Millwall manager Kenny Jackett was disappointed with his side's lack of cutting edge after the 1-0 defeat to Sheffield United.
Andy Reid, on loan from Premier League side Sunderland, netted his first goal for the Blades which proved to be the only goal of the game.
That win moved United up to 19th in the table and out of the relegation zone whereas the Lions slipped to 17th in the Championship.
And Millwall boss Jackett feels that if his side had converted their host of chances and been a bit more spontaneous, then they may have been the ones taking the three points.
"The bottom line is results and it's important to recognise that. A lot of our play is right and in the first half we created chances but as the game went on you could see the confidence drain out of us," he said.
"Sheffield United weren't really a threat but they didn't need to be.
"We had half a shout for a penalty and it did look a penalty to me. It looked like we needed a break like that.
"While we're disappointed with the result, two thirds of our play is pretty sound. We need to go past people in the final third and be a bit more spontaneous.
"We couldn't break them down enough and we needed a bit more quality and pace to go past people and take them out.
"We've scored one goal in two games and that's a tough ask - if you don't score it can creep in and inhibit other parts of your play."
Meanwhile, Sheffield United manager Gary Speed was delighted with the three points in what he deemed was a match they could not afford to lose.
"That was a very important win for us and hopefully we can build on that now," he said.
"The important thing is not go into the game with Palace and waste it. We need to win that so hopefully we can take some confidence from this win.
"I hope it's not a false dawn because we've had a couple of those before. This is a difficult place to come and they put their bodies on the line. All things considered it was a fantastic result.
"I'll have to speak to Steve Bruce and [Andy] Reid as well. I knew he is a quality player when I brought him here and he chipped in with a goal but he's shown he's a good player since he's arrived. But it was a good all round performance by everyone.
"Second half we lacked a bit of confidence and I felt we could have pressed on a bit more and looked for a second goal but we held on and overall I'm really pleased.
"I thought Millwall had the majority of the game second half and that was the one disappointing thing.
"I think we looked dangerous on the break but we didn't get on the break enough - we sat back a bit and were cautious, which is understandable."
