I expect Heidenheim and Hamburger SV both win their games. Regensburg and Sandhausen are both relegated. But that can also become a problem. It is often the case that such teams then perform much more better because the pressure is off. We saw that in the last game between Hamburger SV and Fürth. Fürth could no longer be relegated and did not play so tense as the games before.
But even if Hamburger SV lose they remain at place 3.
130 minutes to go and the grand finale begins. who will be the direct second promoted team ? will heidenheim or hamburger sv make it ?
normally heidenheim should win in regensburg. but hsv also has to win in sandhausen. as you have already written:
i think both teams will win their games and hsv will have to play vfb stuttgart in the relegation. but that will be two really interesting games.
both stadiums will be sold out and one team will stay or come in the 1.bundesliga at the end.
but as always: at 5:25 p.m. today we are all smarter and know the results
edit 5:40pm
1.Heidenheim
2.Darmstadt 98
3.Hamburger SV
