How much would you invest?
And Gladbach is in great financial shape, doesn't has to sell anyone and certainly isn't an online shop where you can go shopping as you wish.
We've still got quite some money from the last transfer window left(tried for Ginter, but Dortmund stepped in, same thing with Drmic and Leverkusen) and made some more thanks to TV money from EL etc.
Also: As I see the name Fabian Schar being thrown in here quite a bit.
He's been on Gladbach's list for quite some time and given that Ginter went to Dortmund and with our connections to Basel(Swiss coach, Xhaka, Sommer) there's a good chance he'll sign with us, IMO.
BTW: The first seven on your list wouldn't go for less then 20 mil, while Arnold's a pretty talented youngster playing for Wolfsburg, who don't look to sell at all and have a huge financial backing from Volkswagen.
