Obviously, United cannot meet Villarreal or Atalanta or any of the English clubs in the next phase. Group G will pose possible opponents, however, with everything wide open in this section.
Wolfsburg are currently at the bottom but will qualify if they can beat the front runners Lille in their last game at home. French master Lille only need one point from this game to advance but are out if they lose. RB Salzburg are in second place and need to avoid a home defeat in order to Seville in their game. Sevilla have to win to overtake the Austrians.
The draw for the round of 16 on December 13th will take place in Nyon, Switzerland, at 11:00 GMT. It will be shown live on BT Sport in the UK. The group runner-up will be at home in the first leg, the away goals rule no longer counts.
Teams in bold are the ones we could face in the round of 16.
