Facing Galatasaray, Bayern Munich must pay special attention to their defense if they don't want to concede. Galatasaray will probably play quite carefully in this match and playing at home gives Galatasaray the opportunity to get victory or the match ends in a draw.
The counterattack that Bayern must anticipate when facing Galatasaray because seeing from their game against Manchester United, the long passes of the Galatasaray players for counterattacks are quite troublesome and this must be anticipated by Bayern who always attack by locking up the defence and their players always come out of their posts to help attacks such as Davies and Mazroui who are always active in helping Bayern's attacks this could be a gap for Galatasaray.
But I'm pretty sure with the current difference in strength then this will not be a problem for Bayern and they will still win 3 points in this match.
Facing Galatasaray cannot be taken lightly. Because Galatasaray really has a very fast counterattack strategy. But Galatasaray's defense is actually not that good either. Sometimes their defenders move too far forward and are too late when returning to the back area. And I'm sure Bayern will be able to beat Galatasaray. Because the quality of Bayern's attack and defense is at a higher level. Galatasaray in the match against Man Utd they were very difficult. Even though we know Man Utd is not at its best this season. Meanwhile, Bayern is currently still in good form. But Bayern should not underestimate Galatasaray. because maybe Galatasaray will give a surprise.
When it comes to quality of players between Bayern Munich and Galatasaray, it's very obvious that Bayern Munich are better the Turkish club.
That being said, Bayern Munich must play in their full strength if they really want to win double header games they have against Galatasaray. At Manchester United last week, Galatasaray showed that they're not a team to mess around with as they defeated the English Premier League club in their own turf. Bayern Munich is very beatable and would be beaten by Galatasaray if they underrate their opponents.
Now I would like to say that Bayern Munich should not lose the match against Galatasaray. But Bayern Munich should also not take the match lightly as you said. We have seen Bayern Munich not give enough importance to their opponent just because they thought the match was going to be easy. And they ended up dropping points or losing because of that. I will say that Bayern Munich is in good form right now. So they should be able to win this match.
At the same time, Galatasaray is also in good form. They showed a good performance against Manchester United. They are also showing good performance in their own league competition. Bayern Munich should be careful.
