comparing Ramsey as a footballer to those around him is a joke, they may be playing poorly but he is consistently bad....as for this improvement you speak of, i've seen nothing out of the ordinary fare of miss placed passing putting us in problems by giving the ball away or conceeding a free kick with a poorly timed tackle.....other players don't give him the ball because they know they won't get it back....look at how when he plays with Wilshere, Wilshere won't pass to him.
The reason these other players are underperforming in midfield is because they are playing with Ramsey, every time we break on the ball the whole move is undermined by Ramsey who cannot run, cannot pass and cannot read the game....and i have not seen anything that suggests to me that there is any improvement no matter how small on that.
