If the Dortmund team is very unlucky or does not make a big mistake, then after 10 long seasons, the Dortmund team will be able to win the title again. Had Mainz been in good form, it might not have been easy for Dortmund to win the match. But Mainz is not in good form now. On the other hand, Dortmund's players are very confident now. More importantly, this is Dortmund's home match. The Dortmund team at home is very strong. And this is why I expect Dortmund to dominate and win against Mainz in the last match. It has been a terrible season for Bayern Munich.
Borussia Dortmund did not waste the defeat that Bayern Munich received the day before to RB Leipzig, Dortmund success in winning a landslide victory over Augsburg made the Bundesliga title race sure to be fierce until the last game. Dortmund victory over Augsburg made Bayern Munich lose the top of the standings, Dortmund threatened to break Bayern Munich dominance in the Bundesliga which they had mastered for the last 10 years.
Dortmund must win in the last game over Mainz which was held at Signal Iduna Park to ensure the title. This moment is very profitable for Dortmund because they will receive full support from their supporters to win over Mainz while celebrating their success in front of their supporters.
