Chong penned a new contract with United last month.
He told the Official Manchester United Podcast, “When United come, United is one of the biggest club's in the world so it's almost impossible to say no to. So, I think when United came, it was no to everyone else and just discussing 'am I just going to stay in Holland or is it United'. I think the other options weren't even there."
Chong also revealed the spirit within the squad's younger players.
“Yeah, I would say I still have a lot of improvement, a lot of things I want to improve as a player. But like I said, the manager is showing trust in youth players. Not only me, but I feel like if I'm not on the bench and I see Angel [Gomes] or Mason [Greenwood] or Brandon [Williams] whoever it is on the bench or even on the pitch it feels like a proud moment because these are boys I've known for a couple of years now.
"So it's just a proud moment for me to see them on the pitch, even if I'm not involved, to see them is still a proud moment for me."
