Football, as a sport played by the masses, started late in Puerto Rico's history. There were several amateur tournaments and leagues throughout the second half of the 20th century, but it wasn't until 2008 when the first professional football league was started. Here is an incomplete list of champions in Puerto Rico's football history.
The "Asociación de Fútbol de Puerto Rico" (Puerto Rico Football Association) existed for a single season (1996) with teams from San Juan, Yabucoa, Caguas, Maunabo, Guayama, Ponce, Cabo Rojo, Mayagüez, Aguadilla, and Arecibo.
In 2005, a united national championship was organized by the Puerto Rico Football Federation, the "Campeonato Nacional de Fútbol" (National Football Championship), but it was composed mainly from teams from the LMF.
In 2008, the first professional league was created, the Puerto Rico Soccer League (PRSL), which was composed of eight teams playing the regular season, and the top four seeded moving on to the playoffs. A ninth team joined in 2009, three teams joined in 2010, and one team joined for the 2011 season, after which the league folded. The new professional league, the Liga Profesional de Fútbol de Puerto Rico, is scheduled to start in 2013.
3The 2011 championship match had only one leg. After 120 minutes, the game was decided in favor of FC Leones de Ponce, who were able to successful convert its first three penalty attempts and, also, were able to stop all three attempts from Sevilla FC Juncos.
In 2008, along with the first division, a PRSL 2nd division tournament was organized, anticipating a promotion/relegation system, which was scheduled to start in 2011, but that was postponed till 2013. In 2009, the Puerto Rico Football Federation renamed the 2nd division league "Liga Nacional de Fútbol" (National Football League) and made it a separate amateur league. The 2008 season had eighteen teams divided in three groups; the 2009 season had sixteen teams divided in two groups; while the 2010 season had twenty-one teams divided in four groups. For the 2011 season, the LNFPR split into a first division with eight teams and a second division with 14 teams, retaking the promotion/relegation ideas, which is to start in 2013.
