Mauricio “Shogun” Rua is a proud Brazilian, and feels it is his duty to make Chael Sonnen pay for his recent comments.

Sonnen, never one to keep his mouth quiet, has called out Rua’s fellow countrymen like Anderson Silva, Antonio Rogerio Nogueira and Wanderlei Silva several times. Rua and Sonnen are set to collide this August in the main event of UFC on FS1: Shogun vs. Sonnen.

“The motivation is great,” said Rua to TATAME. “He disrespected [Antônio] Nogueira, Wanderlei [Silva]. About me, he still said nothing. But disrespecting Wanderlei is enough. He is a controversial guy that really likes to talk a lot, but I’m cool. Sonnen will surely want to say something to me, but it does not affect me at all.”

Rua was originally scheduled to face Nogueira, but a knee injury knocked “Minotoro” out of the planned bout. Sonnen agreed to step in, but visa issues kept him from fulfilling the obligation earlier this month.
