Are you saying you know more than Klopp, etc?
Anyway, maybe he did. He certainly had blind spots. This may shock some posters to hear, but it is possible that Slot does too.
I like Elliott. I think there's too much technical ability to readily discard. Scholes was the most unathletic player around and he took a long time to really mature.
Sometimes it's also about just keeping the player warm while he develops. I don't think Jones makes it without the vast patience Klopp afforded him.
