Pound-for-pound champion Floyd Mayweather Jr. ended all speculation that has been circulating around the boxing world for the past few weeks after he confirmed that he will be fighting WBC and WBC junior middleweight champion Canelo Alvarez on September 14 at MGM Grand in Las Vegas, Nevada.

Mayweather, who's coming off of a unanimous decision victory over Robert Guerrero on May 4, unveiled the identity of his next opponent on his Twitter account.  

"I chose my opponent for September 14th and it's Canelo Alvarez. I'm giving fans what they want. It will be at the MGM Grand," Mayweather tweeted on Wednesday.

Mayweather has been the gold standard in boxing for the last 10 years or so, but fighting a young and hard-hitting champion like Alvarez presents a real test to the five-division champ's invincibility in the sport.

The 36-year old boxer has been spectacular in his last three fights, scoring a knockout win over Victor Ortiz before showcasing a wide repertoire of boxing skills against former champs Miguel Cotto and Guerrero.

On the other hand, the 22-year old Alvarez is also undefeated in 43 professional fights, 31 of which coming in a way of a knockout. Even at his young age, Canelo boasts victories over a number of former champs and even future boxing Hall of Famer such as Carlos Baldomir, Shane Mosley and Austin Trout.

Although his last win over Trout was marred with controversy, Alvarez is no doubt the most worthy opponent to fight Mayweather.

Canelo's skills set and increasingly growing fan base instantly makes him the hottest pick for Mayweather logically and financially, ever since a boxer named Manny Pacquiao suffered a devastating knockout last December.

But the biggest question remains unanswered is the stipulations of the bout. Will Mayweather demand a clause that will prevent Canelo from bloating up to 175 pounds at fight night? Stay tuned.
