The draw took place in the last hour.
Manchester United and Wolves could be on track to meet each other in a Europa League semi final.
United will bring a 5-0 advantage into their last 16 second leg with LASK - and would face either Copenhagen or Istanbul Basaksehir in the quarter finals.
Should Wolves get the better of Olympiacos to reach the last 8, they'll have a difficult quarter final against either Roma or Sevilla.
On the other side of the draw Wolfsburg or Shakhtar will go up against Frankfurt or Basel in the quarters.
The winner of that will be paired with one of Inter Milan, Getafe, Rangers or Leverkusen in the semis.
