This season Borussia Dortmund has not performed badly. They have won one game and drew one in two games. They are even better than Bayer Leverkusen which has just three points in two games. They have a new coach, Nuri Sahin, who is not new to the Bundesliga, having worked as an assistant coach in Dortmund before he was appointed head coach. Four points from two games is not that bad, and hopefully, they will improve after the international break.
Borrusia Dortmund is mainly for winners, although the team's management have made major mistakes that have made them experienced setbacks in league games, talking about selling players, not just any players but the rare gems that have top talents to drive the team to specific heightened station. This is still early stage to start predicting the club's to win the Bundesliga title because every elite clubs are having some up and down moments. This is Germany and the main clubs are preparing to having consistent performance this season.
Borussia Dortmund is one of the strongest teams in Germany. They are one of the strong candidates for the championship again this year. I think they are using the players in the best way to be a better team. It is too early to comment on this season because we are still at the beginning of the league but I am sure they will be one of the candidates for the championship again.
