The 15-year-old striker is being talked up in his homeland as the next big star in European football, and has attracted interest from a number of major clubs.
Real Madrid, Barcelona and Paris Saint-Germain are all believed to be monitoring the talented teenager's situation, but face a fight to secure Ngoy's signature after his father hinted that a move to the Premier League would be his preferred option.
Jose Mourinho might look to lure Ngoy to Stamford Bridge, and could use the club's growing contingent of Belgian players as a bargaining tool to convince the youngster that his future will be best served in west London.
However, Gunners boss Arsene Wenger has a reputation for nurturing and developing up and coming talent, and that might persuade Ngoy's representatives that Arsenal would be the best place for him to realise his potential.
Tottenham could weigh in with an offer of their own, while Manchester City should not be discounted either, with new manager Manuel Pellegrini also having a history of working with and bringing through young stars during his time at Malaga.
Ngoy is not currently attached to a professional club in Beligum, so teams will have to negotiate with the country's famous Brussels academy as they look to secure his signature.
"Julien is a big talent, one of the biggest I have seen in my academy," confirmed academy director Nkandu Ntondo. "No decision has been made yet."
