The feathery fisted Trout (26-2, 14 KOs) lost on the cards to both Lara and Alvarez in 2013.
"Lara is the better boxer," said Trout, 28, who outperformed Puerto Rican icon Miguel Cotto in December 2012. "Canelo may be strong but I don't think he'll be able to land on Lara. I've got Lara by unanimous decision."
Lara, a lefty who defected from Cuba in 2008, last vacated the squared circle on December 7 after universally outscoring Austin Trout to capture the WBA light middleweight title.
Comparatively, rebounding from a loss to Floyd Mayweather, Alvarez most recently earned an emphatic 10th round TKO victory over Alfredo Angulo in March.
Using brilliant movement and a diversified attack, Canelo landed left hooks, straight rights and uppercuts at will.
Looking sharp, fast and powerful, Alvarez quickly established that the 31-year-old Angulo (22-4, 18 KOs) wasn’t a worthy adversary.
Considering the fierce redhead has always thrived against southpaws, Alvarez should easily penetrate Lara’s guard and cause extensive damage.
In contrast to the educated thoughts of Trout, Lara is not “the better boxer” than Canelo.
Ultimately, known as “The American Dream,” Erislandy Lara will soon be rendered unconscious by Saul Alvarez within eight rounds in Sin City.
