Dortmund's performance has not improved, today's poor results indicate a bad era for a team that usually fights at the top of the standings. The defeat from Bochum certainly surprised many people because Dortmund is much stronger in strength but because of the loss of instability, their performance has worsened in every match.
Statistically, Dortmund was only able to dominate possession of the ball but doesn't mean anything because the final result was that they lost 3 points. Bochum was certainly very lucky because they were able to take advantage of Dortmund's instability to find points and they succeeded in doing so. Dortmund has many shortcomings in their performance this season, especially the defense line which is so fragile and the front line is not too sharp.
I think Dortmund must try to not make it worse. as such, the only thing left to do for the coaches and the managers is to communicate with the players and come up with tactical and technical plans and combinations
so that At best, they may have a team like the ones from the past in next season.
This season is going to be worst for Borussia Dortmund as they fail to increase their quality and also have consistency which is hurting them badly result like this is never been good for the team confidence which is important while their chances are high for having good results in Champions League but now with this level of performance they are not going to enjoy their next season in Champions League.
Change of coach is also not helping them for having better results with now they are at 11th and their difference with 4th spotted is 8 point mean it's going beyond their limit top teams are also losing their rhythm but still they are now having enough things for staying into top ranks, but Dortmund is surely needed good changed on time because in case of fail they will be down and out.
