Antonio Ubaldo Rattin, one of Boca Juniors' most iconic midfielders, has died at 89. The club released a tribute, calling him an idol and symbol of its identity. Rattin spent his entire playing career with the Buenos Aires club and earned national caps for Argentina.

Between 1956 and 1970, he made 382 appearances and scored 28 goals, lifting the team to four league titles and a Copa Libertadores final in 1963. He represented Argentina from 1959 to 1969, adding 20 caps.

His 1966 World Cup sending‑off against England sparked a change. After a dispute with German referee Rudolf Kreitlein, Rattin refused to leave the field, tore an England corner flag, and sat on a red carpet reserved for Queen Elizabeth II. FIFA responded by introducing the red and yellow card system at the 1970 World Cup to eliminate communication barriers.

Following retirement, Rattin had a brief coaching stint at Boca before entering politics. His death marks the loss of a player whose actions reshaped international football and whose legacy lives on in Boca's history and the modern disciplinary system.
