That's because with this system, Abate (inc Darmian) is extending while Motta is supposed to drop back. Abate hasn't been bad really. He almost scored at the end of the half and he has started the 2nd well.
I like Abate, but i'm also well aware of what Coentrao is capable of... If this goes through, I will not be that disappointed, although I still think DES is far better at left-back than he is at right-back.
