VIDEO: El Clásico rivalry rears its head during friendly match in United States

It only took one former Barcelona player to reignite El Clásico rivalry Tuesday night between Roma and Real Madrid during the Guinness International Champions Cup in Dallas, Texas.

Before the match started, Roma's Seydou Keita refused to shake the hand of Real Madrid defender Pepe because of bad blood between the two while Keita was a member of Barcelona, Real Madrid's fiercest rivals.

Keita, who spent four years at the Nou Camp, was fuming afterwards and even threw a water bottle that barely missed the grinning Pepe as he removed his gear in preparation for the match.

One report claims that the feud dates back to when Pepe reportedly called Keita a monkey during a 2011 Supercopa Clasico encounter between the two.
