Ngog is available for Tuesday's meeting with Fulham and, while manager Laudrup may not throw him into immediate action, the Dane believes the forward brings something different to his squad.
"If we are talking position-wise we have been low in numbers recently and we are still in three competitions with the possibility of more injuries going on," he said.
"The other thing is to try and find abilities that you don't have. He's a different kind of forward, he has got that pace one-against-one that could be useful in games.
"What is very important when you look in the January window is that you look to find someone from this style of football.
"You can go outside and bring in foreigners with no experience of English football, but everyone needs time to adapt and we only have three-and-a-half months left in the league.
"So this is a player who has experience of this league from Liverpool and Bolton."
