How has he improved defensively? He's a liability. Make him a winger or let him go. Whether or not you think he's a world class player, he hasn't been and shows no sign of being one, for us. I really don't get this stuff about how much he's improved. He has certainly improved over the last, say, five years perhaps, in total, but he has stagnated over the past 18 months at least and, defensively, is absolutely nothing like the quality we need in that position. Take the cash and laugh all the way to the bank.
Unfortunately I think there is little point in arguing with you. You've made up your mind about Chilwell.
