Several teams that have consistently won in the last 3 Champions League matches are Bayern Munich, Real Madrid, Manchester City and Barcelona. I think these four teams will only need 2 more wins to maintain their chances of safely qualifying for the next round and I think it will be quite easy for them. For Bayern Munich and Real Madrid, perhaps they are in a quite difficult group because Manchester United and Napoli are predicted to disrupt their chances, but it seems that is no longer a problem. On the other hand, Manchester City and Barcelona are in a group filled mostly with weak teams and I think it will be easier for both of them to secure points in the next match without any problems.
Even some of them only need 1 more win to ensure themselves will qualify for the last 16 of the Champions League this season. They swept all their matches with a win and even the victories they got had no significant obstacles.
I know it's too early to say this, but I'm pretty sure the 4 teams you mentioned will be in the round of 16. I also know anything can happen in football, but looking at the opponents they will face, at least 2 wins is realistic for them.
Meanwhile, the competition in group F is still very tight with a very tight point difference from the 4 teams that are joined there.
