I feel like Copenhag has the advantage of the pitch, that is the biggest thing that people are not talking about. These players are used to playing there, they have played there for a long time, some of them played there all their life, but Galatasaray players will be foreign to the weather and the pitch.
The pitch can't be grass, like not the grass we know, not the dirt and grass that we use everywhere, it's still fine by regulations, but it's a bit more rough, not really "fake" but more rough, in a weather like they have over at Copenhagen they had to change it, and Galatasaray players will not be ready for that, they are not used to it, they have mild weather where they live, so between the super cold weather that you may feel freezing, and also the pitch that is different, you are going to end up with a lot of trouble for the Galatasaray team, and if they failed to win at home, imagine how much difference that cold weather away game will be.
In the first meeting at Galatasaray headquarters, Copenhagen was able to provide resistance to the home team. In fact, Copenhagen was ahead with a 0-2 advantage. Unfortunately, in the 73rd minute one of Copenhagen's players was given a red card. In the end, Galatasaray was able to equalize the score to a 2-2 draw.
referring to the first point you said, this is quite reasonable and worthy of consideration, especially considering their initial match meeting. Apart from the points you are talking about, in their last 5 matches Copenhagen is experiencing a decline in performance. 3 defeats, 1 draw, in the Domestic League and 1 more match, a draw against Bayern Munich. However, because this match is being played at Copenhagen's home ground, they will appear all out in front of their own supporters. Moreover, they have great motivation as they finished second in the Group A phase.
As for Galatasaray, they performed quite well in their Domestic League. In fact, as professional players, they must be ready to fight in any weather and terrain. Moreover, Okan Buruk's squad also wants to win to accompany Bayern Munich in the next round. Referring to betting options, the odds provided by bookies do not have a significant difference. So, these two teams both have a chance. However, because Copenhagen acts as the home team, they should be able to maximize this match and it will be an advantage for them. Just wait, because in the next few days this match will be held.
