The group stage is going to go on very comfortably for Real Madrid. We must have all understood it from their winning against Napoli away recently. That was technically the toughest match of the group. But even Napoli couldn't stop them in Naples. I can already be confident that Real Madrid will finish as group leader.
The important point is what they will do against the biggest title contenders. Especially against Manchester City and Bayern Munich I mean. If they manage to show a strong team performance with the help of their main scorer Bellingham too then I wouldn't be surprised to see Real Madrid adding another CL title to their collection.

I think it is a given that Real Madrid is going to move to the next round and they are doing it on first place, however their recent performances do open the debate about whether or not they can win the whole thing, as there are teams that are showing a performance that is superior to what we are seeing Real Madrid deliver, still due to their history and economic power we cannot disregard that Real Madrid could do something to turn things around and improve significantly over the next months.
