N'Gog, who arrived at the Reebok Stadium from Anfield at the beginning of the season, is expected to face his old club for the first time this afternoon.
However, he insists that he is no more motivated to score this week than he has been all season.
"I'm playing against my old club, but as a professional you have to have the feelings that it is nothing different and that it is like any game on a Saturday," he said.
"I'm a striker and I want to score goals. It would be special if I do at the weekend, but winning and climbing out of the bottom three in the league table is much more important."
N'Gog has found the back of the net twice in ten starts for the Trotters this season.
