I don't know whether I'm supposed to feel worried that Cole may leave. But for some reason I don't and I rate him as the best in the world in that position. That could change when he actually leaves though.
He's infinitely better than any right back we have - and that's with his broken leg. It's hardly as though he can be classed as injury prone, given the fact that his two injuries have come from his leg being broken. I'd certainly hope someone can't be prone to broken legs anyway.
you can tbh. Not to a broken leg exactly, but you can potentially weaken points of the bone depending on how you heal.
