If you look at the composition of group A, it is clear that Bayern Munchen can win the group. because Man United, Galatasaray and Copenhagen are not a big problem for them. However, if in the quarter-finals Munchen meets Madrid, Man City or Inter Milan, of course their progress to the final will be very difficult. We know that after the transfer market movements, almost all clubs have made changes, the results in the domestic league cannot yet be fully used as a benchmark for moving forward in the UCL, I think.
The composition of the teams in Group A of the Champions League is a composition that is very easy to predict because not all teams have nearly the same strength so almost everyone can guess which team will progress to the next round. It looks like Group A will not be a fierce group in the fight for the group champion and runner-up positions, because only Bayern Munich and Manchester United have more potential to get first and second place in the group.
I think Madrid has a better chance of progressing to the final this season, for Man City I have a little doubt after the departure of several key players when they won the UCL last season.
It is still too early to confirm this now, because in general there are many teams that have made changes so that it is not only Real Madrid that has the opportunity to advance to the Champions League final this season. Manchester City actually still has a chance to advance to the final if Manchester City can be consistent enough from the round of 16 onwards.
