Bayern Munich are the favorite of everyone in this group. It's too early to say that Galatasaray will advance to the next round. But if Manchester United lose points against Copenhagen, I will start to think that Galatasaray will qualify for the next round.
I also think that no club apart from Munich and Galatasaray have a big chance of qualifying from Group A. Copenhagen has only collected one point. Actually I favor United as runners up but if you look at these 2 defeats then United's chances of qualifying are almost impossible. Even though it's still early but I see everyone also agrees that Munich and Galatasaray will qualify even though there are still 4 matches left for each club.
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.
