Floyd Mayweather says he feels 'unbeatable' ahead of Guerrero bout
Ahead of bout against Guerrero, fighter says neither jail time nor furlough has weakened him

Unbeaten American star Floyd Mayweather Jnr says neither jail time nor ring rust from a one-year lay-off will diminish him next week when he returns against compatriot Robert Guerrero.
"Of course I feel unbeatable. I'm in the sport where I'm the best," Mayweather said. "I'm not going into the fight thinking I'm beatable."
Mayweather, 43-0 with 26 knockouts, will defend his World Boxing Council welterweight title against southpaw Guerrero, 31-1 with 18 knockouts, on May 4 in Las Vegas, a year after beating Miguel Cotto by unanimous decision.
It will be Mayweather's first fight since serving two months in jail for domestic battery, a fact that gives challenger Guerrero a confidence boost.
"Most definitely Floyd Mayweather is taking me seriously," Guerrero said. "It has been his longest training camp in a long time. Being a whole year's lay-off, he's going to feel the punches. We're going after him the whole fight. It's going to take a little time to shake that ring rust off."
