If our system does not need his particular talents then our system is basic and horrible.
What you're suggesting is that you'd just want Everton defenders to boot out the ball every time it comes near. That sounds horrible.
The difference between the way we play now, scoring loads and conceding one more, and hopefully eventually scoring loads and conceding very little – all it will take is a little bit more time and a few tactical tweaks.
Ridiculous to suggest to get rid of the best young ball-playing defender in the game because you'd rather have an Ashley Williams.
