An interview by Tatame with Andre Galvao revealed that Galvao, a Brazilian Jiu-Jitsu champion, is working with "The Axe Murderer" Wanderlei Silva (31-7-1) on his ground technique. Wanderlei Silva is already a black belt in Brazilian Jiu-Jitsu, but it looks like he wants to start rounding out his game a little more. His vicious knockouts are what he's known for, but maybe we'll see him submit Chuck Liddell at UFC 79 (20-5-0).
