The report claims that Sancho has grown tired of Manchester City and is looking to complete a move away from the club soon.
Sancho does not see himself breaking into the City first-team, given the lack of faith put into some of the squad’s best young talents.
The report goes as far to say that Sancho has already been to visit Dortmund’s training ground ahead of a potential move to the club.
City want to keep Sancho but the young Englishman has rejected a professional contract from Pep Guardiola’s side.
He has been refusing to train with Manchester City in an attempt to force a move away, with Dortmund seemingly his preferred destination at this stage.
