I think that a weakened Bayern team will still be enough to at least draw with, if not beat what seems to be a very poor Barcelona team. Both teams have had and still have a lot of injuries which could still play a part and might even form Bayern to pick a stronger team than they might have done otherwise.

I think Benfica will win their game very comfortably so for Barcelona, I only see a campaign in the Europa League. And I expect that to end in disappointment too.
