Ignacio Trelles

In 1934, Trelles made his debut in Mexico's Liga Mayor with Necaxa. With Los Rayos, he enjoyed a golden era, winning three league titles in the 1934–35, 1936–37, and 1937–38 seasons, as well as lifting the Copa México in 1934–35. After his brilliant spell with Necaxa, Trelles joined Club América in 1943. Later, he was transferred to Monterrey. A true pioneer, he became one of the first Mexican footballers to try his luck in the United States. At that time, Major League Soccer did not yet exist, but small regional competitions were beginning to emerge, such as the National Soccer League in Chicago. In 1948, Trelles played for the Chicago Vikings. His career, however, was cut short that same year due to a severe tibia and fibula injury. He retired from professional football wearing the jersey of Atlante in 1948.

In 1950, Zacatepec gave Trelles his first big break. With the Cañeros, he began a remarkable journey, leading the team to a championship in 1951 and securing their long-awaited promotion to Mexico's top division. His talent quickly drew attention. In the 1953–54 season, Trelles captured his first Primera División title with Marte. Though his stint with Cuautla that same year was modest, his return to Zacatepec cemented his reputation as a top-tier strategist, adding two more titles in the 1954–55 and 1957–58 campaigns. This string of successes propelled him into the coaching staff of the Mexico national team as assistant to Antonio López Herranz, participating in the 1958 World Cup in Sweden. Soon after, Trelles took the reins of El Tri and left an indelible mark: in Chile 1962, Mexico celebrated its first-ever World Cup victory with a 3–1 triumph over Czechoslovakia. He also led the squad during the 1966 tournament in England. At the same time, Trelles managed Club América, guiding them to two runner-up finishes in the 1961–62 and 1963–64 seasons. In 1966, he took charge of Toluca and added two more championships to his growing legacy. His longest tenure came with Cruz Azul, where he spent seven years and won consecutive titles in 1978–79 and 1979–80, bringing his individual total to seven Primera División titles. He managed Atlante and Leones Negros before bringing his legendary managerial career to a close with Puebla in 1991.

Trelles was born in Guadalajara. As a child, he was very athletic, engaging in many different sports. In his teenage years, Trelles's family relocated to San Miguel Chapultepec where he regularly played football in the streets.

Trelles turned 100 in July 2016. He died of a heart attack on 24 March 2020 at the age of 103, in Mexico City.
