Nope. Kovacic has potential to be one of the best cm in the world, technically very gifted, physically very good and defensively pretty good. But sometimes he made crazy pass or left his partner by himself too often. That need to be fix.
Azpi is doing fine. He is being asked to play as dynamic rb, he will suffer defensively. That is as expected, he is not exactly young anymore.
Zouma is also doing fine. It can be very painful to watch when he is on the ball but defensively he is fine. With proper midfield in front of him, I think he will look better. Plus our cb pairing are just too inexperience.
Willian is also doing fine other than his first match which was horrific. Against Sheffield, he came on and helped us big time in term of bringing the ball up.
