Burnley boss Sean Dyche was left frustrated by their 2-0 defeat to Southampton.
Dyche felt his side were denied a clear penalty by referee Roger East as Jose Fonte challenged George Boyd moments after Kelvin Davis' first spectacular save.
"It is impossible how we didn't get a penalty, I have seen it back," he said.
"It was certainly very surprising we didn't get a penalty. I don't mention it too often but that is the third one in a matter of weeks that we haven't had."
But it was the lack of a clinical edge in front of goal that Dyche believes cost his side a chance at getting out of the relegation zone and adding to the eight points they have collected away from Turf Moor so far this season.
"I thought we had four key chances, certainly three, and we didn't take them," he added.
"They were good saves from the keeper but I played with Kelvin a long time ago and they are saves a keeper of his calibre was expected to make.
"I was disappointed in the finishing because at half-time you're scratching your head at how we are 1-0 down."
