However, Sancho has not officially told Dortmund that he wants to leave this summer. There is still a chance that the winger could stay in Germany for at least another six months beyond that.
Sancho is under contract at Signal Iduna Park until 2022, so there is a possibility that he could leave the Bundesliga club the following January instead.
Either way, the Yellow and Blacks will want at least £84m for a player who has made a huge impression in the two-and-a-half years since he moved to Germany.
Sancho has scored 30 goals and provided 41 assists in 87 matches for Dortmund, as well as scoring twice in 11 caps for England.
