Galatasaray put in a strong performance in this game, so they are not a weak opponent; they are also a stubborn team with a lot of confidence; it's only that they struggled to score against Bayern; they have the same number of ball possessions throughout the game; they simply have trouble adding on goals in the second half. Before the game started, I made the prediction that Bayern would win, and had it not been for the penalty, they wouldn't have even managed to the score one goal. Bayern is a very dangerous club, and we all know that even in this group stage, I believe that no club will pass them with points. Galatasaray miss many chances they had on their first half, and if they had scored at that time, none of this would have happened in the second half. All they need to be doing is to defense their game but they loses the chances.
At first I thought the same as you Munich could win easily but after seeing how Galatasaray played in the first half then my doubts came because Galatasaray really dominated in the first half and the penalty was not a coincidence they get it through great effort, but unfortunately in the second half Galatasaray's game was no better than the first half and Bayern Munich took the opportunity when they counter-attacked until finally managed to score 2 more goals. overall I wouldn't say Galatasaray played badly they have played well but luck is not on their side, now we are waiting for the results of the match between Manchester United vs Copenhagen we know Manchester will be Galatasaray competitor for 2nd place.
