So here is a piece of news we weren't expecting to hear: Sean Davis is apparently hanging out with Brother Leipzig's U-23 team:
@Once_A_Metro Sean Davis appeared today in a friendly for the U23 in Leipzig. Can you say something about the player?

And...that's about all we know at the moment.
Before the rumor mill gets too excited, it should be pointed out that Matt Miazga trained with RB's Leipzig and Salzburg during last year's off-season, and he went on to play a full season with the New York Red Bulls (and may yet contribute to RBNY's 2016 campaign).
