I remember the saying that there is no "I" in team, but there is in WIN.
Football is a team sport, that very much depends on the individuals decisions and NOT their skills. The impact that you can give in every game is not how you score and how you defend, but rather how many times you have consistently given your team making those opportunities easier; offensively and defensively.
If you have watched the game of Germany vs Spain,
Xavi was this kind of player. Offensively, he is the facilitator of Spain's offense, making a lot of opportunities for them. Defensively, his position at center mid-field controlled Germany's counter-attack.
For every team or organization, there is a person whom people surrounds to. A person whom they look up to and shall follow without question. He may not be the most popular and famous person in the world, but you will know his influence, once you see him perform.
