It looks like the group leader in Group C has already been decided.

Because getting a win in Naples was going to determine the leader in the group technically for Real Madrid. Because I expect Real Madrid to win all the remaining Braga and Union Berlin games ahead above all else. After that I guess that Real Madrid wouldn't surprise me by losing the lead to Napoli in Santiago Bernabeu.

Real Madrid seem more credible to me to play bigger this season. I'm saying this even though they had Benzema last season.
Because there is a much bigger progress in their performance compared to that season. Bellingham has changed this team a lot too but I like the team effort more at the same time.
Group C is a relatively easy group for Real Madrid. Of their three competitors, perhaps only Napoli is predicted to provide a little difficulty, but because Napoli can currently be said to be experiencing a decline, it makes it easier for Real Madrid to become the leader of this group standings until the end. When they face Braga or Union Berlin, even though it is an away match for Real Madrid, they will still be able to face it well.
Jude Bellingham has made quite a change in the Real Madrid team, and it is quite surprising how he has been able to adapt since his first match with the big Spanish club.
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.
