From pot one (final pots subject to seeded teams coming through qualifying rounds, Arsenal and Porto specifically) we will face one of Real Madrid, Barcelona, Atletico Madrid, Porto, Benfica, Bayern Munich. This is likely to be the game with the biggest allocation and also the most popular. Anyone with one credit from 2 years ago will be sorted, and there will be some left over after that.
From pot 2 and pot 4 it is a little less predictable. We could get Dortmund from pot 2 which would be a good allocation, and Roma from pot 4 which would also be a decent allocation although a few people might not fancy that. However we could end up with Basel/Leverkusen from pot 2 and Anderlecht from pot 4 which would be small allocations and fairly easy to get to, making tickets hard to come by.
In short it really depends who we get. I would say at least one game will drop to no credits, but it may be season ticmets before members in that instance. 28th August is the big day when we find out.
