Borussia Dortmund use to be very consistent on there Bundesliga then but now a lot of things has changed about them, though Borussia Dortmund is well known in terms of generating a good players because the above listed names are currently doing very well on there current clubs.
Borrusia Dortmund have to spark their shining stars because that's the only path to bring them back to winning ways. It's never going to be easy for them because the board made huge mistakes in previous seasons. It's never been an easy road for Borrusia Dortmund, they sold all the potential talents and left with nothing currently. However we have nothing to worry about because they're always lucky to have in possession incredible young players.
The situation might be a little different because they just had a change of coach and some talented players moved to other clubs. Dortmund have to start from scratch this season because the players have to adapt again to the new coach and some of the newly brought in players also need time to adapt to the new atmosphere around them. The increasing competition in the Bundesliga will make it difficult for Dortmund to compete in the top four, Leverkusen is still a candidate for the title this season after achieving great success last season.
Bayern Munich are also starting to build their squad after a less than impressive performance under Tuchel, Stuttgart will also try to provide competition after finishing below Leverkusen last season. The competition in the Bundesliga is getting more interesting after Bayern Munich dominance was broken, now there will be other teams who want to follow in the footsteps of Leverkusen who have just won the Bundesliga. In my opinion, Dortmund still has the capacity to enter the top four, but the chances are very small.
