Bayern Munich played a very comfortable football, it was like a training match. We saw what an important player Joshua Kimmich is for the team, the team played amazing. Unfortunately Hertha Berlin was very weak and could not play the ball.
This team will be one of the biggest favorites for the champions league, if there is no injury to the players, I think the championship will come

Hertha Berlin is no match for Bayern. In fact, no other team other than Dortmund can match Bayern's potential and their growth. They had a goal fest with Berlin as 4 of the players scored - Tolissol Muller, Sane, and Gnabry. Bayern are already a hot favorite to win this year's CL along with teams like City, PSG, and RMA. What concerns me the most is that they sometimes lose a match against smaller teams without any valid reason.
It is just Dortmund that is preventing Bayern from converting German league to farmers league just like ligue 1. Those guys are too good.
In terms of champions league, they are big favourites to contend. And will really need to watch them dash some clubs upto 8goals even at round 8 or 4.
For them losing to small clubs without reasons...lolx, the reason is; this is football, a game of skill and luck.
