Don't think that's true. People have been going crazy over someone like Wilshire ever since he held his own vs a Barcelona midfield at the peak of its powers. I'm not sure he has more goals in his career than Barkley does to date, but he is extremely highly regarded for what he brings to the table.I think it appears over the top given the type of player he is. Players like Rooney/Bale etc., will always be the poster boys because they're scoring wonder-goals and are capable of those special moments on a reasonably consistent basis, whereas players like Barkley who are the ones who are more 'tidy' and have a different type of game so to speak will be overlooked.
It's like the Scholes/Gerrard/Lampard argument in a way when people overlook Scholes.
Barkley clearly has talent and potential, but he has also been overrated a fair bit in relation to his performances to date. He's been good thus far, not stellar.
