Furthermore, in the last decades it has been noted that tools as the real market value or the reputation influence the ratings expressed on the players. Because of the complexity of the game of soccer, it is difficult to ascertain the relative importance of each of these variables and to establish an objective system for accomplishing a ranking of the best sportsmen.
