Just look at the example of Dortmund last season where they almost won the Bundesliga, but because they were unable to play well to get full points, Bayern Munich took the championship again. Even though Dortmund only needed to win in the last match and the match also took place at home.
High self-confidence is needed and a winning mentality, it seems that Dortmund in that match were not really confident and did not have a winning mentality so they failed to win the match they should have won and won the Bundesliga last season. Obviously this made many of their fans disappointed and came to watch at that time. Playing at home showed disappointment in the players because they failed to become champions.
But I think they will learn from previous failures even though this season doesn't look better than last season because there is another club that will be their biggest challenge apart from Munich, namely Leverkusen, where currently they are playing very consistently at the start of this season, they may also have a chance to win. league this season.
