I am Roberto Matsumoto. I am 22 years old and I have been training jiu-jitsu for 6 years. I have already fought in the major Brazilians events, with or without gi and I am considered one of the best in my weight class.
I can say that Marcello C. Monteiro is a specialist in fighting strategies, attacking guard and half guard positions. We have already trained many times and I would like to point out his technical knowledge.
Roberto Matsumoto - Three times São Paulo State Champion with and without Gi.
