Nelson!
Striker
Agree that he's likely to leave and I doubt there's much more in the way of potential there. Peterborough fans warned us that he was error prone. What you see now is pretty much what you'll get imo.
They said he was great and then struggled after being made captain. Iirc his family also told someone off here the fan perception gets to him and knocks his confidence.
That aside I think he's a good defender, prefer him to Flanagan as I said.
I'd give him a chance in a roll where someone else takes the reigns ala Evans and Nuggsy.
