Citing a lack of “speed” and “stamina,” Top Rank promoter Bob Arum predicts Floyd Mayweather Jr will overwhelm Saul “Canelo” Alvarez onSeptember 14 in Las Vegas, Nevada.

"Canelo doesn't have the speed or the stamina to cope with Mayweather Jr," Arum told "The problem is Canelo, and a lot of young fighters, don't have the stamina. They run out of gas. That's what happened to him in the Austin Trout fight. I think Mayweather Jr will decision or stop him."

The 22-year-old Alvarez (42-0-1, 30 KOs) most recently vacated the squared circle on April 20 after outscoring Trout (26-1, 14 KOs) to unify the WBC and WBA super world light middleweight titles.

A corruptible weasel who has acknowledged using bribery, the 82-year-old Arum must have missed “Canelo’s” scrap against Trout.

Although handcuffed with feathery fists, Trout is a defensive wizard with a prolific jab and advanced ring smarts.

Hence, it’s not surprising that Trout gave Alvarez such a tough battle.

Boxing professionally since the ludicrous age of 15, the Mexican superstar has plenty of “stamina” and certainly wasn’t struggling with endurance issues versus Trout.

As the reigning pound-for-pound king, the 36-year-old Mayweather (44-0, 26 KOs) is one of the premier performers in the annals of prizefighting.

In a bruising clash, Mayweather should ultimately outdo “Canelo” and emerge triumphant.

However, in stark contrast to Bob Arum’s thoughts, Saul Alvarez will not fall to Floyd Mayweather after “(running) out of gas.”
