Nathan Jones was pleased with the endeavour of his Charlton side despite drawing 0-0 against Mansfield at the Valley.
The Addicks are seven points adrift of the play-offs places after their sixth draw of the season and they remain winless at home in the league since early October.
Miles Leaburn went closest to scoring for the south London hosts as his 60th-minute header grazed off the right post.
The young centre-forward, 21, is yet to score in the league this season and also fired wide when played through by Tyreece Campbell.
Karoy Anderson had a big opportunity in the sixth minute but took too many touches as he broke into the box, allowing Mansfield keeper Christy Pym to come out and foil him.
Jones said: “I’m just disappointed we didn’t show enough quality from a lot of situations to have won it.
“The positive is that once again we’ve shown we are a very good defensive unit and limited them to very little.
“That is the frustration – that we couldn’t capitalise on another clean sheet.
“The players are putting their bodies on the line. They are trying. We’ve tried to be really expansive today. We’ve had more possession than Mansfield and they are a possession-based team.
“We’ve created three clearcut chances and should’ve had a penalty – the one on Miles in the second half, where he gets pulled back, that would be a penalty if we had VAR.
“There was an edginess which the players are handling and I understand it because fans want more – they want to see more chances and us score goals. We’re working religiously on it.
“We’re a young side and at the end I couldn’t get any more attacking players on the pitch to try and win that game. It shows they are giving me everything.
“We’re not happy with that stat (one win in nine matches) and we know we need to be better, wins-wise.
“I’m not sitting back being defensive. We are aggressive. Us and Birmingham are the best pressers in the division – we are going after teams and being front footed.”
Mansfield had lost their last five league matches and had two close-range chances but Lucas Akins blazed over from about 10 yards out in the 27th minute with Elliott Hewitt similarly wasteful in the 63rd minute.
Stags manager Nigel Clough said: “It was brilliant to stop the rot when you have lost five consecutive league games – undeservedly so.
“At least we got something we deserved today and the very least we deserved was a point.
“It was lovely to get the clean sheet as well as the point.
“We needed a result today – a win or a draw – as we didn’t want to have six defeats with the Christmas period ahead.
“We battled and scrapped and defended well to a man today.”
