Honestly I am not very optimistic, they simply look better, if I had to say it in numbers I rate them the best team alongside Bayern, then Chelsea, then us and maybe some others. Games like this can always finish anyhow but in the past I had this feeling we can destroy them if it's our day and they were fighting hard, now...now I think is vice versa: they can destroy us (like 4:1) and we have to fight hard to take something.
I even don't think CR is in some special form, I watch their games a lot, it's not that he is doing something else, physically he is in great shape as always it's just that the team creates so much space for him he scores even more.
