Normally, the logos of the team or the team sponsors are in the front and professional players earn a good amount of income on that
. Multinational companies offer players to have their company logos on the front or back of their football shirts as that would become a kind of advertisement board. The income of players generated from these sponsor logos depends totally on their popularity in the team and among the masses as companies normally prefer popular footballers so that their logo can appear maximum on the television screen. Many popular football stars prefer to auction their football shirts for some charity event or to raise funds for any other social cause.
