Sabrina wants to get better at soccer. In order to do this, she has created a list of skills she will need to improve. Which skill should get the most of her attention in order for her to excel at soccer?

I will answer your question but i will not choose between your choices, if it has one, so i hope you consider it. In playing soccer, like all field related sport, one must consider its basic fundamentals fist. Second you must improve your stamina, agility and most of all your kicking skill, not just force but also be more intellectual in playing. Third is never give up on trying and work hard on what your are doing.
