Manchester United boss Louis van Gaal says he has to find a solution against the lack of goals by his team.
The Red Devils have only scored 20 goals so far this season compared to the 32 of leaders Leicester City and the 27 of second-placed Arsenal.
And the Dutchman reckons that it is a problem that has to be rectified.
"I think that we played a very good match, it's only we have to score," van Gaal told reporters.
"Of course it's frustrating but I look first at my own team – that's the most important thing. We have to win in Wolfsburg – we need to score also in Wolfsburg to survive in the Champions League.
"You must score out of the kind of chances we created. You need to score, otherwise you cannot win, and it is very frustrating, also for the players because they want to score. We have to finish better than we did today.
"You can train every day on shooting at the goal and you have to know that we are doing that.
"We put players in the position to score but you need composure and luck to score. The most important thing is that we are creating and we are dominant. Today, we were dominant and attacking, we were creating chances – only we forgot to score.
"[If I understand the fans' frustration?] Yes and no, because they can see that we fought until the end. There was a fantastic team spirit and we were dominant.
"We created many chances and you can only do that when you are attacking; we attacked much more than our opponents, who were defending in their square of 40 metres. That's always difficult but we created a lot of chances. Yes, you have to score from those chances and we didn't do that. That is our problem in the latest matches."
