It is a financial waiting game. Be a lot of negotiations going on. There must be a price Everton will not go to. I would have it at a 1 year deal on 50 K a week.
21 in a few months with 0 appearances for the first team, doesn't really fill me with hope he's gonna be even good.
Likewise Okoronkwo, similarly player of the season for the U21s and scoring 4 in over 20 games in League 2.
I would keep him as backup. He's something like Maguire at Man U. Loads don't want him and yet when he plays he often contributes to the cause. Don't really mind if he does go though.
