Heidenheim is one of the strongest team in 2 Bundesliga , while Dynamo Dresden , which provides his first season in 2 Bundesliga now is going on the last place in the tournament table. Let's remember , how Heidenheim in past played against FC Bayern Munich and lose only 4-5. I think FC Heidenheim will win with advantage in 2 or even 3 goals.
Now HSV Hamburg as Arminia Bielefeld - two best teams in 2 Bundesliga. Arminia has already won his match against FC Bochum 2-0 and HSV need victory , HSV will play at home against 17 th place in 2 Bundesliga, but FC Nürnberg in last season was in Bundesliga and it won't be easy match for Hamburg.
Stuttgart have won four of their five home games this season and coach Walter will be looking for a reaction from his side after their first defeat of the season. They will return to the top with victory and there is the added spice of Kiel being Walter's former club, so expect a home win.
