The Evening Standard claims Sancho has been persuaded to move to Old Trafford because of the chance to play with three United stars.
The 19-year-old has already struck up a friendship with Marcus Rashford on international duty.
It is also claimed he rates Anthony Martial, who has been United’s main striker this season, backed up by 18-year-old Mason Greenwood – the third player Sancho is looking forward to linking up with.
Dortmund have slapped a £120million price tag on Sancho, with the Bundesliga side’s chief executive Hans-Joachim Watzke attempted to play down the chances of his player leaving earlier this month.
“I think he has the feeling that the club does have a good future,” Watzke told BBC Sport.
“In my opinion, I don’t think he wants to leave.
“We have a very confidential relationship between us and him and his agents, we will discuss it.
“It’s not a question of money. For us, it would be the best position if he stays at Borussia Dortmund.
“We have enough money. We want to have titles. I think this team has a lot more potential with Jadon than without Jadon.”
