Jelavic continues to struggle in front of goal, with the Croatian having not scored since January 7 and only once in his last 17 games.
"It is noticeable and everybody talks about it so we tend to be as honest and straightforward as we can," admitted Moyes.
"We don't try and hide away from anything; we tell supporters what we think as often as we can.
"At the moment we need Jela to try and find a way to score us some goals. Forwards always want to finish and score goals and that's changed with him.
"Any forward that has played the game and gone through a barren spell will have their own ideas with what they try to do and address the problem.
"We would like him to score and if he can do that then it would help the team."
