AC Milan were only in the UEFA Cup last year --> Pot 1
Inter have won several Scudetto in a row --> Pot 2
Bayern, German runners-up --> Pot 1
Wolfsburg, German champions --> Pot 4
AZ Alkmaar and Rangers --> Pot 2
At Madrid, Fiorentina, Bordeaux, Stuttgart and Marseille --> Pot 3
I know the seedings are based on European performance, but some of this is baffling.....
