Ngog has struggled to make an impression since joining Wanderers from Liverpool in the summer, getting on the scoresheet only once so far for his new club.
The Trotters, who go into their clash at Everton bottom of the Barclays Premier League and having scored just five times times in their last eight games, could certainly do with the Frenchman finding some form in front of goal.
And having come up against Ngog day in, day out at Euxton, Knight is convinced it is something that will happen before long.
"I see the strikers every day in training," Knight told the club's official website. "They will get us goals because they are quality players. David has come in and has all the attributes to be a top-class striker for us.
"He's quick, strong and has great technique. Hopefully once he gets one then the goals will start flowing for him because he has looked sharp on the training ground."
