Jadon Sancho says its “a dream come true” joining Manchester United after completing his £73m move from Borussia Dortmund.
The winger is the second most expensive English player of all time behind his new United team-mate Harry Maguire.
He joins United on a five-year deal.
“I’ll always be grateful to Dortmund for giving me the opportunity to play first-team football, although I always knew that I would return to England,” 21-year-old Sancho said.
“The chance to join Manchester United is a dream come true and I just cannot wait to perform in the Premier League.
“This is a young and exciting squad and I know, together, we can develop into something special to bring the success that the fans deserve.”
United agreed the fee for Sancho on 1 July and his five-year contract with the club has a further 12 month option.
The completion of the deal brings to an end United’s protracted pursuit of former Manchester City player Sancho. They had expected to sign him last summer but could not agree a fee.
Sancho scored 50 goals and registered 57 assists in 137 appearances for Dortmund.
