Being selfish I would like to keep him for another season as I think he has the potential to develop into a top top player.
On the other hand, I do think we are pricing him out of a dream move to Everton and are holding him somewhat to ransom.
After the 2nd half of last season, I dont think he is the type to get his head down and work hard if he isnt 100% commited. For that reason I would snatch Evertons £35m offer and reinvest the cash in 2-3 solid signings to help us get back up.
Free the boy and then back the manager in the market.
