Frustrated Stoke City boss Mark Robins says his struggling side "look like they don't know how to score a goal", adding it was "an absolute joke" that not enough desire to get into their opponents' box was shown in Wednesday's defeat at Charlton.
A persistently long injury list has hampered the Potters' play-off challenge for much of the Championship season and the 1-0 loss at The Valley was their third defeat in the last five games and extended their run without a win to six matches.
Stoke, who were second after 11 games, remain in 14th place, four points off the top six, but have played one more game than three of the four teams in the play-off spots and two more than third-placed Ipswich Town.
Although they had 63% possession against the Addicks, they mustered only two shots on target and had an expected goals ratio of 0.5.
"It was hugely disappointing," Robins told BBC Radio Stoke.
"We didn't take our chances. We didn't take our chances to shoot. And we didn't get bodies in the box enough for the rest of the game which is an absolute joke.
"Once we got on top we played in a way that gave us the opportunity to go forwards and create good opportunities.
"From back to front we were OK, but it looks like we don't know how to score a goal at the moment."
Not getting bodies in the box 'unforgivable'
Stoke's blank in front of goal was the 13th time this season - and third game in a row - they have failed to score.
And Robins said when they get the chance to attack, they need to start doing it much more effectively.
"I'm saying the same things all the time. We need better outcomes. We need crosses in the box, we need runs in the box, people challenging because it makes a mockery of all the good play that we've got.
"I'm not even talking about being ruthless - we just need to take responsibility for a shot and not keep turning it down and get bodies in the box to be able to tap the ball in at the far post. It's unforgivable.
"It's bone idle. Get yourself in a position to go and score. That's your job. Go and take opportunities to shoot.
"Sometimes it's difficult but shift the ball and shoot. These are things that have been there most of the season."
Stoke were without nine players through injury and illness before Wednesday's match, which became 10 when Bosun Lawal pulled a hamstring late in the first half.
Robins pointed to the difficulties that he has in maintaining any kind of consistency in team selection.
"That is a joke. I'm struggling to pick people because they're starting to pick up injuries. I've got to navigate that," he said.
"It's so difficult to keep everybody fit and to be able to have the luxury of being able to keep a settled team, a settled back four but it's an impossibility at the moment.
"People think you can just keep magicking results. At some point it catches up with you.
"We've got a good squad but to get results on a consistent basis you've got to have those players available. You cannot legislate for the injuries we've had."
