The winger's contract with the Premier League big boys is set to expire next summer. Fierce competition for a place in United's starting XI prompted the 21-year-old to join Belgian side Club Brugge on loan in January.
Brugge are said to be interested in acquiring Chong's services on a permanent basis, although the Dutchman is refusing to make any hasty decisions.
Chong told De Kraant van West-Vlaanderen: “I look at it step by step. If I start thinking about where I want to be next year, I wouldn't be focused on Anderlecht next Sunday.
“I can only do my utmost. And enjoy the game. I always try to play football with a smile. My focus is now on the two remaining matches and the play-offs. You will have to prove yourself there anyway.
“(If I could choose) then I would go home and discuss it with my mum and dad. Then I'll listen to the pluses and minuses. Then we'll work it out as a family."
