You know what's really impressive? Every team scored at least one goal this week, so all matches ended with goal/goal. If someone had bet that way, the win would certainly have been great, but that doesn't happen often. There weren't any big changes, Stuttgart has made it one place up and doesn't have to fight for relegation.
That was impressive indeed but you know, everything could happen in the last round 
Bayern and Leipzig getting a draw. Freiburg losing its EL spot after their defeat against Leverkusen, they will play Conference League instead.
Stuttgart survived and Hertha will go through relegation play-offs
