Rashford’s emergence as one of the top young talents in football also saw him included in England’s Euro 2016 squad.
Speaking about his talent, Mourinho praised the youngster for his composure against Manchester City.
“Every individual reacts to demands of the occasion in different ways.”
His incredible rise has only gotten better after he bagged a hat-trick on his England Under-21 debut earlier in the week, after finding the winner against Hull City.

Mourinho was pleased with his efforts and picked up on the fact that he always looks at home on the senior side where he belongs, no matter what he’s doing he always looks ice-cool.
