It is generally difficult to associate numbers with positions, but in generally the number 10 refers generally to the field actors and playmaker of the medium
field players.
At Championship World Cup in 1954, teams were requested to use the numbering system. As a result new t-shirts were used and players were advised to keep the same jersey number throughout the tournament. Squad numbering system somewhat reduces the importance of numbers, but sales of football jerseys model of the World Cup teams increased dramatically this year. In 1965, the substitutions were introduced.
In 1977, the football team kits became very famous. The British were the first who started selling team shirts in bulk and quickly realized it was a goldmine.
At the beginning football shirts only had the player's number, during the final of the Premier League Cup, the first time the names of the players on the back of the shirt were printed. In 1993-'94 season shirts had two names and number of players in Europe, while Americans have adopted the same system in 1994 during the World Cup held in the states.
Since then, sales of the soccer team jerseys have skyrocketed. Today, all teams have sponsors and heavy contracts, so that their shirts are the trademark or logo of its sponsor.
