Danny Garcia has complete confidence in his ability to see off the challenge of former champion Zab Judah on April 27.
Garcia is the WBC and WBA light-welterweight champion with an impressive 25-0 record, and at 25 is 10 years younger than his opponent.
But the Philadelphian has little respect for Judah, who held the IBF strap until he suffered a crushing knockout loss to Kostya Tzsyu as long as 12 years ago.
"He is just another guy in my way," he said. "They all say the same thing. They think they're going to beat me...until we get into that ring.
"I've fought tons of southpaws in the amateurs and in the pros. It's easier for me because I can land my hard left hand and hard left hook.
"Experience doesn't mean anything when you get hit. It is about how you can take a punch. When you get hit and let your hands go, experience doesn't matter.
"I'm not really concerned about anything. I know I'm going to be at 110 percent and in perfect shape.
"You are going to see the best Danny Garcia on April 27. I am predicting a fourth round knockout."
