Bundesliga is similar to Ligue 1, that only one club is the strongest and the favorite to win the league. However, we have more stronger clubs in Bundesliga than Ligue 1, which was the reason why Leverkusen came from nowhere and won the title under Xabi Alonso. I don't expect to see any surprises again from Bundesliga, because Kompany has put the club back to her standard.
Yes, of course it's different because in Ligue 1 there is only one of the richest and strongest clubs while in this Bundesliga there are several other rich clubs that are able to build squad to be stronger and able to compete to get the title.
Speaking regarding Bayer Leverkusen was able to get the title at that time as I recall it was Tuchel's fault as Bayern Munich coach in a bad managing player and failed to create a consistent performance.
After that Xabi Alonso was able to see open opportunities and take advantage of these conditions to shift the position of Bayern Munich.
Now Munich has got a coach and player who is able to work together very well and there will be no gap for other clubs to try to shift his position
