Robert Guerrero has refused to get drawn into a slanging match ahead of Saturday’s fight with Danny Garcia.

In the opposing corner Garcia has vocally predicted a 5th round KO victory but Guerrero is relishing coming in as the underdog.

"Danny Garcia is very confident coming into this fight. He said he's going to knock me out in five rounds. His dad said they're bringing the storm to California. They both said it's going to be the Danny Garcia show, so we'll see.”

Fresh from victory over Aaron Martinez last time out, the 32 year old southpaw is fully concentrated on the job at hand.

“All I know is I'm coming to fight. I'm going to do all my talking in the ring with my fists.”

Saturday night’s fight for the vacant WBC World Welterweight Title will continue the fascinating Mexican and Puerto Rican boxing derby.

"The Garcia’s can try to downplay the Mexican vs. Puerto Rican rivalry all they want, but the fact is, this rivalry has been the cornerstone of great boxing matches since before I was born. We are both born in America, but our roots go back to Mexico and Puerto Rico, so expect the rivalry to continue. I can't wait to silence all the critics who are writing me off," revealed Guerrero.
