England winger Jadon Sancho has completed his £73m move to Manchester United from Borussia Dortmund.
Sancho is the second most expensive English player of all time behind his new United team-mate Harry Maguire.
United agreed the fee for the 21-year-old on 1 July.
"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 one day," Sancho said.
"The chance to join Manchester United is a dream come true and I just cannot wait to perform in the Premier League.
