"I think I am lacking a bit of composure in front of goal because the goals haven't been flowing in for me this season," said the Liverpool skipper.
"I've done everything right except the finish but I was pleased against Holland that I was getting into those forward positions.
"I've got every confidence the goals will come. This season I've been getting in the positions to score and it has not quite happened for me.
"Last season mis-hits and deflections were going in for me. The goals will come and that is all that is missing at the present time."
