Boxing legends Sugar Shane Mosley and Erik “El Terrible” Morales have different opinion about Saul “Canelo” Alvarez.

In his last bout, pound-for-pound boxing superstar  Canelo defeated Sergey Kovalev  via KO to become the new WBO Light Heavyweight champion. With this victory, the Mexican warrior once again made history by becoming a four-division world champion and only the second Mexican fighter ever to capture the 175 pound title.

After Canelo’s historic win, Mosley was convinced that his former fow has already cemented his name as “pound-for-pound’s best.” In an interview with Little Giant Boxing, Mosley emphasized that Canelo as his peak and world champions will find it “very hard to beat him.”

“When I fought hi he was 20 years old so he was like 29 right now so he’s still young. And now I think he has reached his peak. It’s gonna be very hard to beat him. He’s a bad boy,” Mosley said about Canelo.

“I think Canelo is the best, Pound-for-Pound’s best right now,” Mosley added.

Prior to Kovalev fight, Morales, another legendary boxer, thought that Canelo has the ability to be crowned champion in four different weight divisions. However, he has been questioning his fellow Mexican’s manner in picking opponents.

According to Morales, Canelo is a great boxer but he seems to be fighting world champions who are already passed their primes, Boxing Scene reported.

“[Canelo] has fought with big names when they are at the end of their career. Shane Mosley was at the end of his career, Miguel Cotto was at the end of his career, Kovalev is at the end of his career,” Morales said.

Morales even brought up Gennady Golovkin’s name and stated that Canelo was just waiting for his biggest rival to “deteriorate.” And instead of facing Golovkin, Canelo chose an easier opponent in Kovalev.

“With [Gennady] Golovkin, he is already [far along in years] and [Canelo] has been waiting for him to deteriorate. This is something that people see,"  Morales pointed out.

“People and I had hoped that the fight against GGG would have taken place and instead they choose an opponent who, for many is already old, he [Kovalev] is already old and won't present real competition ,” Morales continued.

Moments after Canelo defeated Kovalev, Juan Manuel Marquez also had the same thought as Morales. As per Marquez, Canelo needs to fight champions who are in their prime to be considered an all-time great.

“Not yet. He needs opponents with great names. He needs to prove everything on the ring,” Marquez answered when asked if Canelo belongs to the list of all-time boxing greats.

“Kovalev is a good fighter but Kovalev is going down in his career,” Marquez added.
