I was not surprised that Hoffenheim defeated Bayer Leverkusen because Hoffenheim is a tough team in the German Bundesliga, and coupled with the departure of Xabi Alonso and Bayer Leverkusen's best players this summer, I knew Bayer Leverkusen wouldn't defeat Hoffenheim because this season Bayer Leverkusen is quite different from last season Bayer Leverkusen. I don't see Bayer Leverkusen to compete in the German Bundesliga this season, but since the German Bundesliga is ongoing, we will see if Bayer Leverkusen would perform well.
I agree with you. Leverkusen is not as strong as they were in previous seasons and we may not see their dominance this season. The main reason for this is the change of coach and the appointment of Ten Hag, who is already known as a bad manager. Another reason is the departure of the best players.
They were not aggressive against Hoffenheim, although they were able to keep the ball, but Hoffenheim dominated them and won the match. Although Leverkusen scored in the first 6 minutes, they did not score any goals in the rest of the game, but conceded 2 goals and lost the match 2-1.
