I'm not sure Galatasaray will be able to complicate Bayern Munich's plans in that match, of course because I think Bayern Munich have good goal statistics so far. Galatasaray have been quite strong so far and maybe that can help them prevent Kane et al from scoring lots of goals, but I believe Bayern Munich will be really hard to stop this season.
Harry Kane has scored 1 goal and 1 assist in the Champions League in 2 appearances, while Kane has also scored 8 goals and 4 assists in 7 appearances in the Bundesliga. I believe Kane et al will be difficult to stop and Tuchel's plan for that match is to win, but if Galatasaray manages to win points in that match then I believe they will have a good chance of qualifying for the last 16.
The first leg match will be played at Galatasaray headquarters, like it or not, Okan Buruk will prepare his team to provide resistance when they host Bayern Munich. At least if they fail to overthrow Bayern, Galatasaray will look for a draw point to maintain its ranking in the Group A phase and hope that Manchester United's match will also be a draw against Copenhagen. Or, Okan as Galatasaray coach still has to prepare his team to play offensively.
The point is that they also want to get through from the Group A phase, especially since Galatasaray is now in 2nd place. The opportunity to qualify for the next phase is quite wide open for Galatasaray, especially if the team coached by Okan Buruk is able to match the play of the squad coached by Thomas Thucel.
As I said above, at least they are aiming to get a point, even just 1 point. but it is not an easy matter for them even though they are playing at home. because after all, Galatasaray and Bayern Munich have a fairly unequal level, we can compare them based on the quality of the players, as well as the team's performance. and as we all agree, Bayern has a big chance to win matchday 3 of the Champions League group phase. and I suspect, this match will present an interesting match.
