Mexican looking to maintain unbeaten record against Rubio

Julio Cesar Chavez Jr claims he will prove himself the best middleweight fighter on the planet when he puts his WBC title on the line against compatriot Marco Rubio on Saturday. The 26-year-old, son of legendary six-time world champion Julio Cesar Chavez Sr, is aiming to maintain his unbeaten 44-0-1 record when he takes on Rubio in San Antonio at the weekend. If he emerges victorious, Chavez Jr will achieve something his father never did and that is to win at the San Antonio Alamodome with Chavez Sr having been held to a draw at the venue by Pernell Whitaker in 1993. But Chavez Jr has his sights set firmly on a convincing triumph, stating: "This fight will leave no doubt that I am the top middleweight in the world." However, big-punching Rubio - who has 46 knock-outs in his tally of 53 career wins - insists he will push his countryman all the way. "I'm gonna give all my heart in the ring," said the rugged 31-year-old from Coahuila.
