The UEFA Europa League first qualifying round draw will be made today at 12pm with the second qualifying round draw at 1.30pm both streamed live on UEFA.com.
Teams are ranked according to their coefficient and further split into seeding groups prior to the draw with West Ham top seed for the first qualifying round from 102 teams.
Groupings for the second qualifying round will be made after the first qualifying round draw. The balls representing the winners of each first qualifying round tie will take the coefficient of the seeded club in each tie.
In both draws, each side in each seeding group is allocated a number. Balls containing the seeded numbers are placed in one bowl, with balls for the unseeded numbers in the same group positioned in another.
A ball is taken from each bowl and put into a large empty bowl in the middle, where they are shuffled. The clubs whose numbers correspond to the first ball drawn play their first game at home, against the teams whose numbers match the next ball drawn.
