Of course they are weak. They lost every tournament last year and in most of them they were eliminated not by Bayern at all, but by other much weaker teams. The Champions League, then the Europa League, the German Cup - they failed everywhere. Now that Haaland is gone, it's hard to imagine that they've gotten stronger, right? And this means that in the upcoming season their achievements will hardly be better.
I would say losing all competitions you are in doesn't equal to weak. I mean Fürth lost and didn't get the title, and so did Dortmund, does that make them equals? Or Wolfsburg who had a good start but we all know what happened. Basically what we are talking about something that is "decent enough" and not bad or weak. I believe Dortmund is "weaker" which is something else.
I think top 5 would be decent enough and we would be doing better right now. I know people are expecting them to be so much worse but I believe that top 5 is more than enough, why would they need something else? So all in all I think it is reasonable to expect them to have a situation where it would make sense, and I would guess that it would take a while before they could make some more transfers and maybe get another player who would be awesome.
