The Nigeria international is enjoying a run in the Newcastle first team but, despite some excellent displays, a goal has not come his way.
His last league goal came against Queens Park Rangers last year, and he is desperate to find the back of the net.
"I am extremely frustrated. I am playing well but not scoring goals," he told the Evening Chronicle after missing a good chance in Saturday's 1-1 draw with Southampton.
"I should have buried that header in the second half, it was bread and butter for me. It is frustrating and something I need to work on.
"As a striker you gain confidence from scoring goals. I have to add them to my game in the rest of the season. I am working hard in training to make sure I get into positions and hopefully they will come soon.
"It is a long drought now. It is something I am trying not to think about.
"When you do that it affects you. But for all that the team comes first and as long as we win that is all that matters. On a personal level I want to break that duck as soon as I can.
"When the team is winning you want to get in among the goals. Hopefully, I will put it right in the next few games."
