Messi told the official, "Speak to me properly. Don't disrespect me. Speak to me properly. I spoke to you properly."
Despite this tense moment, the exchange remained controlled. The Argentine captain kept his composure throughout the discussion, while Pinheiro chose not to issue a yellow card or any other disciplinary action.
The match continued without interruption, although the clip quickly spread across social media, sparking widespread debate among football fans.

Switzerland, who had been reduced to 10 men, bowed out after an impressive campaign, while Argentina moved a step closer to retaining the World Cup title.
The victory keeps alive Argentina's bid to become the first nation since Brazil in 1962 to successfully defend the FIFA World Cup.
