The new league phase format sees each of the 36 teams play eight games, four at home and four away.

During his two-and-a-half-year spell at United, Mourinho led it to UEFA Europa League glory in 2017, beating Ajax 2-0 in the final.

The Red Devils' remaining seven games include an all-British home clash against Rangers, welcoming the Glasgow giant to Old Trafford for the first time in 14 years, and a trip to another of Mourinho's old clubs, Porto.

Rangers, which has failed to win any of its past 13 games in major European competition against English opposition, will also face Tottenham Hotspur and UEFA Conference League winner Olympiakos.

Spurs, winners of the inaugural tournament in 1972, will also meet Roma and Galatasaray in their other seven fixtures.

Meanwhile, in the UEFA Conference League, Chelsea's draw includes League of Ireland side Shamrock Rovers at home and a trip to Panathinaikos.

The Blues, who narrowly qualified for the competition this week, have never faced any of their six opponents in any competition before.
