It's a really good move for Bayern, and it hopefully means Boateng has more than one foot out the door.
Plus it's another solid backup behind Alaba. With Pavard coming in next summer, they'll have some versatility and depth between DM and the back line.
Also, this is nearly double Bayern's biggest transfer buy ever.
Uli/KHR just silent about it when asked, somethings up. This is one of those sneaky Tolisso type deals where you're like "Wow".
Now do this with a winger.
