Juan Domingo Perón's death is showed when Maradona is aged 9, which should have been between 1969 and 1970. However, Perón died in 1974.
When Maradona goes to the try outs for a children team, It is (correctly) stated that he was born in 1960 and he was 9 years old at the time. Moments later, without time skips or anything, his mother is seen learning and mourning the death of president Juan Perón. In truth, Perón died in 1974. In 1969 there was a dictatorship in Argentina, which had banned any mention of Perón.
