Diaz believes McGregor sleeps haunted by loss

For a fighter who usually lets his fists do the talking, Nate Diaz certainly has a grasp on verbally jousting with Conor McGregor.

Of course, it helps that Diaz can hold a victory over McGregor's head since submitting "The Notorious" at UFC 196 in March. The way he sees it, all of McGregor's efforts to discredit the win and motivate himself are a waste of time.

"He remembers what happened in the last fight," said Diaz at a UFC 202 press conference Wednesday. "I think it's a little silly, man, he's got pictures of me up in his garage and he's punching me in the face. What the f---? Who does that? Trying to make yourself believe something, just trying to hype himself up, but when he goes to sleep at night, he remembers what happened the last time."

One sticking point McGregor and his camp keep bringing up is the fact that their first meeting took place at welterweight, two divisions higher than usual for McGregor. Diaz himself has only competed at 170 pounds a handful of times, so he sees any talk about him having a size advantage as a crutch for McGregor to stand on.

"It's not that big of a weight advantage when he was talking about coming up to welterweight, fighting Robbie Lawler and taking the belts and all this stuff," said Diaz. "All of a sudden I've got 30 pounds on him and they're making excuses for whatever. He fought at 145 pounds and 155 pounds in his career and I've fought at 155 pounds my whole career. I had a couple of fights at 170.

"I don't know how I all of a sudden became this monstrous heavyweight against Conor McGregor just because I won the fight."

McGregor and Diaz meet in a welterweight rematch at UFC 202 on Saturday in Las Vegas.
