Sancho returned to England for his first game at club-level since leaving last week as Dortmund were comfortably beaten 3-0 by Tottenham at Wembley.
However, according to media reports, Ole Gunnar Solskjaer is lining up a mega-money move to bring the promising young talent back permanently.
The report claims the Red Devils have been told they must pay £70m to secure his signature though. It would be a controversial move given Sancho spent over two years at City’s academy.
Pep Guardiola did not want to lose Sancho but could not give him regular first-team football in a squad that already has the attacking talent of Raheem Sterling, Leroy Sane, Riyad Mahrez and Bernardo Silva in his position.
Sancho, who has scored eight goals and provided 13 assists from 29 appearances this season, is said to be enjoying life in Germany.
It is claimed a caveat to the deal would be that City shall be owed 15 per-cent of any transfer fee, a clause that was negotiated into their £8m deal with Dortmund that saw Sancho leave.
City would also have a chance to match any offer that comes in for Sancho, giving them first refusal on their former star.
