Dortmund just doesn't consistently get full points in every match they play, I don't think they are completely bad this season in the Bundesliga. We can see how their journey has been in seven weeks, it is proven that even though it is less than satisfactory, Dortmund have not been defeated so far. In this case, Dortmund is the same as two other teams, namely Laverkusen and Bayern Munchen.
Maybe when compared to last season there is a slight difference in Dortmund performance, it's natural because they are released a star player like Jude Bellingham, it's still good that they haven't been defeated. I think when the transfer window opens, Dortmund will bring Sancho home from Man United but this is still speculation.
Comparison with Dortmund performance last season, success lead top position before loss the opportunity for winning domestic league tittle last match depend with inconsistency performance from rival team Bayern Munich. Have difference condition this season with Dortmund performance although not have many points difference on current standings position, Dortmund left two points from top standings team Bayern Leverkusen but they have draw 2 of 7 matches in domestic league and bad performance in Champion League.
I don't see with Dortmund have good chance in this season for domestic league tittle race with Leverkusen and Bayern Munich because their performance still inconsistency although until 7 matches in Bundesliga still unbeaten yet.
Dortmund isn't really doing bad to start giving a verdict on them at this times, let's not forget that Dortmund in the recent past Haas successfully breed good and brilliant young players, in the likes of Jude and haland but they end up always selling them off most often so I think it's very possible before the end of the season there could be the rise of another star.
This could mean they may turn out very good than expected of them and most likely out perform others but their biggest challenge will still remains Leverkusen and Bayern Munich. I think it yet too early to say if Dortmund wouldn't make it to getting a trophy this season although I'm most pessimistic about their performance in the UCL but at the domestic league the have a good chance of finish top if not the winners only if they will not sell out yet another young talent.
