Heh... I see you play Huth as the left central defender and Balanta as the right central but if you swap them then you'll get a great boost to your performance.
Balanta is left footed and when you play him as the right central defender then the most of time he can't make passes to the right flank and just clear the ball.
Huth is right footed and when you play him as the left central defender then the most of time can't make passes to the left flank and just clear the ball.
As I said just swap then and you'll get more possession and better performance.
Btw, Alvarez Balanta is a great transfer for any club and it's not just only because he is an awesome defender but he is also left footed which is rare so you can use him as the left central defender.
Usually clubs fight to death for a good left central defenders because they are rare and everybody need them so they always cost some "extra".
