As with the Champions League draw earlier, the draw takes place at UEFA headquarters in Nyon, Switzerland, and will follow a similar format.
Teams will be drawn from the two pots, with unseeded teams drawn first, then their seeded opponents drawn thereafter.
As before, teams cannot face sides from the same country, and they can't be drawn to face teams they've already faced in the group stages.
It has also been decided by the UEFA Executive Committee that teams from Russia and Ukraine also cannot be drawn together.
