Nah, leave Nelson there. Unless we ship a load out, which we inevitably won't. I think Nelson will be in a position to challenge for a place in our 11 next season regardless of division rather than be cover. No point in him coming back to be utilised in the same way Vesty and Coady are, and you know he'll be behind both in the pecking order.
Speaking of Cover; he's is doing very well but what's the next logical step? If Port Vale get promoted have him play for them in League 1? Cos that doesn't seem worth it from our POV. So a champ loan (hopefully we're not in a position to offer champ football ourselves)?
