They were exactly that thought last season but I feel they lost that "factor X" and they are playing much more predictable this season. I don't even trust them against weaker teams. They just aren't a same side without Jović and Rebić. They needed a bit of that Balkan mentality to always do your best against top teams.
Has somebody watched first Leipzig game after the corona break? Were they bad in it or just unlucky? Thinking of betting against them today, have a feeling this one could end up a draw.
they were not bad, Freiburg scored in the first half, and that changed the game for them, but they had an initiative, good chances, on the other hand should lose, since Freiburg scored in last minute, and VAR decided to deny a goal, here is an article on that one

although, do think that Leipzig is out of form at the moment, and they are not title contender any more
