I didn't expect Galatasaray to beat Manchester United at Old Trafford, Manchester United had a bit of a bad run of form recently but this was a Champions League game and it's never easy to beat Manchester United in front of 75,000 people at Old Trafford but Galatasaray did the hard thing with a great game and surprised everyone. If Manchester United get 6 points from the two games against Copenhang and 3 points against Galatasaray in Istanbul they will have 9 points and can get out of this group, but they will have to go through hell in front of Galatasaray's passionate fans in Istanbul.
There are still 4 more matches that can change their position in the standings table. However, it was quite difficult for them because the mentality of Manchester United players in the Champions League was really not good because the two defeats they experienced would make them even more depressed in every match. Galatasaray will take advantage of the situation that occurred with Manchester United because if they succeed in maintaining consistency in the upcoming matches, there is a big chance that Galatasaray will be more favorites to qualify for the round of 16.
Manchester United were defeated by Galatasaray in the previous match. And indeed, if you look at the statistics, Manchester United's performance in that match was really not good, especially since their defensive line was quite weak, making it easier for their opponents to beat them. In Group A of the Champions League, only Bayern Munich are the most consistent because they managed to secure full points in the two matches they have played.
