The Potters' 0-0 draw with West Bromwich Albion this afternoon means that they have only scored one goal in their last four matches, and their tally of 27 goals in 30 league matches is among the lowest in the league.
Pulis concedes that such a meagre total of goals is disappointing, but the 55-year-old is determined not to dwell on his side's missed chances.
Asked if he was worried about the lack of goals, Pulis said: "Yes, very much so. The final third at times has been the problem, but it is something we have to get on with.
"We got into some fantastic positions today and that final ball, or the movement, didn't lead to the goal we need. That was disappointing. I thought it was a very competitive game without many chances in it.
"At the end Kenwyne has probably had the best chance of the game and unfortunately for us, he has ended up hitting it straight at Foster. When things are going for you, that would have nestled in the corner. But it has got us off 33 points, which has been a millstone around our neck - and fingers crossed, now in our last eight games we can push on."
The draw leaves Stoke 10th in the Premier League table.
