DeAndre Yedlin was seen mocking Neymar during the USA's clash with Brazil on Friday, asking the referee if he "watched the World Cup".
Neymar won a free-kick from the Newcastle United defender during Brazil's 2-0 win, and Yedlin was unhappy with the way in which he hit the deck.
The right-back then turned to the referee and asked "did you watch the World Cup?"
That, of course, was a reference to the PSG star's alleged diving techniques used during the tournament in Russia, for which he came under fire.
Former Brazil international Julio Baptista claimed after the tournament that his diving can go too far , while countryman Ronaldo called on referees to offer him more protection.
