Barcelona coach Xavi mocked Real Madrid fullback Dani Carvajal during last night's win.
Barca won the first-leg of their Copa del Rey semifinal 1-0 in Madrid.
During the match, Carvajal and Barca's Alejandro Balde clashed, with the pair grabbing eachother's arms.
Xavi was angry as Carvajal demanded Balde be booked.
"You're very clever," snapped Xavi, before making a gesture suggesting Carvajal was talking too much. The coach then reacted, saying: "Moron, you're a fool."
