Edimilson Fernandes and Tonny Vilhena have been linked with BMG recently, both are interesting...though I would like to know more about how Vilhena's developed these past few years. Grilitsch is the young 6 that I really want BMG to get to fill Xhaka's spot, since he can step right in at the BuLi level, but Fernandes is a very intriguing talent who seems to have quite a bit of Xhaka's strengths in him...though he's certainly more of a signing for the future. I'd like to see both join BMG, even if they make further moves that would allow Dahoud to take over more of Xhaka's responsibilities.
Vilhena seems like he'd be a signing more in that latter mold; an alternative to Kramer or Amiri/Stendera/Betancur who would let Dahoud move into a more Xhaka like position.
With Volland set to decide his future by the end of the month, BMG seem to be on their way to another fantastic season if they pull these moves off.
