. We worked extremely hard and it's another point towards avoiding relegation."
