The attack power on Dortmund's front line is very weak
Borussia Dortmund is a very good team. This is a team that have transfer structure, they don't just spend on player that don't worth. Though right now the club is going through a rehebilation process . They brought in Sébastien Haller, who scored couples of goals for the team .
I agree with you, that Borussia Dortmund is a big club and contributes the most players to the German national team, so it is not surprising that Borussia Dortmund will always have expensive players for the long term such as the unknown player who has just been brought in Sébastien Haller, the starch will be being a player like Erling Haaland whose name was adopted by Borussia Dortmund, of course it is very interesting with this player, whether Sébastien Haller will be like the next Erling Haaland..
You will never be able to produce the same player as haaland again. Haaland was haaland and there would never be a copy cat for haaland. Haaler can become a potential player but it will still be far from haaland. I don't feel skeptical toward him but seeing the gap between his performance compared with haaland made me sure if haller was not as good as haaland. Dortmund was still struggling in the bundesliga. Its performance is still being very far from good. Dortmund needs to develop its player even further.
This club has been losing so many talents which were joining in the various club even its rival bayern munchen as well.
Dortmund is always being inconsistent club in any season. The club was not lucky enough last season caused by it was almost winning the league but munchen was lucky enough to pass dortmund with only 1 point gap
Haaland is far better than haller.
