Bundesliga has 5 clubs in the champions league.
That's would be first time in the history that usually Germany has 4 spots for champion league but because Frankfurt has successfully became the champion of Europa league then they will automatically play at champion league although they were finish at 11th last season so for next season Bundesliga teams who playing at European competitions is 8 teams but i don't know they will have good achievement or not because besides Bayern the teams who playing at champion league such as Dortmund, Leipzig or Leverkusen only became an the underdog
Yep, this season could be a season that is quite difficult to happen again at any time because indeed 5 clubs is something that is difficult to happen in the Champions League for a Bundesliga club.
But even if there are many I wouldn't expect much like that because for the Champions League it is clear that all the great clubs are there and even though there are quite a few Bundesliga clubs, maybe in the end only Bayern can talk a lot there.
