Bayern Munich and PSG have always been the ones topping their leagues for many seasons and that is why they’re seen as less competitive leagues compare to other top leagues in Europe. It was only in last season we saw Bayern Munich falling from that position but just this season they were able to reclaim their title back.
Last two seasons you mean, because we don’t have an on going season as we speak. Bayer Leverkusen despite doing greatly 2 seasons ago didn’t show the same resilience last season.
You are right on the fact that, the dominance of these two teams in their respective league makes it look a lot less competitive and that’s usually based on the fact that, the quality of players in these teams are unmatched in the entire league and mid tier teams in the Bundesliga are always in a hurry to sell their prized players off in the transfer markets.
Makes them look like they are not in the business of winning trophies.
