He was average previous season with flashes of quality, but little more than a Rodwell or Gosling, but you could see that in there he had the potential to become a Rooney.
I think this season he has made the leap from potential up to serious player.
I laughed when City bought Rodwel, didn't really care about losing Gosling, was made up we offloaded Anichebe because they were all potential that was clearly not likely to emerge.
Barkley is the real deal imo, was still potential last season, but has shown a bit more consistency and is having great games, instead of a few great moments in games.
Keep him till he retires a wealthy, trophy laden, Everton superstar
