Barcelona winger Pedro attacked Real Madrid star Cristiano Ronaldo during Monday's El Clasico.
During the infamous bust-up between Ronaldo and Barca coach Pep Guardiola, Pedro was the most aggressive in the aftermath of the all-in brawl.
El Mundo Deportivo says Pedro screamed at Ronaldo: "Who are you? WHO ARE YOU?" during the push-and-shove.
His approach even shocked - and impressed - his Barca teammates as they sought to put former Manchester United star Ronaldo in his place after weeks of bad-mouthing the club.
