Roma coach Jose Mourinho has questioned Manchester United's deal for Borussia Dortmund winger Jadon Sancho.

Sancho, who completed his United medical on Tuesday, joins a squad already including Mason Greenwood, Anthony Martial, Marcus Rashford and Edinson Cavani.

Former United manager Mourinho told The Sun: "Jadon Sancho has gone to United, Marcus Rashford is also there and Mason Greenwood is a good example of a player who wasn't in this squad but can be in Qatar, when he will be much more mature and has a good possibility of being selected.

"Three young England players in one club, three with potential to play in the national team.

"Which one will have an amazing season but which one could be hidden, not starting many matches because of the coach's decision? Greenwood has the talent to be there."
