Manchester United are set to seal an 85million euros ($A134.5m) deal for Jadon Sancho after agreeing a deal with the England international and his German club Borussia Dortmund.
Bundesliga giants Dortmund confirmed the details on Thursday.
The winger, 21, is currently on England duty at the European Championship, where he has only featured as a substitute.
Sancho must first pass a medical at United before the transfer is completed.
"The player Jadon Sancho is about to move from Borussia Dortmund GmbH & Co. KGaA to Manchester United Football Club Limited," a club statement from Dortmund to the stock market read.
"Both clubs and the player reached an agreement on this today.
"If the transfer is realised, Manchester United will pay BVB a fixed transfer fee of EUR 85.0 million."
United started their pursuit of Sancho last year but Dortmund held out.
They have finally agreed to let him leave, sparking speculation the Bundesliga side will now do everything to hang on to their other prized attacker, goalscoring ace Erling Haaland.
Sancho joined Dortmund from Manchester City in 2017 having decided he would struggle to make the first team at City.
He went on to become one of the German top-flight's most feared wingers, using speed and trickery to set up assists as well as weighing in with 38 goals - 16 this past season.
He won the German Cup last season and the club again qualified for the Champions League.
German pundits were astounded that he is not starting for England at the Euros, such has been his impact at Dortmund.
The 1997 European champions, whose new coach Marco Rose was officially unveiled just as the Sancho news was confirmed, have tried to change their infamous image as a selling club but the money on offer from United has proved too tempting.
"We are not excited about the money, instead we are sad that he is leaving," chief executive Hans-Joachim Watzke told a news conference.
"We wanted to keep him."
Although Sancho had expressed a wish to leave, Watzke said he had behaved "in an exemplary manner".
Rose regrets Sancho's departure but is glad there is now clarity as they seek a replacement.
United finished second in the Premier League to City last season and a pacey winger has long been on manager Ole Gunnar Solksjaer's wish list.
Sancho will provide competition for Marcus Rashford on the left and could also play on the right where United have been lacking.
