For me, it was a sure win for Dortmund but for some odd reason that game against Mainz wasted in a draw right now I am doubting they could make another close win like this to the championship I think there is some reason behind Dortmund why they manage to draw that game against the Maiz, but I guess that is how it should be but right now Dortmund have traded Jude Bellingham to Real Madrid, and Raphaël Guerreiro but without information about his club yet, and I have some rumors that Bayern Munich would want their hand on Raphaël Guerreiro, and Mahmoud Dahoud would be transferred to Brighton and Hove Albion, so I am really doubting the strength of Dortmund next season,
there is no need to be in doubt for the long term about Dortmund because coach Edin Terzic certainly has a better plan to welcome the next season. it is impossible if Dortmund sells several players but they do not yet have a view of who is a better replacement to strengthen Dortmund's performance later.
and I'm sure that after Dortmund failed to reach the top of the standings, in this new season, Dortmund will immediately change the pattern of players and replace them with even stronger ones.
I'm just thinking about Dortmund's defense maybe needing to be replaced by some players who are not performing well. Dortmund often conceded goals last season because of a slightly sloppy defense
