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.
Bayern Munich is the strongest team in the group and also one of the favorites to win this season, but that doesn't mean they don't have weaknesses and counter-attacks from opponents will always be an obstacle for a team that is concentrating on attacking, any team will always have difficulty dealing with that, but for me in the group phase Bayern Munich is still quite safe, they can concede or even get a draw in the next match, but It is quite certain that they will pass the group phase and the next focus is how to reduce mistakes that make their defense look weak, when they entered the knockout rounds and remained a productive team by always scoring goals in every match.
