Sancho's joining Manchester United also has one of the biggest suspense, which number he will wear. It's almost certain that Sancho won't wear the Red Devils 7 in the new season.
At present, on the official website and official website of Manchester United, the first team No. 7 still belongs to Uruguayan veteran Cavani. In his first season, Cavani made 39 appearances and contributed 17 goals and five assists, breaking United's No. 7 spell after Cristiano Ronaldo. It makes sense that Cavani should continue to wear the Red Devils' No. 7 jersey.
Veteran reporter and y Mitten, who covered Manchester United, broke the news that Sancho is likely to wear the number 16 shirt after joining. The numbers currently vacant in the Manchester United first team are 12, 16, 24, 25 and 32. Number 16 is one of the few vacant numbers in Manchester United.
Roy Keane (1993-2005)
Since the Premier League era, United have only three players wearing the no.16, Roy Keane, Michael Carrick and Marcos Rojo. The first two of them are well-known.
Keane is not only one of the greatest captains in The History of Manchester United, but also the Greatest 16th Player in the Premier League.
Carrick (2006-2018)
After Keane's departure, Carrick joined from Tottenham, took over the number 16 shirt and played for the same 12 seasons.
Both Keane and Carrick are members of United's "1+5+10", i.e. have won at least 1 Champions League, 5 Premier League titles and 10 trophies.
Sancho wants to wear the number 7 shirt only after Cavani leaves next summer.
