Placing these two teams H2H you will see that they are not at all of equal strength even in personalities we have the like of Kane and the rest to deliver Munich but I'm yet to see any person in Galatasaray who can contend those in Munich, although Galatasaray may be on good morale now because they may still be in the ecstasy of the win they just had over Manchester united but then if they manage to make it to the knock out stage it will be a good achievement for team amidst the big contenders they have on their group.
Bayern Munich are better than Galatasaray but we all know that Bayern have weak moments where they are performing badly and Galatasaray could profit from these moments to pick a point for exemple.
Odds are way in favour of Bayern Munich although they are playing an away game. This group depends a lot from Copenhagen games and the direct game between Galatasaray and Manchester United.
