The 32-year-old, who joined the Reds from Southampton over the summer, has made nine appearances so far this season and went close to opening his account against West Brom before the international break.
But the England international is confident that the goals will come.
“I’ve missed a few chances, which I look back on and I know I should have scored,” Lambert told Liverpool’s website.
“But I try not to beat myself up too much. I might have done that in the past a little bit too much.
“I’m trying to relax a little bit more and just believe in my ability, because I know I’m good enough and I’m working hard enough.
“It’s not too far away, the first goal. Whenever that comes and whatever way it comes, it’s going to push my confidence even higher.”
