Celtic secured top spot in Europa League Group E with last night's 3-1 win over Rennes, coupled with Lazio's 1-0 win over Cluj.
That means Neil Lennon 's side will be seeded for the last 32 of the competition, meaning they cannot play any of the other group winners.
Eight teams will come down from the Champions League but Celtic cannot face the four with the best records as they'll be seeded too.
Country protection will be in place for the draw so the Hoops cannot face Rangers - though as things stand Steven Gerrard's side are top of their group and will also be seeded.
Finally, Celtic cannot face Cluj or Lazio as two teams from the same group can't play each other in the last 32.
There is still one round of fixtures to be played in the Champions League and Europa League group stages so all we know for sure is that they won't play Espanyol or Sevilla.

APOEL
