Young, undefeated prospect, Guilherme Bertholdo happens to be the nephew of Anderson Silva, the man many consider the best pound-for-pound fighter in mixed martial arts today. With that comes pressure to perform as Berholdo will look to keep his undefeated Muay-Thai record of 6-0 going against Chris Lazaro (7-2) at Lion Fight Muay Thai in Las Vegas, NV this Saturday (May 11th).

“I am excited to finally test my skills against top level amateur opponents,” said Bertholdo, a member of Black House Team Nogueira, the famed training camp that is also home to Silva and is headed by MMA legends and twin brothers Antonio “Rodrigo” and Antonio “Rogerio” Nogueira in San Diego, Calif. where he trains under Kru (trainer) Alex Palma.

Still young in his combat career, the 19-year-old talent likes to focus on the striking aspect of combat.

“Striking is my passion,” he said. “My Kru (trainer) has really taught me to use my hands and angles and, because of this, I’ve learned to appreciate the beauty of Muay Thai. MMA is a sport that I eventually will focus on in the future but, for now, I want to sharpen my striking and compete in an all-striking sport.”
