Roy Keane was left frustrated again after watching his side miss a hatful of chances in the draw with Bristol City.
Dean Gerken was outstanding in goal for the Robins, producing top class saves from Gareth McAuley, Daryl Murphy and Jon Walters to keep the score goalless.
"Credit where credit is due, their 'keeper was brilliant. He was in the first game but we had enough chances to have won the match," said Roy.
"They were great chances as well and our performance in the second-half was excellent.
"I couldn't wait to get the team in at half-time because we couldn't have been any worse in the first-half. We waited for something to happen. You've got to make it happen.
"We were completely different in the second-half. The players were outstanding but we just couldn't put the ball in the net.
"It's a clean sheet, so that's another positive but it's another draw and that's incredibly frustrating."
