Saul Alvarez believes that he will have an edge over Floyd Mayweather Jnr when they clash on September 14.

The Mexican squares off against the unbeaten 'Money' at welterweight in Las Vegas and Alvarez feels that his natural attributes will give him an advantage over the majestic Mayweather.

"I'm younger and bigger, which are very important keys," Alvarez told reporters.

"Obviously, this is my biggest fight, but I've visualized it and I've prepared my mind for it for a while.

"I appreciate all the fans for all of their incredible support. I always have. I'm very gratified to be here today, to see this turnout and to have so many fans supporting for me. I'll be ready on September 14 and give them all what they want to see."

'Canelo' Alvarez was victorious over Austin Trout in his last fight back in April.
