Well, it's worth saying that Hamburg was definitely unlucky this year with promotion to the Bundesliga, because their competitors turned the course of their match in the time added by the referee in the right direction for themselves, although the whole match score was in favor of Hamburg. Therefore, I perfectly understand the chagrin of the Hamburg fans, who joyfully ran onto the field after the Hamburg match, and then it turned out that Hamburg would have to fight for promotion further, which the club then successfully failed. Although, of course, with such a budget, Hamburg had to solve its problems much earlier and not bring everything to such a deplorable finish.
the last time a third-placed team in the 2.bundesliga had 66 points and didn't get promoted was in the 2016 / 2017 season.
braunschweig also had 66 points then and only came third. and braunschweig didn't get promoted then either.
they lost the two relegation matches 1:0 to wolfsburg in each case. since 2017, every club with 66 points has been promoted to the first bundesliga ....
only hamburger sv didn't make it because 2 teams were better. and next saison they are trying again. and again with a very good budget
