The young England international continues to be heavily linked with a move away from BVB despite the fact the transfer window is now closed.
Sancho has said on more than one occasion that he is happy where is and will not push for a move, while Dortmund officials have also said he is not for sale at any price.
Even so, that did not stop questions about his future after he helped Dortmund to a 0-0 draw against Barcelona on Tuesday night, a game they should have won.
Manchester United are known to be in the hunt, but Sancho reiterated he's happy where he is.
"I can't tell the future. I just take it game by game. I just wanna give 100 per cent for Borussia Dortmund," Sancho told reporters.
"I really want to do well with Dortmund. Obviously, I want to win titles and give everything."
Sancho sprung to prominence last season with 12 goals and 14 assists as Dortmund finished second in the Bundesliga, and he has already chipped in with two goals in this campaign.
He is also an England international, so life is good for the talented 19-year-old.
"It's crazy. Everything has come so fast," Sancho added. "But I have a great team. They keep me humbled. I just take it game by game and give 100%."
