Delaney’s error on the stroke of half-time was enough to give Nottingham Forest a 1-0 win and leave Keane’s Tractor Boys just three points above the relegation zone.
To add to Keane’s frustration, Ipswich finished the game with 10 men as Grant Leadbitter was shown a straight red card for a high challenge on Paul Anderson.
“We lost to an own goal but I wouldn’t say we were unlucky. There are no pity parties,” he said.
“A lot went on before the goal and we had possession of the ball. We should have done better. We would have been disappointed had it been 0-0 at half-time — let alone be 1-0 down.
“Forest are a big, strong team and they defended well. I didn’t think we played badly, though, and there wasn’t a lot in it.
“We showed endeavour, determination and commitment. Their goalkeeper made a great save from Troy Brown.
“In the second-half we were chasing the game, though, and it would have been the other way round if we’d scored first.
“The first goal was massively important. We’re nearly a good team but nearly never made it.
“Scoring goals is the hardest part of football and it’s been a problem for us since I’ve been here, in terms of our final ball and being clever in and around the box.
“One or two of the players make the wrong decision. We’ve taken one point from six in the last few days but I’m convinced we deserved more. Then again I’ve been saying the same thing for a year and a half.”
For his part, Forest boss Billy Davies is pleased with his side’s haul of points over the busy Christmas period following yesterday’s win.
Forest are only two points outside the top six after just one loss in the last nine matches and while Davies is aware that his side can not afford to rest on their laurels as they push for a play-off spot in 2011, he was happy to praise his players for their efforts against the Tractor Boys.
“It was a fair result,” said Davies. “We had some great chances and we’ve got to be delighted with 10 points out of 12 over Christmas. January will be crucial but we’ll keep ticking along.’’
In the first half, David McGoldrick, who also played a key part in the winning goal, accidentally hit the bar from a drop ball, when he was trying to play the ball back to Ipswich goalkeeper Marton Fulop.
Davies said of the incident: “I apologised to Roy Keane before he punched me!
“It was an accident and we’d have been gutted had it gone in.
“The goal would have stood but I’d have asked the referee to disallow it or we’d have done something at the other end to even things up.”
The game marked Aaron Ramsey’s final appearance for Forest as he will return to parent club Arsenal because his loan expired yesterday.
Davies added: “Aaron Ramsey has been a credit to himself and I’d like to thank him and Arsene Wenger. We wish him well for the rest of the season.”
