Borussia Dortmund have made a mediocre start to the Bundesliga this year and they are fourth in the League table eight points adrift of league leaders Bayern Munich.
It will be interesting to see if the German side can regroup and launch a proper title challenge during the second half of the season.
Key areas that need strengthening
Borussia Dortmund have an impressive attack at their disposal but they need to improve on the defensive front.
They have lost five of their 14 league games and have conceded 18 goals in the Bundesliga so far.
