Young has recently made his mark back in the Man United starting line-up, putting in a number of impressive performances at left-back.
Mourinho provided a surprise on Saturday morning when he named Young as his right-winger at Anfield.
Speaking ahead of the game, Mourinho said: “When he plays right or left back he plays because we have needs. He plays in his normal position today, nothing new.”
While it’s true that the more attacking wide position is more natural for Young, it shows how accustomed United and football fans have come to Young playing in defence.
The Englishman is one of United’s most reliable players, and has been since arriving from Aston Villa under Sir Alex Ferguson.
Young wasn’t that effective on the right-wing at Anfield, but United rarely attacked. Henrikh Mkhitaryan, too, was relatively anonymous.
The 32-year-old is a useful option to have for big games given the defensive solidity he provides from an attacking positon, and that’s likely why Young used him over Juan Mata.
The Spaniard was fully fit having not been called up for his country’s 2018 FIFA World Cup qualifiers in the last two weeks.
