How the draw worked
The UEFA administration formed groups for the draw to avoid clubs without an approved stadium being drawn against each other, in accordance with the principles set by the Club Competitions Committee. Sides from the same association could not be drawn against each other.
Champions Path
The balls containing the names of the seeded teams were placed in one bowl and the balls containing the names of the unseeded teams were put into another bowl. One ball was taken from each bowl and placed in a large empty bowl in the middle, where they were shuffled. The first team drawn plays the tie at home. The last two balls containing unseeded teams were drawn one after another to pair them.
Main Path
Groups 1 to 3
All clubs in the three groups were ordered randomly and given a number: 1 to 3 for the seeded teams and 4 to 6 for the unseeded teams. Two bowls were prepared, one containing balls with slips of paper numbered 1 to 3 and the other containing balls with slips of paper numbered 4 to 6. A ball was taken from each bowl, placed in an empty bowl and shuffled. The first ball drawn will play the tie at home. The result of this draw was applied to Groups 1 to 3.
Group 4
All clubs were ordered randomly and given a number: 1 to 4 for the seeded teams and 5 to 8 for the unseeded teams. Two bowls were prepared, one containing balls with slips of paper numbered 1 to 4 and the other containing balls with slips of paper numbered 5 to 8. A ball was taken from each bowl, placed in an empty bowl and shuffled. The first ball drawn will play the tie at home.
