The Red Devils have been handed a relatively friendly draw in Group A, avoiding the likes of Bayern Munich and Real Madrid in Pot One.
United 10/1 to win Champions League
Portuguese champions Benfica did reach the last 16 in 2016-17, but Basel and CSKA Moscow both finished bottom of their groups without winning a single game.
CSKA finished second in the Russian Premier League to return to Europe’s top competition, while Basel are the Swiss champions.
United, of course, triumphed in the Europa League last season in order to seal a return to the Champions League despite finishing sixth in the English top flight.
Matches will kick off on September 12, with the group concluding on December 5.
