Danny Garcia confident ahead of second showdown with Erik Morales in Brooklyn

Danny Garcia and Erik Morales: went the full 12-round distance in their first fight back in March

Danny Garcia believes he is "too smart" to lose to Erik Morales as he prepares to face-off against the Mexican ring legend for a second time this year.

Light-welterweight Garcia puts his WBA and WBC titles on the line this weekend when he headlines the first championship boxing card to be held in Brooklyn, New York for 80 years.

The 24-year-old from Philadelphia, nicknamed 'Swift', defeated Morales on points back in March to claim the WBC belt before going on to stun Amir Khan four months later, knocking out the Brit in Las Vegas.

"I always go for the knockout," Garcia - who has a perfect 24-0 record - said. "The fans love it. That's what I do, I bring the knockout power.

"I definitely expect to win. I've been training so hard. I'm too smart and I can't see myself losing to anyone anytime soon."

Morales, however, took Garcia the distance in their first meeting and is confident he can avenge that first defeat this weekend at the Barclays Center, a new stadium that also homes the NBA team the Brooklyn Nets.

"We're totally prepared," the four-division champion said. "We're very hurt over what happened in March and we have done everything possible to be ready for this Saturday."

The bout is still scheduled to go ahead despite Morales reportedly failing a doping test. His 'B' sample will not be tested until after the fight, though the New York State Athletic Commission will have the final say.
