Bally was like that, but he ran around as well. Balls greatest skill was that he could the simple things well...pass, read the game etc., but he was also a runner and a tackler. Barkley can do the simple things very well(if he has the time) but he is not half the player that Ball was because he does not have any of Balls 'zip'. I know I'm not comparing contemporaries but I think people will see were my opinion is coming from.
Again, statistically by two analysis sites, he's playing at a very high level - and he is.
Comparing to a player 40 years ago is daft. The game is completely different, played at a different tempo with different roles.
Barkley does what nobody else in the team does. The job you're describing is the work of James McCarthy, not Ross Barkley. Ross retains possession, keeps play moving and moves into clever attacking areas to upset a rigid defence.
He's a Rolls Royce of a footballer, after decades of Everton being used to a more industrious player in his role like Tim Cahill, and as such Evertonians don't understand what he does.
This is doubly the case when we're struggling as an overall side. Because we're so often chasing down results, Barkley's lack of "headless chicken mode" comes across as lacking - but if you put Ibrahimovic in our set up, he'd look the same, but that wouldn't be an indication of his quality as a footballer; it'd be more of an indication of our stupidity as a side.
He'd walk into absolutely any side in English football in his position, and outside of Barcelona, Real Madrid and Bayern Munich he'd be an automatic starter for any side in world football.
