Ramos is one of those players that doesn't quite fit any position, at least, not at this point in his career. As a footballer, he's one of the most talented defensive players in the world, which emphatically does not mean that he's world class, though, unless we are going to start labeling players according to each attribute, or collection of related attributes, which completely ignores the reality of what a footballer actually is (i.e. the entire role that they fulfill, not part of it).
In time, as with Rio Ferdinand, his level of concentration will improve, as will his all-round defensive game, but he's still got a long, long way to go, and much further than Rio had at that age.
And the problem for Madrid (and Ramos) is that the areas that he needs to improve on the most are not likely to do so overnight (or even within a few years), regardless of how much effort he puts in on the training ground. Maturity, and all mental attributes, in general, can certainly be improved by a sustained effort, but we are a millions miles away from truly understanding the functioning of the brain, compared to our knowledge and understanding of the other areas of the body. That is why — at this moment in time, at least — unless you have a really innovative and knowledgeable coach, time is the only real guarantee that a footballer has, with respect to improving their mentality, and it is time that a footballer most lacks.
