So far Real Madrid haven't lost and managed to beat Napoli. Probably it really won't be difficult for them to play Braga and Berlin. But still we should not underestimate the opponents, although this group is one of the easiest. Probably Real and Napoli will be able to go further. The important thing is that no one gets injured.
Most likely so, if there are no surprises then Real Madrid and Napoli have a big chance of qualifying from group C because in terms of quality Real Madrid and Napoli are much better than Braga and Union Berlin.
There have been 2 matches played and Real Madrid achieved perfect results while Napoli lost to Real Madrid (that's a natural thing) while Union Berlin is in the bottom position now after experiencing 2 defeats, this is a very easy group to predict in my opinion.
