The Brazil captain felt he was harshly booked after missing out on a penalty during his side's rout of El Salvador in Washington
Neymar criticised referee Jair Marrufo after receiving what he felt was an "unnecessary" booking for simulation during his side's 5-0 win over El Salvador.
The Paris Saint-Germain forward saw yellow just before half-time at FedExField in Washington after failing to convince the official he had been fouled inside the penalty area.
While he did not complain at the time, the Brazil captain aired his views after the friendly fixture, declaring American Marrufo had made an incorrect call in showing a card, rather than his decision not to give a foul.
