It's a name that's been doing the rounds for the last few months. He's played at the top end of the game, got to a WC final a few years ago with Croatia. So a very decent player, only 30 so still a few years left.
DS always talks about 2 players for each position. If we are going for 3 CBs you would have to expect left centre back is Mings and Hause. Centre of the three is Vida and Engels and right is Konsa and Chester.
