Paulo Di Canio bemoaned the lack of a ruthless striker as Swindon's three-game unbeaten run ended with a 2-0 defeat to Burton.
Goals from Billy Kee and Jacques Maghoma secured the points for Albion, much to the dismay of fiery Italian Di Canio.
He said: "Once again, we had possession of the ball and played most of the first 40 minutes around our opponents' box but we can't score a goal.
"This is my frustration and the club knows this. We don't have a centre forward and I'm not happy about this. We need a warrior in the box.
"We had 10 or 12 potential chances from crosses, free kicks or corners but we couldn't take one of them. Then, the goalkeeper makes an incredible mistake and it's difficult for us.
"Even if I expected much more from my players, they should fight for a comeback and that was a disappointment.
"I am very sad, very disappointed because we should have had a step up but we have taken a step back."
