Sancho has been a revelation for BVB since making the switch from Manchester City, earning rave reviews for his performances, but all has not gone smoothly in this campaign after falling out with the powers that be.
The 19-year-old was dropped and hit with a hefty fine after returning late from international duty with England and was then told to do extra training, which did not go down well with the player.
Sancho is also said to be unhappy with the way sporting director Michael Zorc criticised him in public, rather than keeping it in-house.
To make matters worse, Sancho was then hauled off after just 36 minutes at the weekend as Dortmund were hammered 4-0 by arch rivals Bayern Munich in the Der Klassiker showdown.
Added together, Sancho is said to be frustrated with life at Dortmund and is now ready to push for a return to England after initially snubbing Manchester United during the summer.
United and Liverpool are still in the hunt to do a deal and Sancho will be hoping a move can be pushed through at the end of the season.
It seems as though Dortmund are also open to the idea of selling when the campaign is done, as long as someone comes in and matches their £100million valuation.
Liverpool and United will both be willing to stump up the cash and the final decision could come down to Sancho.
