Soccer, also known as soccer in America, is arguably the most popular sport in the world. Among hundreds of professional football leagues, the English Premier League, the Spanish League and the Italian Lega Calcio Serie A are the best known. The English Premier League (EPL) is considered the best because hundreds of world-class soccer players play in this league. Now, however, LaLiga is beginning to rival the EPL because many Spanish teams have begun to ‘buy’ talented players.

The presence of superstar players in a soccer league really makes a difference in the overall atmosphere of the competition. Take American Major League Soccer, for example. In the past, MLS didn’t get much attention from Americans. But after the arrival of David Beckham, who is a living legend of English football, MLS has become more and more popular.

Today, football is no longer about the games we watch every weekend. It has become a huge industry where billions of dollars circulate within it annually. Professional gamers have become celebrities because they have thousands of fans and also because of their glamorous lifestyle.

One of the most talked about topics among football fans every year is player transfers. The most recent and phenomenal move was the transfer of Fernando Torres earlier this year. Chelsea Football Club paid £50m for him to leave his former team, Liverpool Football Club, making it the most expensive transfer in EPL history.

The concept of player transfer was introduced by the English Football Association over a century ago, with the purpose of supporting professionalism in football. The regulations state that before a new season begins, all teams must register all players with FIFA, which is the international governing body for soccer. All players registered in one team cannot be registered in other teams. Player transfers are not allowed to take place outside of the ‘transfer window’. The transfer window is the period in which football clubs can recruit players from other clubs to be their players.

The move is complete when the new team has registered the new player with FIFA. There are two windows: one before the new season starts and one in the middle of the season. The schedules depend on the regulations established by the soccer authority of each country, but they generally last the same amount of time for all the leagues in the world.

Generally, a club can buy players who are not bound by any contract with another club. But in some cases, two clubs can negotiate transfers of players who are still under contract. The move can be made as long as the negotiated terms are met.
