Even i am a big fan about Füllkrug and Haller i guess that one of them will be leaving the Club.
Donyell Malen and Guirassy together can be very good combination for Dortmund to get fast forward on the field.
I think when it comes to things like this, Dortmund always makes a good decision, and that is why they have been known for this. However, do you think Dortmund are going to be a very big challenge for Bayern next season? Furthermore, we have two Bayern in the Bundesliga competition, so are you talking about Leverkusen or Bayern Munich since those are the two Bayern we have? However, if you are talking about Munich, I don’t think Bayern Munich will be a very challenging for Dortmund, but Bayern Leverkusen will definitely be a challenge for Dortmund. Bayern Munich have a new coach, and their performance will definitely go back before they get strong again.
I don't really know why many people think that Bayern Munich's performances will decline or will not improve under Kompany as head coach next season. Kompany is not that experienced as a coach, but that shouldn't mean we judge him negatively. It would be better to allow the season to start and see their performances before rating Kompany as a poor coach. As for me, I believe that Bayern Munich will surely be in the race for winning the Bundesliga trophy next season. Bayern Munich will be a great challenge for Leverkusen, not to mention Dortmund. In fact, from my observation, I can't say if Dortmund will even be a good contender for next season's Bundesliga trophy, but let's see what happens.
