The incident occurred as Vinicius was substituted in the second half of the 2-1 victory that booked Real a spot in Sunday’s final against rivals Barcelona.
Goals from Federico Valverde and Rodrygo secured Xabi Alonso’s side’s win, ending Atletico’s hopes of silverware.
However, the match was overshadowed by the heated exchange between Vinicius and Simeone on the touchline. Television cameras captured Simeone telling the Brazilian forward: “Florentino is going to fire you, remember that later,” according to Mundo Deportivo.
Meanwhile, Barcelona had already secured their place in the final with a 5-0 win over Athletic Club and will aim to defend their Super Cup title against Madrid on Sunday.
