The victory means the Reds will be seeded for the draw for the knockout stages of the tournament, which takes place at 12:00 GMT in Nyon, Switzerland.
United are one of 32 teams in the hat for the next round, along with fellow Premier League clubs Arsenal and Wolverhampton Wanderers, as well as Scottish sides Celtic and Rangers.
With the group stages of the competition all wrapped up, the Reds now know which teams we can be paired with in the knockout stage.
United will be drawn to play one of the unseeded teams and we could face one of 14 different sides, including the likes of Getafe, Sporting Lisbon, Eintracht Frankfurt and Roma, who all finished second in their respective Europa League groups.
