Impressed: Sergio Romero
One of Manchester United's best players on the night, Sergio Romero put in a fine display between the sticks. He wasn't tested to a great extent in the first half, but made a string of great saves in the second period to keep his side in the lead.
First up, he produced a fine save to deny Seydouba Soumah after the Partizan winger had evaded a couple of challenges to unleash a strike at goal.
He then kept out Takuma Asano's goal-bound header as well, to add to the Serbian side's frustrations. Romero was also commanding from set-piece situations over the course of the game.
Poor: Nemanja Miletic
Nemanja Miletic was one of the few Partizan Belgrade players to really have an off-night. The Serb brought down Brandon Williams in the box in the first half, gifting Manchester United a penalty which Anthony Martial gleefully converted.
Things turned from bad to worse for Miletic in the second half as he was booked for dissent after being denied a penalty of his own.
He looked suspect defensively, especially after the arrival of Marcus Rashford late in the game.
