Anderson Silva and Nick Diaz engaged in a conference call with the media yesterday to discuss their upcoming bout.

Mostly, the questions stayed “on topic” — with both describing their preparation for the bout.

“Nick Diaz is a great fighter,” Silva said, in improving English. “Good boxing and good jiu-jitsu. We’re going to have the best fight for the UFC.”

Regarding his preparation for the bout, at a new weight division (middleweight), Diaz remarked: “I’m going to feel a little stronger and more energetic; things are going well.”

Will he stay at 185 lbs?  “I’ve got to survive this fight before I decide to stay there,” he answered. “We’ll see how this looks.”

But things got interesting when Silva was asked about possible future match-ups with his countrymen Ronaldo “Jacare” Souza and Lyoto Machida.

While both have said they would be willing to set aside their friendships to fight, Silva has maintained he would not — and expressed frustration about it.

“I don’t like to fight Brazilian guys,” Silva said plainly.

“Jacare is my friend, Lyoto is my friend, but the guys don’t talk the same to me,” Silva explained. “When I talk to media, I say I don’t want to fight Lyoto because he’s my friend. I don’t want to fight Jacare because he’s my friend. But when they talk to the media, they say I’ll fight…’I’ll fight because I’m a fighter.’ My opinion is, I don’t like the position of Lyoto and Jacare. I don’t want to fight these guys. I trained with Lyoto for a long time, and I train sometimes with Jacare.”

Does it anger you, the old champion was asked?

“Yeah, absolutely,” he said. “I train and help these guys. I put my energy into helping these guys. When guys talk like this I’m very very disappointed. I think I need to talk to these guys. ”
