With his path to the first team still blocked, the Dutch forward has spent time with Werder Bremen and Club Brugge this season.
Although Chong waits on a big break at his parent club, the 21-year-old knows regular game time will aid his development.
Chong has told Sport/Voetbalmagazine: “Staying here for another year could give me stability, but that’s for later.
“As far as I know, there is no option [to extend the loan] in the agreement. We will have to discuss that with Manchester United later.
“I like Belgium. It is a bit like the Netherlands. Something that is in my head: that by staying here maybe a little more stability can come, but it is now difficult to fully focus on that.”
After failing to spark in Germany, Chong joined Club Brugge in January. Explaining his moves in 2020-21, Chong added: “We thought choosing Brugge was a good next step. I already knew the club from a year ago, from the Europa League, and we follow Belgian football a bit. I knew quite a bit about the team.
“Personally, there are still ups and downs here. The team helps me settle down enormously, but it is pushing until the end of the season. I have to get used to the rhythm - playing five, six games in a row... I never did that before.
“I now have to add the end product to my game. More goals, more assists. That will come once I get to know the players a bit better.”
