I'm surprised most people are surprised about King being released.
We've got decent centre backs and the fact is - King is too good just to be 'cover' (as most people on here see him). He probably would take a decent payment if he did play and would he stick around on the bench?
I think a more urgent need is a striker. Pugh will go back one day and then we'll struggle to get goals. Pugh going will happen 100%, centre backs getting injured might not. If they do then I'm sure cover will be drafted in.
