The Belgian originally joined the Potters in 2013 and has gradually developed through the club's academy system, with his progress seeing him enter boss Mark Hughes' thoughts in recent months.
After making his debut away at Arsenal in December, he was given another chance to shine on Saturday, coming on for the final 18 minutes of the 2-0 FA Cup third round defeat to Wolves.
The 19-year-old has recently been tipped for a loan move in a bid to help his development, but with Jonathan Walters struggling with a knee injury and Mame Diouf and Wilfried Bony both away on African Cup of Nations duty, he could well be given more of a chance in the coming weeks.
Ngoy believes he is fully prepared to step into the breach and says he is ready to put in the required work in order to convince Hughes he is ready.
"I think I can play in the first team," Ngoy said. "The coaches are giving me a lot of advice, every day, and I am doing what they want me to do. I will keep working hard to be a first team player here.
"I would prefer to stay and fight for a place in the team than go out on loan now. I don't think about a loan move for the moment."
He added: "For now my objective is to keep working hard and to maybe one day to start in the side."
