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.
Group F is certainly the most interesting in this Champions League group stage match. Almost all of them actually have the potential to qualify. Milan is showing good performance in the Ligue 1 they are not performing well in the Champions League competition. Who knows, maybe they will be able to improve their performance in the Champions League, it is really uncertain which teams are actually going to qualify. The only team that I am confident about qualifying is actually PSG and trust me I really hate saying this.
