I really enjoy watching Fernandez play. He's got a good build for a full back and is quality on the ball with a high level of technical ability and potential for attacking end product.
However I don't get the sneering about highlighting the fact that his two weakest areas so far are his lack of great pace and his defensive work.
People would be wrong to dismiss his chances here just because he's, currently, weaker defensively. As the modern game has a place for quality attacking full backs / wing backs. But there's nothing wrong with, when asked what type of player he currently is, stating both the strengths and weaknesses at this stage of his career - that he's great on the ball but currently much better going forward than he is defensively.
Some people break into the first team at 18 - it's valid on threads like these to discuss the strengths and weaknesses of the players at that age and older, and about their chances of breaking into the first team here at some point (strengths) and how close they are to doing it or which areas in their game still need to be improved (weaknesses).
The comparison to [Irrelevant point] is a very good one so far.
