Burton Albion

Man United 4 Burton 1

The attacking duo, deployed together for the first time in the starting XI this season, each found the net at Old Trafford as United booked their spot in the fourth round.

Jose Mourinho picked a strong side, featuring the mouth-watering front three of Martial, Rashford and Jesse Lingard.

And their quality was in evidence immediately, the hosts moving ahead in the fourth minute through Rashford's cool finish.

That opened the floodgates as United entered the break 3-0 ahead, Rashford adding a second before Lingard got in on the act.
