I'd wager Walker has been responsible for half the goals we have conceded this season.
He never was the most technically proficient but even his supposed recovery pace isn't as pronounced this season.
He makes numerous bad choices and being asked to join up and make another man in the midfield is exposing both him and us horribly. He always turns inside and is never far away from a rash challenge, overrunning the ball or a bad tackle.
I personally don't like him and would prefer we went after someone we can rely on for the next five or six years, the lad Wan-Bissaka at Palace, he''l do for me.
