United finally officially announced on Friday that Sancho's £73m transfer from Borussia Dortmund was officially completed. He will wear the number 25 shirt for the Red Devils in the new Premier League season that starts in the middle of next month.

Manchester United negotiated a transfer fee with Dort on July 1, and on July 13, Sancho passed the medical examination and signed a contract, but Manchester United officially announced his joining after 10 days, because his agent had some minor problems.
Sancho, 21, said in his transfer statement: "I will always be grateful to Borussia Dortmund for giving me the opportunity to play first-team football, although I always knew that one day I would return to England and the chance to join Manchester United was a dream come true, I just can't wait to perform in the Premier League. It's a young and exciting team and I know that together we can develop into a special team that brings the success it deserves to the fans. I look forward to working with the head coach and his coaching team to further develop my game."
In Manchester United, Sancho also has a lot of familiar team-mates for England. He made his debut against Croatia in October 2018 and developed a deep friendship with Rashford. "The first time I met Marcus was when he was first selected for England," Sancho said, "he didn't go to the first training camp, I remember the second time, and then, when we played against the Czech Republic, he and Jesse (Jesse Lingard) joined." He and Jesse were obviously together, I started talking to them, we started staying together, and since then we've gotten closer and closer."
"The European Championship was the first time I met Luke (Shaw) because he hadn't been selected in a long time, but Luke was a great guy and one of the people I could talk to in the locker room. I hope my England team-mates will help, we talked about it at St George's Park and I'm sure they'll help me settle in, whatever I need, I'll go to them and they'll definitely help me."
Manchester United manager Ole Gunnar Solskjaer said: "Jayden (Sancho) has condensed the characteristics of the player I want to bring in, he is the best striker for Manchester United, he will be an integral part of the team in the next few years and we look forward to his growth. His record of goals and assists speaks for it, and he will also improve the team's pace, talent and creativity. Old Trafford will provide him with a platform to unleash his untapped talent and perform on stage at the highest level. As a young player, Jaden has achieved a lot and shown the courage to go abroad to prove himself. We all look forward to welcoming Jaden in the training camp."
According to the British "Daily Star", Sancho's weekly salary is not the rumored 350,000 pounds, but only half of this amount - 175,000 pounds.
Wearing the no. 25 shirt, he also unexpectedly became the 10th no. 25 player in team history. After fixing the shirt number in the Premier League, Gary Walsh, Kevin Pirkington, Jordi Cruyff, Fowjong, David Jones, Danny Simpson and others crossed the number. The most famous owner of The 25 is Antonio Valencia, a veteran captain who has been with the team for 10 years, and after joining Wigan Athletic, he wore this back number to replace Cristiano Ronaldo's winger position, and was once the best in the team.
For their outstanding performances, Valencia won the No. 7 at one point, and that year, youngster Nick Powell received the No. 25 shirt. But The Great Valen did not perform well in the No. 7 and quickly switched back to his old numbers and wore them until the end of Ole Gunnar Solskjaer's first season in charge, when he left the team. The most recent to wear the number 25 is Nigerian striker Ighalo.
Sancho said, "Yes, it's a real honor. As a child, Manchester United were one of the biggest clubs, they won a lot of titles and there were many iconic players. I'm happy to wear this shirt now, I'm hungry to win, determined to win, scoring goals, assisting and occasionally showing a little bit of skill."
Manchester United team-mate Bruno Fernandez welcomed Sancho on arrival: "I look forward to playing with you, Old Trafford, are you ready?"
Manchester United captains Maguire and Marcus Rashford also commented on the arrival of new signings, in which his friend Master La said: "Welcome, brother."
Sancho also said he would learn from Fernandez and other teammates. "They have a lot of experience in the competition, including the finals." "So learning from them is a wonderful thing, and working with them will be a different feeling," he said.
Currently, Sancho is still on holiday, having traveled to Turkey and the Caicos Islands in Latin America, surfing the sea in hopes of escaping the shadow of a penalty in the European Championship final.
Although United have officially announced his signing, he will not return until August 2, and his debut may be the last warm-up game at home against Everton on August 7.
On 14 August, The first round of Manchester United's Premier League was also played at Old Trafford. Sancho said: "I'm excited about the new season, especially the first game at home, in front of my own fans, which is always an inspiration of confidence, so it's good."
Sancho boasted of winning for Manchester United in the new season: "I can't wait to start and obviously want to bring the trophy back to where they belong. I can't wait, see you later."
United's first-round opponent was arch-rival Leeds United, with Sancho jokingly saying he had warned England team-mate Kevin Phillips: "I told him to be careful, so he already knew."
