Cotto (37-3, 30 KO) and adviser Bryan Perez, according to Boxing News 24, have revealed Bradley (29-0, 12 KO) and Alvarez (40-0-1, 29 KO) as two of the top choices for Cotto's next opponent.
WBO world welterweight champ Bradley has stated that he'll "entertain" a fight with Cotto, stating that he used to fight at 152 pounds in the Olympics.
The only thing going against Bradley is that he's aligned himself with Top Rank Promotions.
Cotto is currently in negotiations to co-promote his December 1 return to Madison Square Garden with Golden Boy Promotions.
WBC world junior middleweight champ Alvarez is promoted by Golden Boy Promotions and remains the more proven commercial draw.
Both choices are undefeated, strong athletes in their primes. A fighter such as Cotto must leverage the pros and the cons of either man. Here's a look at what each man brings to the table.
