Liverpool boss Kenny Dalglish blasted his players after their 0-0 draw with Swansea City.
Their frustration was not helped by a couple of brilliant saves from Michel Vorm late on to deny Luis Suarez and Glen Johnson but the major talking point was Andy Carroll's miss from six yards in only the seventh minute.
"If we had scored early on it might have changed the way the game went but we never scored so it is hypothetical," said the Scot.
"No-one has ever in the history of football deliberately missed a chance.
"That is 10 times we have hit the post or the bar this season.
"Maybe if the chance goes in it may have changed the complexion of the game but as well as paying credit to Swansea we have to look at ourselves."
Even taking into account Carroll's miss, Dalglish felt his side underperformed as they were held to a third successive home draw.
"I think the performance was disappointing," added the Reds boss.
"Swansea played the way we would have expected they would play but we didn't play the way we expected to play. Anything that we were good at we certainly didn't do too much of today.
"We are usually good at passing and moving and there was not a great deal of that and when we got it back we gave it away quickly.
"They had one chance in the second half when the boy (Mark Gower) put it over and Pepe made a save in the first half but we have to understand that level of performance isn't acceptable."
