I think you are over thinking things a little. The club is bound to have more than a few irons in the fire to cover all eventualities. No reason it can't go for both.
Probably re-hashed news but interesting that this one keeps rumbling on.

The translation was saying he's maybe playing both the interested parties in England and Dortmund. I'll look for the translated article.
Edit: here's the article:
The case of Thomas Delaney is tricky. MY WERDER provides an assessment of what's going on at the change poker for Werder...
This one is a weird one. Perhaps more twists in the offing:

That's a strange logic. You seem to suggest you are only interested in finding out whether he would have been a great buy once news comes in that he won't be our player.
And why not read the thread instead of asking after the horse has bolted?
Genuine question. Why has it taken 430 posts and many, many months, for you to ask the question? Especially in the light of the recent news that he is almost certainly going to Dortmund.
Actually, I edited my post as the tweet was misleading, it implied he was having a medical but the link was about several players, one of which, a defender, was having the medical.
Oh dear.

Seems to be going to Dortmund.
Edit Just seen I misread about the medical. That wasn't for him.

There is also a contradictory report that says he has agreed to join B. Dortmond.
