Unfortunately, as I've said in other threads, I feel there is most likely some sort of 'buying clause' inserted for Dortmund. I just don't see how this deal makes any sense for any party. If we wanted him to go out and get game-time, then we would hardly have sent him to a very in-form Dortmund side with a wealth of attacking options. The deal is so odd that the only logic I can see is a loan-to-buy deal of some sort. I hope it isn't, but I would be surprised if he comes back and plays under LvG.
