Would love to see Zenit (Saints-Petersburg), Dynamo (Kiev) and, especially, Astana (Kazahstan) drewn with City. First of all, it's aviable to go there (for the Blues from Eatern Europe at least). Secondly, these places are the interesting ones to visit (Even if Dynamo Kiev plays in Lvov - both Kiev and Lvov are wonderful palces). In the end, all three teams are arguably the easiest ones in their pots (Zenit are probably stronger than PSV and Benfica).
However, I would not be surprised if we get Bayern/Barca, CSKA and Borussia/Zagreb
