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.
