I agree there is no really convincing or dominant team so far in this CL edition but I've never given group stage performances too much importance when talking about who'll win CL. Yes, obvious 5 or 6 teams are always labelled favourites to win even before the start of the season (and they usually stay favourites even if they have problems during group stage as long as they are qualified) but you can dominate your group - even a very good one - and then go out in Round of 16 if you draw a good opponent. Or even against worse team on paper if you are not in your best form or have injuries/suspensions when both matches are played in February/March.
