Bayern Munich and Galatasaray are gonna progress at the expense of Man United and Copenhagen.
It could be wise to take Manchester United out of the picture, in terms of teams that won't qualify in that group, but in my opinion, I can't specifically say that Galatasaray and Bayern Munich will only scale through and take Copenhagen for granted. So for me, both Galatasaray and Copenhagen have an equal chance of qualifying in that group alongside Bayern, regardless of which team is ahead of the other in their group table.
Looking at the Group A standings after completing the first two matches, only Bayern Munchen can be said to have a bigger chance than the other three clubs, namely Galatasaray, Copenhagen and Man United. I think Munchen can qualify from the group phase even though they are not the leaders of the standings, and the runner-up slot is still likely to be contested by others, but for now Galatasaray looks more promising than Copenhagen and United. Maybe all predictions regarding who will qualify for the next stage will be clear when matchday three is finished, and we can see a clear picture on the standings board.
Munchen will visit Galatasaray headquarters, on paper Thomas Tuchel squad can get full points. Likewise Man United will host Copenhagen at Old Trafford, I would also say United can secure full points. I certainly haven't forgotten about the various surprises that could happen, but looking at the depth of the Munchen and United squads they should be able to do it.
