Dortmund definitely has a very young coach with Nuri Sahin who will now certainly bring in modern new tactics and they are already making good transfers. With Guirassy they have got a top striker who will certainly be very effective for them. They just have to get a good player for the middlefield and otherwise the rest of their squad is already strong from last season.
Yeb he is very young for Coach and the best what happend to him is that he and the Fans know him already in Dortmund.
About the tactics i dont know if will be let playing a new modern one but with the transfers they will.
They have enough good players can fit in that role and maybe its time for some other young stars like Paris Brunner.
By the way Dortmund lost there second friendly game again.
