England winger Jadon Sancho says joining Manchester United is “a dream come true” after he completed his £73m move from Borussia Dortmund.
Sancho 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.
United boss Ole Gunnar Solskjaer said Sancho “epitomises the type of player” he wants at Old Trafford.
“He is a forward player in the best traditions of Manchester United,” Solskjaer told the club website.
“He will form an integral part of my squad for years to come and we look forward to seeing him blossom. His goals and assists records speak for themselves and he will also bring tremendous pace, flair and creativity to the team.”
