The midfielder is already regarded as one of the most talented players in the German top flight and is among the most coveted young players in world football.
In addition to offering an update on his future, Bellingham reflected on his development at Dortmund, where he has benefitted massively getting regular first-team football.
"I have my destiny in my hands and I know that if I try hard and trust the people around me, I can move forward," said the teenager. "I came from England as a young talent. There was not much pressure. The first season went well. There were also matches where I sat on the bench and sometimes I did not play at all.
"I think my development this year has meant that I have played a bigger role in every game except two. I am very grateful to Dortmund for the way they have nurtured my talent.
"I think a lot of the credit goes to the coaching staff and the staff who keep the noise around me. In this way I can only focus on winning matches, because that's what I'm here for."
