The 18-year-old has also featured regularly in the Champions League, making 28 appearances in all competitions this season.
"I'm happy that I've opened doors," Sancho told ESPN http://www.espn.in/football/uefa-champions-league/775/blog/post/3772910/sancho-exclusive-im-happy-that-ive-opened-doors-for-young-english-players-with-dortmund-move in an interview ahead of Dortmund's trip to Tottenham Hotspur for Wednesday's Champions League last-16 tie.
"It's a good thing to give other players the opportunities somewhere else and not just at home. It's a good feeling, a nice feeling.
"They do ask me what it's like (making the step up from the reserves to the senior team), and I tell them truthfully: It's not easy. It's difficult."
Sancho is expected to start for Dortmund against Spurs with captain Marco Reus ruled out with a thigh injury.
