I don't think there's many people more interested in the tactical side of the game than myself so I completely understand the movement, constant changes of shape and rotation of players to keep the ball safe. Yaya is a master at that, when he's given time and space and not pressed.
The other side of the coin is when we lose the ball in vulnerable positions, Yaya's lack of mobility is suicidal in midfield, as part of a back three that get dragged out into fullback positions as well, 90% of the match going crowd would need a fucking defibrillator.
