Leeds United were beaten 2-1 by Brighton & Hove Albion at Elland Road.
The Whites have had a real problem in front of goal this season, with none of their front-men looking particularly clinical over the early part of the campaign.
Leeds' problems with scoring were highlighted in their 2-1 defeat to Brighton & Hove Albion, after Chris Wood missed a golden chance from close range.
The New Zealand international missed a header from six-yards out which could have put Leeds in front, but Rosler was reluctant to criticise the summer signing afterwards, as the German boss says that he has been trying to get his strikers into those positions on a more regular basis.
"The difference between a team where we are and a team where Brighton are, is that they use every chance they have on goal, and we need a little bit more," he said.
"I tell my strikers that we have to get into those [dangerous] areas more often and they will score more."
Leeds actually had plenty of possession against Brighton on Saturday afternoon, but they were beaten in the last minute by the league leaders.
Chris Hughton's side's greater cutting edge eventually paid dividends, and their result leaves Leeds without a win in any of their last 11 matches at Elland Road.
That record will have to change if they want to start moving up the Championship table, and the club's forward players are under pressure to start firing soon.
