He keeps losing the ball.
So does Gundo.
When the legs are gone you find you don’t have the time you used to have. Getting caught in possession, diddering about, not making a decision.
Poor decision making has us repeatedly cheaply losing possession. One ball through usually opens up and panics our defence.
Akanji and Gvardiol, to my mind, are not natural defenders. Gvardiol is decent going forward but that’s it.
I would regard Ake as the most naturally defensively minded player we have available and he doesn’t seem to be 100% fit.
