Barcelona midfielder Gavi and Real Madrid attacker Vinicius Jr clashed throughout this week's Copa del Rey semifinal.
Vini Jr scored in the 4-0 win as Real reached the final 4-1 on aggregate.
The Brazilian clashed with several Barca players, with taunts made to Ferran Torres.
And it's now been revealed he also had a running battle with Gavi. The pair traded insults and had to be separated at halftime.
Then in the second-half, after another flashpoint, Gavi stared at Vini Jr before grabbing his private parts in a clear insult.
However, Real's star scoffed in response, declaring: "You're out of the Copa. You're out of the Copa."
