They entered the 3rd match, if Bayern Munich could beat Galatasaray and Manchester United won against Copenhagen, then it would open up a bigger opportunity for Manchester United, because if the scenario I said happened then the gap between Galatasaray and Manchester United narrowed to 1 point. In the second leg the situation can change greatly and we do not know what will happen, and maybe Manchester United can be even better. Bayern Munich is the club that has definitely qualified, for the runner up we still have to see Mancehsetr UNited first.
I think, the more appropriate scenario is about the success of Manchester United beating Copenhagen. But unfortunately, if for example in the second leg later Bayer Munich and Galatasaray can hold Manchester United to a draw. Then still, that Manchester United will only finish in third place, and will continue in the Europa League . Anyway I am sure, it looks like Manchester United has a chance to win only against Copenhagen because after all, beating Bayern Munich is very unlikely . Also about Galatasaray, it looks like Galatasaray also still has the ability to hold Manchester United to a draw because of course, Galatasaray will also maintain its position to finish as runner up.
Yes their match with Galatasaray in the second leg will be key, whether they can qualify or not. Let's just say Bayern Munich will beat Galatasaray and Manchester United. And Copenhagen can be beaten by Manchester United in 2 legs at once, and Galatasaray can also beat Copenhagen in the second leg after their first leg draw. That makes a scenario where the match between Manchester United will be decisive. Galatasaray only need a draw for them to qualify from the group stage, while for Manchester United they must win if they want to qualify from the group stage.
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.
Most likely so, if there are no surprises then Real Madrid and Napoli have a big chance of qualifying from group C because in terms of quality Real Madrid and Napoli are much better than Braga and Union Berlin.
There have been 2 matches played and Real Madrid achieved perfect results while Napoli lost to Real Madrid (that's a natural thing) while Union Berlin is in the bottom position now after experiencing 2 defeats, this is a very easy group to predict in my opinion.
Provided everything goes well, it will not be difficult for Real Madrid to qualify even by winning the group they are currently in, group C.
In terms of strength, in my opinion only Napoli are close to Real Madrid, even that is only close and cannot equalize their position with Real Madrid. As for the other 2 clubs I think they are still far away if I compare their strengths.
Now Real Madrid are also in a very good state too, they are playing well in La Liga and so in the Champions League. So it's quite easy for them to travel in this group phase.
