In a niggly and fractious match, five-time Ballon d'Or victor Messi and Chile captain Gary Medel were given their marching orders eight minutes from half-time after tangling on the goalline.
Despite Messi and Medel both receiving their marching orders, it is unclear whether the Argentine's actions warranted a dismissal.
The game then erupted in controversy on 36 minutes when both Messi and Medel were shown the red card after a VAR check following an encounter between the pair.
Messi's frustration was evident in the mixed zone after what was only the second red card of his career.
"We leave this Cup with a triumph but above all with our heads up and with the feeling that this time football was not fair with us", Messi said in an Instagram post.
Neither Medel nor Messi raised their hands and the Chile man was the clear aggressor in the incident as both players saw red. "A yellow card would have been enough to put an end to it".
