I'd rather hold onto Kiwior while Mosquera settles. I'm not sure our centre back cover being a 21 and 19 year old, neither of which have any PL experience, is really a great idea. Kiwior has finally reached the stage where we want him to be, give him another year before we cash in. This is our "win now" moment, don't think there's much to lose holding him for now. How longs he got left on his deal?
