I have seen a lot of comments from different people venting their frustration at Borussia Dortmund and Bayern Leverkusen, which is normal, but we all only blame the teams without appreciating the fact that their opponents might have gotten better this new season. Before two seasons ago, Bayern Leverkusen was just an average team and was not regular at top four, but soon they got better and started winning and even kept the record of being undefeated for a season. We might be seeing something like that this season in some of these other clubs. For Borussia Dortmund I don't know what their problem is and the reason for their stagnation for several years.
Sometime peoples react too early because they never want their favourite clubs have bad performance but sometime need to understand these was first games of season with new players and coach always need time to adjust conditions. Borussia Dortmund have good start as they were in lead 1–3 defender Mane red cards bring them down St Pauli took advantage of this opportunity and bring themselves on level through 2 goals.
Bayer Leverkusen took early lead and have good control of game against last seasons struggling Hoffenheim, but they were not able to convert their chances which give them upset lost now surely they could be well-prepared otherwise they're surely going out of touch because in few weeks Champions League is also going to start which could be increase their problems.
