The Sun reports that the 21-year-old England forward is all but signed, but the deal is yet to be officially finalised, so the player has yet to be unveiled as the club’s first transfer of the summer.
The player is due to cost £73 million as the Premier League side finally met Dortmund’s valuation after failing to do so last season - though in that summer transfer window the Bundesliga team wanted north of £100 million to let the player go.
Manager Ole Gunnar Solskjaer explained the situation which was the cause of the delay in the player being announced.
Speaking after their 2-1 win over Derby as they prepare for the new Premier League season, the Norwegian said there were just: “Small little details left.
“Hopefully it will be announced soon.
“Let’s get the paperwork done and get it all over the line.
“Then I can say what I truly feel about the player.”
While Sancho appears almost certain to join the club this summer, giving the United boss the new right winger he has wanted for a year, there are other expected arrivals, with differing degrees of certainty.
At the back there is talk of Real Madrid’s Raphael Varane having agreed to join United, with a £50 million asking price thee sticking point, given Real want to maximise his value with just a year left on his contract, and United hunting a bargain for the same reason. Elsewhere in the Spanish capital, a £18 million asking price for 30-year-old right-sided defender Kieran Trippier is also wanted, to provide competition for Aaron Wan-Bissaka, who has failed to sufficiently kick on with his attacking ability since his move from Crystal Palace a couple of years ago.
