Dortmund should win this one easily, Heidenheim is a very small team but they had a good run lately. They have 6 games unbeaten streak, that have to end some time and it could be today. Dortmund won their last 3 games with high scores, they have no problem about scoring. They only conceded one goal in these three matches so they don't have any problem in defense as well. All signs show that Dortmund should win the game, odds also reflect that. They need to be closer to Leverkusen and Bayern as the point gap is too much now.
For me, the two teams that will compete in a few moments have almost the same similarities in their five matches in the Bundesliga. Heidenheim, who will currently compete as the home team, has only won two of their 5 matches. even so, the last three matches they played ended in a draw. meanwhile, Dortmund, the team coached by Edin Terzic, only had two draws previously. after that, Dortmund started a three-game winning streak. so, these two teams are both unbeaten in their last five matches. But, that's not the problem we're going to discuss.
IMO, I am quite sure that Edin Terzic's team will continue its positive trend and win over Heidenheim. Referring to several sources that can be my reference, it looks like there will be 2 options that Edin Terzic will implement in this match. Terzic could have used a classic 4-3-3 pattern, or a 4-2-2-2 pattern. which means, there is a striker duo on the front line, namely Fullkrug and Maukoko. If the pattern is classic, it means Fullkrug remains a pure sticker. what is certain is that currently Dortmund is motivated to shift Stuttgart's position, which is in 3rd place.
While the home team, Heidenheim is predicted to use a 4-2-3-1 pattern. in fact, as the home team, Heidenheim certainly wants maximum results. at least, the worst option with minor results. aka, share 1 point. But my estimation, Dortmund will win this match. at least odds @1.76, ideal enough to choose Dortmund in this match.
