Golden Boy Promotions President Oscar De La Hoya believes Floyd Mayweather Jr. (44-0, 26KOs) is feeling a sense of insecurity with the upcoming fight against WBC/WBA junior middleweight champion Saul "Canelo" Alvarez (42-0-1, 30KOs).

The fight takes place at a catch-weight of 152-pounds. Mayweather had previously fought at the full junior middleweight limit of 154 on two occasions, against De La Hoya in 2007 and last year against Miguel Cotto. Both fights were tough outings for the pound-for-pound king, with Mayweather winning both by way of twelve round decision.

De La Hoya says the fact that a catch-weight is in place for this match, signals that Mayweather is taking Canelo far more seriously than other past opponents.

"Obviously the fact that he's asking for a catch-weight, already there are insecurities. Right from the start [there are insecurities]. I read somewhere, where Canelo mentioned, or someone mentioned that [Canelo] won round one - well he won round one. It's funny because the weight of 152 - it's not going to help Mayweather. On the contrary, its going to benefit Canelo," De La Hoya told krikya360.com.

De La Hoya explained how Canelo will benefit from the catch-weight clause.

"For this fight, Canelo is going to have a nutritionist, which he's never hard before. He's going to have his team in his corner, but the key is getting the nutritionist - that's going to make him stronger, make him faster. The key is not being strong, the key against Mayweather is being fast and to be in great shape - and that's what Canelo is going to be on September 14th," De La Hoya said.

When De La Hoya fought Mayweather, he came very close to handing Floyd his first pro loss. One judge had De La Hoya winning 115-113, while the other two sided with Mayweather with scores of 115-113 and 116-112. De La Hoya says his key weapon was the jab - something that most fighters forget to use these days.

"I've always preached for years that in order to beat that kind of style - you need a jab. A jab is a lost art form. Fighters forgot about the jab. [Fighters] are just looking to knock everybody's head off," De La Hoya said.
