Hammers seeded in group 2
In the draw each team 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.
