To be honest Ramsey isn't suddenly world class or anywhere near worth what he's being paid...but yes he's made a significant stride forward from last season. One because he's no longer being played in a deeper role because he can't track back or tackle, and two fair play to him when he has played he has worked his nuts off to counteract the fact that he isn't as technically gifted (anywhere near in fact) as those around him.
Very similar to Jordan Henderson, Henderson has been under pressure to justify his 20m price tag which of course he can never do because he doesn't have the natural ability or quality in his game, but he runs and runs and runs and works hard and it pays off for him.
Obviously Ramsey has to do a bit more in other areas because he can't run as he is too slow but there are definite parallels.
