Chong started for Bremen in a 4-1 defeat against Hertha Berlin on the first day of the season but has had to settle for a place on the bench in the subsequent three matches.
The youngster was reintroduced to the starting XI for Bremen's 4-1 over FC St. Pauli in a friendly on Wednesday and repaid manager Florian Kohfeldt with a well taken brace.
He said afterwards: “It's always nice to score, especially as an attacker, but I've already said plenty of times that I can't score without my teammates.
“For the second goal, Maxi's pass left me completely free – they all make it really easy for me.
“Obviously I would prefer to start matches, but I will still give it my all when coming off the bench. I'm a really patient guy and I will try to keep improving and helping the team."
