Sancho has been struggling to recapture his best form at new club Aston Villa, since making a loan move from Manchester United.
The winger has not started a Premier League game for Villa since making the switch, and Dortmund are now being viewed as a potential destination to help him get his career back on track.
His previous loan spell at Chelsea last season failed to reignite his career, and there is increasing belief within English football that Sancho may soon need to step away from the Premier League entirely in order to rebuild.
Man United still hold his contract but are not expected to trigger an extension option on his current deal, meaning he is set to become a free agent next summer.
Dortmund have shown in the past that they can be the ideal environment for Sancho to enjoy his football and thrive.
He previously played for the Bundesliga side until 2021, when he made a big-money move to Manchester United, before returning on loan for a successful spell in 2024.
His wage demands as a free agent could determine whether Dortmund can afford to bring him back once more, but there is optimism that he would be willing to make the move work.
Sources have confirmed that high-ranking officials at BVB continue to hold Sancho in high regard and believe his style of play would fit perfectly with the team once again.
