There is a gap in both sides’ quality.
Heidenheim are fighting for a spot of promotion this season, but they have suffered a dip in form at home.
As for Karlsruher, they are now stuck in the relegation zone, and now they should strive for points to get rid of trouble. But they are in poor form lately, with only 1 win, 1 draw and 6 losses in recent 8 league matches. Now they are only 2 points above the relegation zone.
Besides, Heidenheim are superior by grabbing 2 wins and 2 draws in their last 4 games against Karlsruher.
So Heidenheim should earn our favor in this home match.
