I tried to watch two matches at the same time, Dortmund really missed a lot of chances in the second half, they tried their best, but Mainz defended with the whole team and they managed to draw as a result. Bayern played frankly badly, I can’t understand the reason for such a game, they almost didn’t attack, when the score became 1:1 they didn’t try to force things, but played as if they were already champions.
Borussia Dortmund had made the best effort they had, but indeed the flow of the game said otherwise, Mainz appeared so defensive that even Borussia Dortmund looked frustrated to score a goal. I also don't know what to say if Bayern Munich is just being lucky? because the second goal they made came in the final minutes of the match.
I don’t know if such Bayern deserve to be a champion, but the thing is that everything depended on Dortmund, if they couldn’t beat an unmotivated opponent in the last, decisive match, then probably everything ended logically, the champion should win in decisive match.
They deserved to win the Bundesliga title with all the efforts they made until the end of the season, I'm quite disappointed with Borussia Dortmund for not being able to win, instead of scoring goals, they even conceded 2 goals first.
