San Lorenzo de Almagro

Father Lorenzo Massa, honoured by the founders giving his first name to the institution

The roots of the institution are a team formed by a group of children that played football in the corner of México and Treinta y Tres Orientales streets of Buenos Aires. Due to increasing traffic in the city, playing football in the streets became a risky activity for the boys. Lorenzo Massa, the Catholic priest of the neighbourhood's church, saw how a tram almost knocked down one of the boys while they were playing in the streets. As a way to prevent more accidents, he offered the boys to play in the church's backyard, under the condition they go to mass on Sundays.

On 1 April 1908, an assembly was held in the Almagro district of Buenos Aires with the purpose of establishing a club. During the meeting, several names were proposed. The first option was "Los Forzosos de Almagro" ("The Strongmen of Almagro", the name used by the boys for their street football squad), which did not sound good to Father Massa (who was present). The other proposal was to name the club "San Lorenzo" as an homage to Massa, but he declined to be so honoured.

Nevertheless, the name was finally accepted by the priest, explaining that the name would not honour himself but both Lawrence of Rome ("San Lorenzo" in Spanish) and the Battle of San Lorenzo, one of the most significant combats for the Independence of Argentina. Another founding member, Federico Monti, suggested to add the name of the neighbourhood, Almagro where most of the members lived, which was accepted by the assembly.

Due to the team not having its own a stadium, San Lorenzo began to play its home games in a field of the Club Martínez, placed in the nearby town of the same name. The squad played its first match on 26 April 1914. At the end of the season, San Lorenzo had to play a final match against Excursionistas to declare a champion. San Lorenzo won the series (the results were 0–0 and 5–0). This title allowed San Lorenzo to enter the playoffs in for promotion to the Argentine Primera División, which was finally obtained after beating Club Honor y Patria by 3–0.

San Lorenzo began to play in the Argentine Football Association tournaments on 26 April 1914 in the second division, where the team finished sharing first place with Excursionistas. As a result, both teams played a two-match series to determine which team would proceed to the playoffs. San Lorenzo won the series after thrashing Excursionistas 5–0 in the second game.

In playoffs, San Lorenzo eliminated other teams before playing the final against Honor y Patria, winning 3–0 and being promoted to Primera División.[9]´

San Lorenzo made its debut in Primera on 4 April 1915, losing to Platense by 5–1. The first match won in the top division was the 7th fixture, when the team defeated Floresta by 3–1. San Lorenzo finished 12th at the end of the season, tied with Gimnasia y Esgrima de Buenos Aires.[10]

On 7 May 1916 the club inaugurated its first stadium (popularly known as "Viejo Gasómetro" during a match against Estudiantes de La Plata, which San Lorenzo won by 2–1. That same year, the team finished 7th in the Primera División championship. In subsequent tournaments the team did not wage good campaigns, finishing 12th[11] and 13th. In 1919 the Argentine league split into two leagues, the official Asociación Argentina and dissident Asociación Amateur (AAm),[12] in which San Lorenzo took part, along with Racing Club, River Plate and Independiente, among other teams. San Lorenzo finished 9th.

The San Lorenzo team that won its first Primera División title in 1923

In 1920 and 1922, San Lorenzo finished third, finally winning its first title in 1923. The squad won 17 of 20 games, only losing 2. San Lorenzo scored 34 goals in 20 fixtures, conceding 13.[13] That same year the squad also won its first international title, The Copa Campeonato del Río de la Plata after beating Montevideo Wanderers 1–0 in the final.

San Lorenzo won its second consecutive Primera División title one year later. The team played 23 matches winning 18 with 2 losses, with a total of 48 goals scored and 15 conceded.[14] In the following two seasons (1925 and 1926) San Lorenzo would make great performances finishing 2nd to Racing Club and Independiente respectively finally achieving its 3rd title in 1927, when both leagues AAF and AAm had joined again. The squad totaled 57 points in 33 matches played with an outstanding mark of 86 goals scored (2,60 per game) and conceding only 26.[15]

The 1927 team won both the Primera División and Copa Aldao championships

Apart from winning the domestic league, in 1927 San Lorenzo won its first and only Copa Aldao, after defeating Uruguayan team (Rampla Juniors) by 1–0. The club soon became one of the most popular institutions in Argentina, increasing its number of followers and being counted in the top five (cinco grandes) together with Boca Juniors, Independiente, River Plate and Racing Club.

The team that won its third league championship in 1933

In the 1930s, Isidro Lángara and other players of Basque descent endeared San Lorenzo to the Basque community. The team also relied on players from the provinces, known as los gauchos. San Lorenzo returned to success in 1933, when the team won its 4th league championship. The squad totaled 50 points with 22 wins, 6 losses and 6 draws. San Lorenzo scored 81 goals and conceded 48. Boca Juniors was the runner-up while Racing Club finished 3rd.

In 1936, there were two championships within the year, in a format of single-robin tournaments. San Lorenzo won the first round (named "Copa de Honor" for the occasion) while River Plate won the second round ("Copa Campeonato"). Although titles were recognised as official by the Association,[16][17][18][19] both champions, San Lorenzo and River Plate, had to play a match (named "Copa de Oro") in order to define which team would play the Copa Aldao match v. the Uruguayan Primera División champion. Finally, River Plate won the game by 4–2 and qualified to play Peñarol.

San Lorenzo league champion team in 1946

In 1943, San Lorenzo won the national cup, the Copa General Pedro Ramírez, named in honor of Pedro Pablo Ramírez, the de facto president of Argentina by then. San Lorenzo won the trophy by defeating General Paz Juniors 8–3.

After the 1936 success, San Lorenzo would not win a league title for ten years, when in 1946 proclaimed champion with a total of 46 points (the runner-up, Boca Juniors, finished 2nd. with 42). San Lorenzo also scored a record of 90 goals in 30 games played, only conceding 37.

That same year (1946), the team went on to a tour of Spain and Portugal that was one of the highlights of the club's history. The team debuted playing Atlético Aviación winning 4–1. San Lorenzo played a total of 10 matches in Europe, with some extraordinary victories over the Spanish national team (7–5 and 6–1). The Spanish crowd at the stadium acclaimed San Lorenzo as "Son els millor del mon" ("You are the best in the world" in Catalan). San Lorenzo then moved to Portugal where the squad showed its skilled play, thrashing Porto (9–4) and the Portugal national team by 10–4. The only team that defeated San Lorenzo was Real Madrid by 4–1.

As a result of the successful tour, player René Pontoni was offered a contract with Barcelona, but declined to leave Argentina (Barcelona then drafted River Plate's Alfredo Di Stéfano). Fellow player Rinaldo Martino did stay in European football and would later become a star with Juventus.[20]

In the 1960s, a generation of players known as carasucias (literally: dirty faces) were the darling of Argentine fans because of their offensive, careless playing and their bad-boy antics off the pitch. The 1968 team was nicknamed los matadores as it won the championship without losing a single game. This team was recognized as the best team in the world by many journalists. In the years 1968–1974 San Lorenzo won four league titles, its best harvest ever. In 1972, the club became the first Argentine team to win two league titles in one year.

Poor administrations, however, led San Lorenzo to a huge economic crisis. Argentina's military government coerced the club into selling the historic stadium located in Boedo. The team was relegated in 1981, only to return to the top division with great fanfare in the 1982 season, which set all-time attendance records for the club.

By that time, the club had no stadium and was plagued by debt and irregularities. Controversial president Fernando Miele (1986–2001) delivered both the new stadium and two league titles: the Clausura 1995 (after 21 years without winning a first division title) and the Clausura 2001 (in which the team achieved 11 consecutive victories). San Lorenzo finished the Clausura 2001 with 47 points in a tournament of 19 matches, setting the record for the highest points haul since the inception of the Apertura and Clausura system in 1990.

In late 2001, San Lorenzo won their first international title: the Copa Mercosur 2001, becoming the only Argentine team to win that international cup, because the others champions were all from Brazil.

San Lorenzo also won the first edition of the Copa Sudamericana, the 2002 edition, beating Colombian club Atlético Nacional in the finals. This was their second international title, which gave them the opportunity to play the Recopa against the Copa Libertadores champion, Paraguayan club Olimpia. In the 2003 Recopa played in Los Angeles, United States, San Lorenzo lost to Olimpia 2–0 and finished runner-up.[22]

In June 2007, San Lorenzo won the Clausura 2007 league title, beating Boca Juniors in the race for the title by 6 points, even though Boca had beaten them 7–1 in the Apertura 2006.[23] Led by manager Ramón Díaz, San Lorenzo secured the title after the 17th round of fixtures, with two games still left. They finished the tournament with 45 points.

A San Lorenzo team of 2015

Six years later, and only one year after being relegation-threatened, the club managed to win their 15th league title, Torneo Inicial 2013.[24]

In 2014, San Lorenzo won their first Copa Libertadores.[25] They began their campaign by finishing second in its group. In the knockout stage, they beat Gremio on penalties, Cruzeiro, and Bolivar with a very one sided 5–1 aggregate victory in the semi-finals. In the finals, they defeated Nacional of Paraguay 2–1 on aggregate, concluding their championship run with a 1–0 victory in the second leg at Estadio Pedro Bidegain. This earned the club a berth in the 2014 FIFA Club World Cup in Morocco, their first trip to FIFA's premier club tournament.[26] They would ultimately lose in the finals to Real Madrid, and finish as runners-up.[27]
